An optical fibre communication system works on a wavelength of `1.3 mu_(m)`. The number of subscribers it can feed if a channel required `20kHz` are

In optical fibre communication system, light source can be

Consider an optical communication system operating at a wavelength of 800 mm and only 1 % of the optical source frequency is the available channel bandwidth for communication. How many channels (in multiple of 10 )-can be accommodated for transmitting audio signals requiring a bandwidth of 8kHz ?

An optical communication system, having an operating wavelength, lambda (in meters), can use only x% of its sourcefrequency as its channel band width.The system is to be used for transmitting TV signal requiring a band width of F hertz. How many channels can this system transmit simultaneously?

Optical communication system having an operating wavelength lambda metre can use only x % of its source frequency as its channel band width. The system is to be used for transmitting T.V signals requiring a band width of F hertz. How many channels can this system transmit simultaneously? Show graphically how this number of channels varies with operating wavelength of the system.
