摘要：

We experimentally demonstrate a 10 Gb/s bidirectional subcarrier multiplexed (SCM) wavelength-division multiplexed (WDM) passive optical network (PON). We use digital signal processing and square-root raised cosine pulse shaping techniques to generate M-ary quadrature amplitude modulation electrical signals for the downlink and uplink transmissions using simple intensity modulation and direct detection optoelectronics, and 10 GHz transceivers. The design includes spectral pre-emphasis and offset optical filtering to increase the effective bandwidth of a commercial 2.2 GHz reflective semiconductor optical amplifier based optical network unit. We realize symmetric 10 Gb/s transmission over a 20 km single feeder PON with optical line terminal launch powers from 1 to 9 dBm. We also demonstrate the ability of these SCM WDM PONs to withstand the effects of upstream impairments.
