Then the transmission of 10 Gbit/s FSK signal after a 50 km single mode fiber （SMF） was studied in this paper. The power penalty at the bit error rate （BER） of 10-9 was below 0.1 dB. The FSK modulation system can be applied to optical transmission system展开更多

A successful cost effective colorless WDM-PON full duplex transmission operation for a data rate of 10Gbps per channel, with a channel spacing of 60 GHz over a distance of 25 km without any optical amplification and dispersion compensation is achieved within low power penalty.展开更多
