An 8- × 10-Gb/s 42-km High-Split TWDM PON Featuring Distributed Raman Amplification and a Remotely Powered Intelligent Splitter

摘要

We demonstrate an intelligent symmetric-rate 8- × 10-Gb/s bidirectional time and wavelength-division multiplexed passive optical network with 42-km reach and 1:256 split 1425-nm laser pump light provides distributed Raman amplification for the upstream channels (allowing low-cost low-power transmitters), serves as a low-rate telemetry channel, and powers an intelligent splitter module that provides supervision for mission-critical services
