An optical fiber (or optical fibre) is a flexible, transparent fiber made of extruded glass (silica) or plastic, slightly thicker than a human hair. It can function as a waveguide, or “light pipe”, to transmit light between the two ends of the fiber. The field of applied science and engineering concerned with the design and application of optical fibers is known as fiber optics.
Optical fibers are widely used in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data rates) than wire cables. Fibers are used instead of metal wires because signals travel along them with less loss and are also immune to electromagnetic interference. Fibers are also used for illumination, and are wrapped in bundles so that they may be used to carry images, thus allowing viewing in confined spaces. Specially designed fibers are used for a variety of other applications, including sensors and fiber lasers.
Optical fibers typically include a transparent core surrounded by a transparent cladding material with a lower index of refraction. Light is kept in the core by total internal reflection. This causes the fiber to act as a waveguide. Fibers that support many propagation paths or transverse modes are called multi-mode fibers (MMF), while those that only support a single mode are called single-mode fibers (SMF). Multi-mode fibers generally have a wider core diameter, and are used for short-distance communication links and for applications where high power must be transmitted. Single-mode fibers are used for most communication links longer than 1,000 meters (3,300 ft).
Joining lengths of optical fiber is more complex than joining electrical wire or cable. The ends of the fibers must be carefully cleaved, and then carefully spliced together with the cores perfectly aligned. A mechanical splice holds the ends of the fibers together mechanically, while fusion splicing uses heat to fuse the ends of the fibers together. Special optical fiber connectors for temporary or semi-permanent connections are also available.

What is Fiber Optics?
Fiber optic cable in essence, is a hair-like glass conduit that carries virtually any type of signal from one point to another at light speed. In case you are wondering why light traveling through fiber optic cable does not actually travel at true light speed, it is because the glass that makes up fiber optic cable is denser than the vacuum of outer space where light can travel without disruption. Needless to say, a fiber optic light signal is still much faster and far superior to a copper based signal, which is why it has become so popular in the cable television, telecommunications and computer networking. Unlike copper based signals, fiber signals are not affected by external power sources or surges and there is no need for shielding or grounding.
How are Fiber Optics used today?
Today, practically every communication network contains fiber optics. In most cases, fiber optics are used because of their convenience. Fiber optic cable allows network builders to divide their network into smaller service areas that prevent large numbers of customers from being affected in an outage. The result is better service and customer relations. Fiber optic cable also gives them a fast return path, which they use for Internet and telephone connections, thereby increasing their revenue potential.
The use of fiber optics is not just limited to communication networks. Cable and telephone providers often use fiber for its distance capabilities. Distance is also an advantage to industrial plants that use vast amounts of fiber primarily for its noise immunity. Utilities also prefer fiber for noise immunity, security and high bandwidth properties. The military uses fiber because it's nearly tap-proof and impossible to jam. Fiber is even used by the aviation and aerospace industries because of its smaller size and weight.
What are the advantages of Fiber Optics over Copper wire?
Fiber's extra distance capability and seemingly unlimited data rate makes it possible to do things not possible with copper wire. For example, you can install all the electronics for a network in one communications closet for a building and run straight to the desk with fiber. With copper, you can only transmit about 90 meters (less than 300 feet), thus requiring more telecom closets in each building. With fiber, you only need passive patch panels locally to allow for moves. Upgrades can be rather difficult with copper wire, but not with fiber because the real capacity of fiber is only partially utilized at today's network speed. Many use fiber to connect all their central offices and long distance switches because it has thousands of times the bandwidth of copper wire and can carry signals hundreds of times further before needing a repeater. The cable and telephone providers use fiber because it gives them greater reliability with the opportunity to offer new services, like digital phone service and Internet connections. They also use fiber for economic reasons, but their cost justification requires adopting new network architectures to take advantage of the fiber's strengths.

