Abstract

We propose a relatively simple solution that can compensate the signal attenuation due to stimulated Raman scattering cross-talk in a wavelength division multiplexed passive optical network (WDM-PON). The proposed solution also significantly increases the reach of the PON segment, enabling the merger of access and metro network boundaries. This can be accomplished using remote Raman amplification where a continuous wave counter-propagating pump is injected from one of the optical node units. A ~13 dB amplification of the downstream signal is observed with a bit error rate 1×10−12 for a 20-km fiber span. The reach of WDM-PON can be extended to ~40 km for typical 32 splits or up to 25 km for 64 splits using the proposed technique. We also report the effect of pump polarization on the amplification.
