We present a self-coherent reflective PON demonstrator, TWDM-PON compatible, running at 10 Gbps upstream bit rate per ONU using commercial DFB lasers, achieving 31 dB ODN loss at BER=10−3 over splitter-based PON in TWDM-like burst mode operation.
A realistic uplink FDMA scenario for NG-PON2 is demonstrated with low speed electronics in the ONU (500 MHz) and high per wavelength aggregate capacity (12 to 15 Gbps). Stability over field deployed fiber is proven.
Some of the proposed NG-PON2 architectures encompass coherent receivers. In this scenario, we investigate the use of commercial DFB lasers, rather than more expensive ECL, showing negligible penalty for 40 Gbps PM-QPSK.
We present the first experimental demonstration of a Gigabit Ethernet transmission system capable of reaching 50m on A4a.2 POF (standard 1mm PMMA Step-Index Plastic Optical Fiber) with high system margin (6.5 dB) under real Ethernet traffic flowing between two workstations.
