The chipset is the maiden to include the probabilistic constellation shaping (PCS) technique founded by Nokia Bell Labs, which has the potential to push fiber performance close to the Shannon Limit.
There is more than one way to design modulation formats that can get close to the Shannon limit in the linear regime, however, most of them do not fare well when operated in the nonlinear regime, where they suffer more performance gap towards the nonlinear Shannon limit.
