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

This is close to the theoretical maximum information transfer rate of that channel and thus approaching the Shannon Limit
of the fiber link.
The purely digital multifunctional receiver is targeted for end-applications such as combat-radio and radio-relay, providing robust communication at lowsignalto-noise ratio with performance approaching the Shannon limit
(Fagoonee & Honary, 2004).
Near Shannon Limit

In the lab, we're there" at the Shannon limit
, says Robert McEliece, a coding theorist at the California Institute of Technology in Pasadena.
Instead, their effects are lumped into a technology-based parameter [alpha], which measures how closely the Shannon limit
on spectral efficiency is achieved.
It is well known that the capacity of a communication channel is constrained by the Shannon limit
NEC breaks world record for spectral efficiency, close to Shannon limit
709 standard, nearly reaching the theoretical maximum defined by the Shannon Limit
Using the MIMO-SDM technique, Bell Labs aims to overcome the capacity limitations imposed by the non-linear Shannon limit
on current optical fiber.
