摘要
This paper investigated the impact of Rayleigh backscattering （RB） noise in the proposed wavelength- division-multiplexed （WDM） single-fiber loopback access network. RB noise＇s impacts on the downstream and upstream service were discussed in details. It was found that the receiver sensitivity was less sensitive when the seeding-light power was below - 12.6 dBm. And for the uplink RB noise, a higher reflective semiconductor optical amplifier （RSOA）＇s bias current results in lower receiver sensitivity.
