1.3 / 1.5 µm QD-SOAs for WDM/TDM GPON with extended reach and large upstream / downstream dynamic range

GPONs with extended reach require 1.3 mum and 1.5 mum amplifiers for up and downstream, respectively. Burst-mode compatibility and largest possible input power dynamics are necessary. We show that latest-generation QD-SOAs fulfill these demanding specifications.