This picture shows a bunch of fiber enclosed in a single black color protective jacket.
So how is light guided and travels inside the fiber? This video shows a beam of light that travels inside a water stream by total internal reflection. Optical fibers work the same way. So let's take a look.
A glass fiber has a cylindrical structure and is composed of three layers. At the center is the core, core has higher refractive index. Outside of core is the cladding layer. Cladding layer has lower refractive index than the core.
The third layer is a plastic buffer coating. This buffer coating doesn't affect the fiber's optical performance, it is there for mechanical protection only.
The right picture shows how light is coupled into the fiber's core and bounced back and forth in the core and travels along the fiber.
The core and cladding layers are all based on fused silica which is a type of glass. But this fused silica is extremely clear, with almost no impurities. This transparency is extremely important, so that the light can travel for a very long distance, such as hundreds of kilometers with minimum loss. This makes trans-Pacific and trans-continent fiber optic communications possible.
Here comes the question. Why doesn't the light leak out of the fiber? That is why we have to explain the phenomenon of total internal reflection.
The left picture shows Snell's the law which guides how light travels at the interface of the core and cladding.
The core has a higher refractive index n = 1.5. The cladding has a lower refractive index n = 1.4. When light incidents at the interface between the core and cladding at different angles, some power is reflected back, and some power enters into the cladding which is refracted. But when we increase the incident angle to greater than a critical angle theta c, no more light enters into the cladding, all light is reflected back into the core. This phenomenon is called Total Internal Reflection. Here total means 100% of the power is reflected back into the core.
The manufacturing of glass fibers go through two steps. In the first step a preform is made. This preform has exactly the same proportion of core and cladding as final fiber product, but in a much bigger size. It looks like a thick glass rod, as shown in the bottom picture.
Then the preform is hanged at the top of a fiber drawing tower. The tower is a couple of stories tall as shown in the right picture.
The preform is heated by a furnace which softens the glass. The softened glass drips and pulled downward by gravity. A diameter monitor carefully monitors the fiber's diameter, which usually is 125um. Then the coater deposits a layer of plastic buffer coating for mechanical protection, which usually is 250um in diameter.
And finally, the fiber is winded onto a spool for storage and transportation.
A basic fiber optic communication system must have at least three components. The light source, which usually is a laser. The laser is turned on and off quickly by a driving circuit. In this modulation process, the original electronic signal is translated into light signal.
The second part is the fiber. The fiber's purpose is to transmit the light through a very long distance, such as from New York to Paris.
And the third part is a photodetector. The photodetector detects the light and generates electronic current, in this process it translates the light signal back into electronic signal.
This table list the most common high speed Ethernet standards. For 100 Mbps, copper supports up to 100 meters, while fiber supports up to 40 kilometers. For Gigbit Ethernet, copper supports still 100 meters, fiber supports 70 kilometers. For 10 Gigbit Ethernet, copper is 100 meters, and fiber is 80 kilometers. Now you see the difference.
The bottom picture shows the size comparison between a copper cable and an optical fiber, both carries the same bandwidth.
There is truly no match for fiber's bandwidth capabilities. In order to fully utilize the fiber's bandwidth, people are using WDM technologies to increases the bandwidth in tens of folds.
WDM stands for Wavelength Division Multiplexer. What this means is that many different colors, or wavelengths, of light is put into a single fiber. This picture shows a simple 4 channel WDM, but there are 32 channels, 64 channels, or even more are available on the market now.
Now imagine how many information can a single fiber carry. If each wavelength carries 40 Gbps signal, then a 10 channel WDM system can carry 400 Gbps. Not to mention a 100 channel WDM system.

Before fiber optic networks can be constructed, they must be properly designed, and once constructed they must be managed. Efficiency in these processes translate into lower cost layout and construction, more productive system migration and field operations, lower optical loss budget, and greater business profitability by bringing fiber to the desk.

Google is reinforcing its underwater fibre-optic cables to protect against future shark attacks
Google is reinforcing its private underwater fibre-optic cables with an extra layer of protective material in order to protect its 100,000 miles of cables from sharks.
Sharks and other fish are attracted to the cables, thought by some to be due to the electromagnetic signals emitted by the lines, but they are easily damaged. The cables already have existing protective materials designed to shelter them from the various dangers of the environment, but will now be coated with a 'Kevlar-like' material to provide even more protection.
Fibre-optic cables are made of strands of glass, and are thus much less durable than copper cables. Google wants to prevent its own cables from sustaining further damage after seeing underwater surveillance footage of sharks biting the cables.
IT Pro has contacted Google for more information on the plans and will update the story as soon as we know more.

