Multi-Rate 25/12.5/10-Gb/s Burst-Mode Upstream Transmission Based on a 10G Burst-Mode ROSA with Digital Equalization Achieving 20dB Dynamic Range and sub-100ns Recovery Time

We experimentally demonstrate multi-rate burst-mode transmission at 25, 12.5 and 10Gb/s using a 10GHz-class burst-mode receiver optical sub-assembly (ROSA), respectively achieving receiver sensitivities of −27.7, −31, and −32.1dBm after 20-km SSMF transmission at 1E-2 BER, all with 20-dB dynamic range and 92-ns burst recovery time.
