Title: How does passive optical network works?
Post by: neonix on October 22, 2024, 04:14:58 PM

I tried to find it out on Wikipedia but I don't find the answer. How it's possible to connect 32 users to one optic hub?

No, but here are 2 pdf files that are very informative.
The mystery was solved, and the answers are splitters and timeframes.

BTW. They can create Passive Optical Network where each user has its own laser color, and users at longer distance have stronger laser power. On short distance they can use LED instead laser. There is also problem with signal injection. It can be solved by using filter that pass-throuth only specific color.