http://mocomi.com/ presents: What is Fiber Optics?
Fiber optics or Optical Fibers are very thin and flexible strands of glass which are used today to transmit data over long distances with minimum loss.
Watch this interesting video explaining what is fiber optics, how it works, uses and conclusion with the help of this animated learning module for kids.
An optical fiber is a semi-flexible, transparent, and extremely thin strand of pure glass that has the diameter of a human hair. Thousands of these strands are arranged in bundles to make a thicker cable. Since glass is optically transparent we are able to send information-laden rays of light over long distances.
A fiber optic cable is made up of five parts:
Strands of glass that are bundled together to make one single channel of light called makes up the core. The diameter of the core dictates how much information can be sent and received at once.
A protective sheath or coating around any structure or material is known as the cladding. In fiber optic cables the silica cladding increases the total internal reflection of the core. Therefore a light pulse can pass through the entire length of the fiber with little data loss.
A layer of plastic surrounds the core and cladding to reinforce the fiber core. The coating provides extra protection and prevents the cable from bending too much.
The strengthening fibers around the coating give added support to the coating especially when it comes to stretching tension.
Finally all this is covered in the cable jacket like any other cable or wire.
The only part of a fiber optic cable that carries data is the tiny core in the center but it has layer upon layer of protection because glass is extremely brittle and in order for it to function at its best, there can be no breaks in the fiber at all. Add to that the high cost of producing them and you will know why every precaution must be taken to prevent damage.

Fiber Optics, How it works??
An optical fiber (or optical fibre) is a flexible, transparent fiber made of extruded glass (silica) or plastic, slightly thicker than a human hair. It can function as a waveguide, or “light pipe”, to transmit light between the two ends of the fiber. The field of applied science and engineering concerned with the design and application of optical fibers is known as fiber optics. Optical fibers are widely used in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data rates) than wire cables. Fibers are used instead of metal wires because signals travel along them with less loss and are also immune to electromagnetic interference. Fibers are also used for illumination, and are wrapped in bundles so that they may be used to carry imag... -

Shark Bites Fiber Optic Cables Undersea 15.8.2014
Google is reinforcing its underwater fibre-optic cables to protect against future shark attacks Google is reinforcing its private underwater fibre-optic cables with an extra layer of protective material in order to protect its 100,000 miles of cables from sharks. Sharks and other fish are attracted to the cables, thought by some to be due to the electromagnetic signals emitted by the lines, but they are easily damaged. The cables already have existing protective materials designed to shelter them from the various dangers of the environment, but will now be coated with a 'Kevlar-like' material to provide even more protection. Fibre-optic cables are made of strands of glass, and are thus much less durable than copper cables. Google wants to prevent its own cables from sustaining further d... -

Fibers are used instead of metal wires because signals travel along them with less loss and are also immune to electromagnetic interference. Fibers are also used for illumination, and are wrapped in bundles so that they may be used to carry images, thus allowing viewing in confined spaces. Specially designed fibers are used for a variety of other applications, including sensors and fiber lasers.
Optical fibers typically include a transparent core surrounded by a transparent cladding material with a lower index of refraction. Light is kept in the core by total internal reflection. This causes the fiber to act as a waveguide. Fibers that support many propagation paths or transverse modes are called multi-mode fibers (MMF), while those that only support a single mode are called single-mode fibers (SMF). Multi-mode fibers generally have a wider core diameter, and are used for short-distance communication links and for applications where high power must be transmitted. Single-mode fibers are used for most communication links longer than 1,000 meters (3,300 ft).
Joining lengths of optical fiber is more complex than joining electrical wire or cable. The ends of the fibers must be carefully cleaved, and then carefully spliced together with the cores perfectly aligned. A mechanical splice holds the ends of the fibers together mechanically, while fusion splicing uses heat to fuse the ends of the fibers together. Special optical fiber connectors for temporary or semi-permanent connections are also available.

