Abstract :
The effect of SRS crosstalk in PON has been reported in several papers. In this paper, we propose a solution that can be used to compensate the signal attenuation due to SRS crosstalk. Proposed solution can also be used to increase the reach of PON, in an effort to merge access and metro networks. This is done by using remote Raman amplification where, a CW counter-propagating pump is placed at one of the ONUs. A ~15 dB amplification of the downstream signal is observed with a BER < 10e-12.
