Abstract

Conventional single-group optical orthogonal codes (OOC)-based optical code division multiplexing (OCDM) networks have been introduced and analyzed in some literature. To overcome the security restriction of single-group OOC-based OCDM networks, a new method for security improvement of OCDM networks is proposed, theoretically analyzed, and experimentally demonstrated for the first time in this work. A family of multiple-group OOC (MGOOC) is presented, and an example of a changing principle of the MGOOC is then considered in OCDM networks. Optical encoders and decoders for the MGOOC are designed and experimentally demonstrated successfully, and an OOC of the MGOOC is also selected randomly for any single user in this experiment. These results indicate that the new method for MGOOC-based OCDM networks is effective to enhance security performance.
