Hi Alistu,
You are right about the access scheme adopted for our system but think this way that i am transmitting data in optical network and in optical network our data is modulated on light so if anyhow the attacker gets access to some component where he can make sure he can insert a malicious signal into the light stream or is able to receive the light pulses he can can get the information. So keeping this insertion and reception in mind can you suggest a component. For reception i guess splitter will help me. Now i want a component that could help me in insertion of light into the system.
Regards
