Source frequency ,v= c/lemda, where C is velocity of light and Lambda is wavelength .

bandwidth of system = x℅ of v = (x /100)v

= x/100 × c/ lemda

number of channels and which can be transmitted simultaneously can be found out by dividing bandwidth of the system with bandwidth of one channel .

N = (xc/100×lemda)/F

= xc/100 lemda F
