Abstract

Bidirectional HDTV/Gigabit Ethernet/CATV over hybrid dense-wavelength-division-multiplexing passive optical network (DWDM-PON) based on injection-locked vertical cavity surface emitting lasers (VCSELs) and distributed feedback (DFB) laser diodes as transmitters were proposed and demonstrated. Services with 129 HDTV channels, 1.25 Gb/s Gigabit Ethernet connection, and 77 CATV channels were successfully demonstrated over 40 km single-mode fiber (SMF) links. Good performance of bit error rate (BER)/carrier-to-noise ratio (CNR)/composite second order (CSO)/composite triple beat (CTB) were achieved in our proposed bidirectional DWDM-PON.
