Hello all,
I am having an assignment in designing WDM PON,they have given that connect optical delay between AWG and bidirectional fiber.
In optisystem tutorial,they have used optical delay before and after the bidirectional fiber. link is here.
Broadband Optical System Based on a Passive Optical Network (BPON)
What is the difference between connecting optical delay before and after the bidirectional fiber and connecting optical delay between AWG and bidirectional fiber?
Why buffer selector is used in the tutorial?
Thanks in advance.
