Multiuser asynchronous OCDMA system with different types of FBG based en/decoders

Asynchronous OCDMA systems are demonstrated using 511 chip, 640 Gchip/s and 31 chip, 40 Gchip/s with different types of fiber Bragg grating encoders/decoders. Error-free transmission has been achieved with up to five OCDMA users.
