Why is optical fiber communication popular?
Because it's much faster than copper wire - and almost impossible to 'tap' without being detected !
The advantage of wireless communication over optical fiber are as follows : the cost of wireless communication is much less over optical fiber communication : unlimited no of users can be installed which is not so easier in Optical fibers : maintanence of wireless communcation system is cheaper than Optical fiber communication.
How do you design point to point optical fiber communication link with 200 channels over a short distance?
You will need a special card for each PC that would convert the communication signals (electrical signals) into optical code. Then you would connect the optical ports of both machines together via fiber optic cable. Ideally one card (one per machine) would be able to transmit and receive optical code over two strands of fiber. One strand for transmit the other for receive.
There are actually about 10 types of Fiber Optic Cables. OFC: Optical fiber, conductive OFN: Optical fiber, nonconductive OFCG: Optical fiber, conductive, general use OFNG: Optical fiber, nonconductive, general use OFCP: Optical fiber, conductive, plenum OFNP: Optical fiber, nonconductive, plenum OFCR: Optical fiber, conductive, riser OFNR: Optical fiber, nonconductive, riser OPGW: Optical fiber composite overhead ground wire ADSS: All-Dielectric Self-Supporting
# Optical fibres can carry more information as opposed to conventional cables. # Optical fibres are not affected by radio frequency interferrence # Information carried in an optical fibre can only be tapped physically (to steal information, the thief has to work on the optical fibre so that the light will travel to the thief)
an optical fiber is used for things like telecommunication and networking Optical fibres are signal transmission lines similar to usual lines except that they conduct light instead of electricity and are made out of glass instead of metal. They are very superior in modern communication schemes Apart from pretty lighting effects - they can be used to send Huge ammounts of data, quickly Communication networks and lighting etc.
