sorry biff44 i did't understand any thing, frankly i am not expert in optical fiber and i have no idea about it. so plz give me the receiver model which built by any software pleaaaaaaaaase help me.
Unless you know something about the block diagram you are trying to make, software would just be dangerous to you!
What are you transmitting (digital or analog signals)?
How far are you transmitting them?
Do you care about noise (time jitter, phase noise, AM noise, spurious)?
Cost?
How many are you making?
Any weird environment?
