[Whitepaper Download] By Infinera: Faster, Further, Smoother: The case for probabilistic constellation shaping

jessica Uncategorised Leave a Comment

Overview: Conventional coherent modulation based on quadrature amplitude modulation (QAM) has limitations related to granularity, reach, and baud rate flexibility. A new modulation paradigm, probabilistic constellation shaping (PCS), promises to address these limitations while taking us to within touching distance of the Shannon limit, the theoretical maximum data capacity for a given amount of spectrum in the presence of noise.

Summary: Since its emergence in the late 2000s, coherent technology has undergone several transitions. First it went from 40G to 100G, then from hard-decision forward error correction (FEC) to soft-decision FEC, and finally from single-rate interfaces to flexible-rate interfaces with additional modulation schemes such as 8QAM (150 Gb/s) and 16QAM (200 Gb/s). With no end in sight to the traffic growth …

Summary: A wide range of cloud and video applications, together with the increased access speeds enabled by 5G, DAA, and next-generation PON, are driving the need for ever more optical bandwidth. To deliver this bandwidth, optical vendors are developing a broad range of coherent optical transceivers addressing different segments of the market, each with its own set of design considerations. …
