Coherent PON for NG-PON2: 40Gbps Downstream Transmission with 40dB Power Margin using Commercial DFB Lasers and no Optical Amplification
We demonstrate a 40Gbps downstream PON
transmission based on PM-QPSK modulation using commercial DFB
lasers without optical amplifier in the ODN, obtaining 40dB power
budget. We discuss this solution within NG-PON2 architectures.
