ok Alistu
thanx a lot for your help.
here is a new question i wanted to ask about the component ‘fork’ used in optisystem. what is the exact function of the fork. in the ‘help’ about the fork, it is written that it copies the input to multiple output port, but i have a doubt here, if the fork copies the input to the output, then the power of each signal at the output should be same as the input signal , i am attaching a screenshot of a system, refering to that….how can we give one signal of a particular power at the input and rceive many signals of the same power at the output????
is there some power multiplier or something like that present in the fork.
