Improved performance analysis of Gigabit passive optical networks

Abstract

Gigabit passive optical networks (GPON) provide a capacity boosts in both the total bandwidth and bandwidth efficiency through the use of larger variable-length packets in Passive Optical Networks technology. In this paper, we have described a purely-passive GPON compatible reach extender using distributed Raman amplification and reported the improved investigation through implementation of a square root module by a distance of 60km at data rate of 2.5Gbps. An efficient improvement in Q factor is achieved with square root module, which further helps in increasing the length of GPON.
