Abstract

We report a 2:1 rate asymmetric high serial rate TDM-PON with single carrier 25Gb/s upstream and 50Gb/s downstream. In the upstream, we present a first 25Gb/s 3-level modulated BM-RX employing a 1/4-rate linear BM APD-TIA and a custom decoder IC. We successfully demonstrated burst-mode sensitivity of −20.4 dBm with 18 dB dynamic burst-to-burst for 25Gb/s upstream links. In another direction, a downstream in upper O-band is proposed and demonstrated with 3-level duobinary modulation at 50Gb/s in real-time. The upstream and downstream transmission experiments show that the proposed asymmetric 50G/25G high serial rate TDM-PON can support 32 users while covering more than 20 km reach.
