Abstract

We have studied distributed Raman amplification (DRA) and hybrid Raman amplification to apply both 10G-EPON and TWDM-PON systems. Two types of access networks, 50 km and 10 km, are assumed for case studies. Using the calculated optical received signal power Ps and optical signal noise ratio (OSNR), we consider the cases where the hybrid Raman amplification is necessary or not. In the case of coexistence of both systems, co-use of lumped Raman amplification (LRA) located at a central office (CO) may be possible. The co-use of LRA for both systems is discussed using the calculated Ps and OSNR.
