security in optical networks
The attachment here shows an Add drop function using Fiber bragg grating..when i transmit data, the signal shows fine upto fiber bragg grating…however when i check my signal (reflected wavelength) from the grating after bidirectional fiber, there is no signal response..Please can someone help me in finding whats wrong or if i am doing something wrong..! i would appreciate the responses