What is Fiber Optics?
Fiber optic cable in essence, is a hair-like glass conduit that carries virtually any type of signal from one point to another at light speed. In case you are wondering why light traveling through fiber optic cable does not actually travel at true light speed, it is because the glass that makes up fiber optic cable is denser than the vacuum of outer space where light can travel without disruption. Needless to say, a fiber optic light signal is still much faster and far superior to a copper based signal, which is why it has become so popular in the cable television, telecommunications and computer networking. Unlike copper based signals, fiber signals are not affected by external power sources or surges and there is no need for shielding or grounding.
How are Fiber Optics used today?
Today, practically every communication network contains fiber optics. In most cases, fiber optics are used because of their convenience. Fiber optic cable allows network builders to divide their network into smaller service areas that prevent large numbers of customers from being affected in an outage. The result is better service and customer relations. Fiber optic cable also gives them a fast return path, which they use for Internet and telephone connections, thereby increasing their revenue potential.
The use of fiber optics is not just limited to communication networks. Cable and telephone providers often use fiber for its distance capabilities. Distance is also an advantage to industrial plants that use vast amounts of fiber primarily for its noise immunity. Utilities also prefer fiber for noise immunity, security and high bandwidth properties. The military uses fiber because it's nearly tap-proof and impossible to jam. Fiber is even used by the aviation and aerospace industries because of its smaller size and weight.
What are the advantages of Fiber Optics over Copper wire?
Fiber's extra distance capability and seemingly unlimited data rate makes it possible to do things not possible with copper wire. For example, you can install all the electronics for a network in one communications closet for a building and run straight to the desk with fiber. With copper, you can only transmit about 90 meters (less than 300 feet), thus requiring more telecom closets in each building. With fiber, you only need passive patch panels locally to allow for moves. Upgrades can be rather difficult with copper wire, but not with fiber because the real capacity of fiber is only partially utilized at today's network speed. Many use fiber to connect all their central offices and long distance switches because it has thousands of times the bandwidth of copper wire and can carry signals hundreds of times further before needing a repeater. The cable and telephone providers use fiber because it gives them greater reliability with the opportunity to offer new services, like digital phone service and Internet connections. They also use fiber for economic reasons, but their cost justification requires adopting new network architectures to take advantage of the fiber's strengths.

This picture shows a bunch of fiber enclosed in a single black color protective jacket.
So how is light guided and travels inside the fiber? This video shows a beam of light that travels inside a water stream by total internal reflection. Optical fibers work the same way. So let's take a look.
A glass fiber has a cylindrical structure and is composed of three layers. At the center is the core, core has higher refractive index. Outside of core is the cladding layer. Cladding layer has lower refractive index than the core.
The third layer is a plastic buffer coating. This buffer coating doesn't affect the fiber's optical performance, it is there for mechanical protection only.
The right picture shows how light is coupled into the fiber's core and bounced back and forth in the core and travels along the fiber.
The core and cladding layers are all based on fused silica which is a type of glass. But this fused silica is extremely clear, with almost no impurities. This transparency is extremely important, so that the light can travel for a very long distance, such as hundreds of kilometers with minimum loss. This makes trans-Pacific and trans-continent fiber optic communications possible.
Here comes the question. Why doesn't the light leak out of the fiber? That is why we have to explain the phenomenon of total internal reflection.
The left picture shows Snell's the law which guides how light travels at the interface of the core and cladding.
The core has a higher refractive index n = 1.5. The cladding has a lower refractive index n = 1.4. When light incidents at the interface between the core and cladding at different angles, some power is reflected back, and some power enters into the cladding which is refracted. But when we increase the incident angle to greater than a critical angle theta c, no more light enters into the cladding, all light is reflected back into the core. This phenomenon is called Total Internal Reflection. Here total means 100% of the power is reflected back into the core.
The manufacturing of glass fibers go through two steps. In the first step a preform is made. This preform has exactly the same proportion of core and cladding as final fiber product, but in a much bigger size. It looks like a thick glass rod, as shown in the bottom picture.
Then the preform is hanged at the top of a fiber drawing tower. The tower is a couple of stories tall as shown in the right picture.
The preform is heated by a furnace which softens the glass. The softened glass drips and pulled downward by gravity. A diameter monitor carefully monitors the fiber's diameter, which usually is 125um. Then the coater deposits a layer of plastic buffer coating for mechanical protection, which usually is 250um in diameter.
And finally, the fiber is winded onto a spool for storage and transportation.
A basic fiber optic communication system must have at least three components. The light source, which usually is a laser. The laser is turned on and off quickly by a driving circuit. In this modulation process, the original electronic signal is translated into light signal.
The second part is the fiber. The fiber's purpose is to transmit the light through a very long distance, such as from New York to Paris.
And the third part is a photodetector. The photodetector detects the light and generates electronic current, in this process it translates the light signal back into electronic signal.
This table list the most common high speed Ethernet standards. For 100 Mbps, copper supports up to 100 meters, while fiber supports up to 40 kilometers. For Gigbit Ethernet, copper supports still 100 meters, fiber supports 70 kilometers. For 10 Gigbit Ethernet, copper is 100 meters, and fiber is 80 kilometers. Now you see the difference.
The bottom picture shows the size comparison between a copper cable and an optical fiber, both carries the same bandwidth.
There is truly no match for fiber's bandwidth capabilities. In order to fully utilize the fiber's bandwidth, people are using WDM technologies to increases the bandwidth in tens of folds.
WDM stands for Wavelength Division Multiplexer. What this means is that many different colors, or wavelengths, of light is put into a single fiber. This picture shows a simple 4 channel WDM, but there are 32 channels, 64 channels, or even more are available on the market now.
Now imagine how many information can a single fiber carry. If each wavelength carries 40 Gbps signal, then a 10 channel WDM system can carry 400 Gbps. Not to mention a 100 channel WDM system.

