Title:
OPTICAL CODE DIVISION MULTIPLEX ACCESS SYSTEM
Document Type and Number:
Japanese Patent JP2009200733
Kind Code:
A
Abstract:
To provide a versatile optical code division multiplex access system (OCDMA).
The optical code division multiplex access system 5 has a central station 2 provided with a multi-port optical coder 1 and a decoding part 4 provided with a decoder 3 for decoding optical signals coded by the multi-port optical coder 1. Then, the multi-port optical coder 1 converts the input optical signals to the coded optical signals whose wavelength is different by a prescribed amount for each code pattern. The decoder 3 is a superstructured fiber Bragg grating SSFBG having a center wavelength corresponding to the coded optical signals.
