The PSE-3 maximizes performance at any possible distance within an optical network. Offering powerful programmability, it enables you to move beyond the limited flexibility of 100G/200G networks and build a highly scalable, automation-ready network.
PSE-3 provides finely adjustable wavelength capacity from 100G to 600G with a single, uniform modulation format and channel size. This simplifies network operations and planning and facilitates the dynamic operations you need to deploy innovative services and lower your costs.
With PSE-3, you can get new levels of competitive potential from your network. You can meet growing bandwidth demands by automatically optimizing wavelength performance over any route. And you can do it while reducing total cost of network ownership.
The Shannon limit defines the maximum amount of information that can be transmitted over a given communications channel. The limit was defined in 1948 by Claude Shannon, a researcher at Bell Labs.
Probabilistic constellation shaping (PCS) is a new wavelength modulation technique that pushes optical wavelength performance up against the Shannon limit. It enables you to deliver the highest possible network capacity over any distance.
PCS intelligently shapes the signal constellation to perfectly match the optical characteristics of each wavelength route. It improves optical reach and performance to within a fraction of a dB of the Shannon theoretical limits while enabling a previously unachievable degree of bandwidth granularity efficiency.
