Abstract

We propose a novel, simple, and cost-effective technique to decrease beat noise in standard one-dimensional (1-D) optical coding passive optical networking (PON) monitoring. This scheme places low-cost 1-D encoders at the termination of the network branches and two-dimensional (2-D) decoders at the central office mixing the 1-D and 2-D schemes in a complementary way. Simulation shows that our proposed scheme allows the monitoring of a 64 customer PON with a signal-to-noise ratio of 9.1 dB.
