Demonstration of symmetrical 25 Gbps TDM-PON with 31.5 dB optical power budget using only 10 Gbps optical components

Abstract

First demonstration of symmetrical 25-Gbps TDM-PON with 31.5-dB class N2 power-budget over 0-20 km at 1556-nm using only 10-Gbps optical components. EDFAs are used as booster and preamplifier at the OLT. Low-cost dispersion compensating schemes are applied to increase reach.
