Abstract
Bidirectional optical network based on direct detection optical code division multiple access (OCDMA) technique is implemented. In this architecture, in-band was used for up/downstream transmission data encoded by modified quadratic congruence (MQC) codes at channel spacing 12.5 GHz (i.e., 0.1 nm), and simultaneously transmitted since they are at different wavelengths. The results of the system with optimum parameters show low error rate transmission at 1 Gbit/s data rate and minimum receiver sensitivity −24 dBm which make the high performance is achievable. The results have indicated that bidirectional optical CDMA technique capable to support local area networks as an application for fiber to the home (FTTH).
