Demonstration of using injection-locked Fabry-Pe?? rot laser diode for 10 Gbit/s 16-QAM OFDM WDM-PON

摘要

A 10 Gbit/s OFDM upstream transmission has been investigated by using a Fabry-Pe??rot laser diode (FP-LD) based ONU with seedinglight in a colourless WDM-PON. Also demonstrated is the relationship of CW injection power and SNR of each OFDM subcarrier for a mode-locked FP-LD. Moreover, when a 16-QAM OFDM modulation is applied in a modelocked FP-LD, -15.7 dBm received sensitivity at the BER of 3.8 X 10-3 can be obtained after 20 km fibre transmission.
