Improving the performance of OADM subsystem using pre-EDFA

Optical add/drop multiplexers (OADM) can play an important role in WDM optical transport network systems. In this paper, we focus on the performance of using OADM integrated with pre-EDFA in multi-wavelength optical transmission networks called OADM subsystem. We calculate the receiver sensitivity incurred in an OADM subsystem with pre-EDFA. We theoretically investigate the effects of the spontaneous emission factor, and pre-amplifier gain, spontaneous emission factor, on the receiver sensitivity. The theoretical results agree well with the experimental results we have done.© (2001) COPYRIGHT SPIE--The International Society for Optical Engineering.
