Intelligent Burst Receiving Control in 100G Coherent PON with 4×25G TFDM Upstream Transmission

We proposed novel burst-receiving technologies, including power rebalancing and sub-channel recognition, in a 100G coherent PON with 4×25G-TFDM sub-channels. Superior burst-receiver performance is achieved over 80-km fiber with −39.2-dBm sensitivity and 2.4-GHz sub-channel frequency-detuning tolerance. © 2022 The Author(s)
