Abstract :
A next generation passive optical network (NG-PON) becomes necessary to upgrade the systems, providing a larger dedicated bandwidth to each user. Optical code division multiple access (OCDMA) is one promising candidate for the NG-PON technique with unique features of full asynchronous transmission, low latency access, soft capacity on demand as well as optical layer security. Recently, a cost-effective OCDMA system using a single multi-port en/decoder at an optical line terminal (OLT) and superstructured fiber Bragg grating (SSFBG) encoder/decoders at each optical network unit (ONU) in an optical network has been proposed and demonstrated. In this paper, we review a full-duplex, 10 Gbps, asynchronous DPSK-OCDMA system including hybrid multi-port and SSFBG encoding/decoding devices and recent demonstrations.
