Abstract

A detailed theoretical investigation of the cascadability of GC-SOAs and SOAs in WDM networks is presented. The analysis shows that the cascadability of SOAs is limited by degradation of both extinction ratio and ASE accumulation, whereas the cascadability for GC-SOAs mainly is limited by an accumulation af ASE. This result is superior cascadability of GC-SOAs at a channel bit rate of 2,5 Gbit/s in systems with up to at least 16 channels even when compared to short cavity SOA gates.
