Ring-Based WDM-PON with Suppression of Rayleigh Backscattering Interferometric Noise
暂无分享,去创建一个
We demonstrate a ring-based WDM-PON. Rayleigh-backscattering (RB) can be suppressed since the upstream signal and the RB are traveling in different directions. We also analyze the network performance when upgrading to 40-Gb/s. ©2011 Optical Society of America
