Abstract
Hybrid passive optical network (HPON) is one of ideal solutions for the next-gereration PONs with advantages of high capacity, long reach and single transport optical fiber. A novel wavelength division multiplexing (WDM) and time division multiplexing (TDM) hybrid PON architecture based on all-optical wavelength conversion (AOWC) technology is proposed. A novel burst-mode all-optical wavelength conversion module (BM-AOWCM) is developed for the critical system optical power budget, in which an Erbium-doped optical fiber amplifier (EDFA) and a gain-clamped wavelength converter based on a semiconductor optical amplifier (SOA) are employed. The degradation of the bit error ration (BER) of the EDFA and the AOWC are tested, respectively, which would limit the dynamic input power of the BM-AOWCM greatly. Experimental results indicate that the input dynamic range is extended from 5.5dB to 30dB at BER of 10E-9.