This picture shows a bunch of fiber enclosed in a single black color protective jacket.
So how is light guided and travels inside the fiber? This video shows a beam of light that travels inside a water stream by total internal reflection. Optical fibers work the same way. So let's take a look.
A glass fiber has a cylindrical structure and is composed of three layers. At the center is the core, core has higher refractive index. Outside of core is the cladding layer. Cladding layer has lower refractive index than the core.
The third layer is a plastic buffer coating. This buffer coating doesn't affect the fiber's optical performance, it is there for mechanical protection only.
The right picture shows how light is coupled into the fiber's core and bounced back and forth in the core and travels along the fiber.
The core and cladding layers are all based on fused silica which is a type of glass. But this fused silica is extremely clear, with almost no impurities. This transparency is extremely important, so that the light can travel for a very long distance, such as hundreds of kilometers with minimum loss. This makes trans-Pacific and trans-continent fiber optic communications possible.
Here comes the question. Why doesn't the light leak out of the fiber? That is why we have to explain the phenomenon of total internal reflection.
The left picture shows Snell's the law which guides how light travels at the interface of the core and cladding.
The core has a higher refractive index n = 1.5. The cladding has a lower refractive index n = 1.4. When light incidents at the interface between the core and cladding at different angles, some power is reflected back, and some power enters into the cladding which is refracted. But when we increase the incident angle to greater than a critical angle theta c, no more light enters into the cladding, all light is reflected back into the core. This phenomenon is called Total Internal Reflection. Here total means 100% of the power is reflected back into the core.
The manufacturing of glass fibers go through two steps. In the first step a preform is made. This preform has exactly the same proportion of core and cladding as final fiber product, but in a much bigger size. It looks like a thick glass rod, as shown in the bottom picture.
Then the preform is hanged at the top of a fiber drawing tower. The tower is a couple of stories tall as shown in the right picture.

Google is reinforcing its underwater fibre-optic cables to protect against future shark attacks
Google is reinforcing its private underwater fibre-optic cables with an extra layer of protective material in order to protect its 100,000 miles of cables from sharks.
Sharks and other fish are attracted to the cables, thought by some to be due to the electromagnetic signals emitted by the lines, but they are easily damaged. The cables already have existing protective materials designed to shelter them from the various dangers of the environment, but will now be coated with a 'Kevlar-like' material to provide even more protection.
Fibre-optic cables are made of strands of glass, and are thus much less durable than copper cables. Google wants to prevent its own cables from sustaining further damage after seeing underwater surveillance footage of sharks biting the cables.
IT Pro has contacted Google for more information on the plans and will update the story as soon as we know more.

http://mocomi.com/ presents: What is Fiber Optics?
Fiber optics or Optical Fibers are very thin and flexible strands of glass which are used today to transmit data over long distances with minimum loss.
Watch this interesting video explaining what is fiber optics, how it works, uses and conclusion with the help of this animated learning module for kids.
An optical fiber is a semi-flexible, transparent, and extremely thin strand of pure glass that has the diameter of a human hair. Thousands of these strands are arranged in bundles to make a thicker cable. Since glass is optically transparent we are able to send information-laden rays of light over long distances.
A fiber optic cable is made up of five parts:
Strands of glass that are bundled together to make one single channel of light called makes up the core. The diameter of the core dictates how much information can be sent and received at once.
A protective sheath or coating around any structure or material is known as the cladding. In fiber optic cables the silica cladding increases the total internal reflection of the core. Therefore a light pulse can pass through the entire length of the fiber with little data loss.
A layer of plastic surrounds the core and cladding to reinforce the fiber core. The coating provides extra protection and prevents the cable from bending too much.
The strengthening fibers around the coating give added support to the coating especially when it comes to stretching tension.
Finally all this is covered in the cable jacket like any other cable or wire.
The only part of a fiber optic cable that carries data is the tiny core in the center but it has layer upon layer of protection because glass is extremely brittle and in order for it to function at its best, there can be no breaks in the fiber at all. Add to that the high cost of producing them and you will know why every precaution must be taken to prevent damage.
