OFC Optical Fiber Cable

              Optical Fiber Cable  

  OPTICAL FIBER CABLE

An optical fiber cable is a type of cable that has a number of optical fibers bundled together, which are normally covered in their individual protective plastic covers.
Optical cables are used to transfer digital data signals in the form of light up to distances of hundreds of miles with higher throughput rates.

It have very fast data transmission rate, compare to those electrical communication.

 It carries a huge data and works efficiently .  

All optical fibers use a core of hair-like transparent silicon covered with less refractive indexed cladding to avoid light leakage to the surroundings. Due to the extreme sensitivity of the optical fiber, it is normally covered with a high-strength.

Optical cable is the primary source of long-distance, high-bandwidth communications between telephone companies, multisite organizations and various other long-range communications applications.

 OFC MECHANISM

The composition of optical cable starts with the outer jacket, which is made of a strong and often flexible material. This is followed by plastic cover used to bundle individual optical fiber cables. An optical fiber typically consists of 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.

Single-wavelength or multiple-wavelength light is passed through the core and keeps traveling inside the core due to the lower refractive index cladding surrounding it, which bounces the light back when it tries to escape.

HOW THE OFC PERFORM COMMUNICATION

Transmitter - Produces and encodes the light signals.

Optical fiber - Conducts the light signals over a distance.

Optical regenerator - May be necessary to boost the light signal (for long distances).

 Optical receiver - Receives and decodes the light signals.


OFC is widely used in the today telecommunication area. All Operators are working constantly to spread their OFC for fast data network.
It is very costly.  From source it might be 0f 70.00 Indian Rs. per metre for 12 core cable.
