Abstract

A cost-effective filterless coherent receiving architecture is proposed using single-ended photodiodes. By dedicating two additional direct detection signal lanes to reject signal-signal interference in the digital domain, we successfully achieved the reception of 80×112-Gb/s WDM channels after 2000-km transmission with only 1.7-dB Q penalty.
