The shape of things to come

Meet surging video, cloud and 5G traffic demands by using our super coherent Photonic Service Engine 3 (PSE-3) chipset to maximize the capacity and performance of every link in your optical network.

The PSE-3 implements probabilistic constellation shaping (PCS) to maximize capacity over any distance and on any fiber — from metro to subsea. A concept pioneered by Nokia Bell Labs, PCS pushes optical performance up against the Shannon limit, the maximum possible information transfer rate.

PSE-3 is ideal for service providers and webscale companies looking to push the limits of their optical networks and increase the returns on their fiber investments.

How PSE-3 reshapes optical networks

  • Provides the first implementation of PCS, pushing fiber-optic performance close to theoretical limits at any distance — from 10 km to 10,000 km and beyond
  • Increases capacity up to 65 percent over commonly deployed networks while reducing power usage per bit by 60 percent
  • Automatically optimizes network capacity and reach with a new level of granularity efficiency
  • Improves optical wavelength performance by up to 25 percent compared to today's most advanced systems
  • Drives down operational complexity with simplified spectrum planning and automatic wavelength optimization

Performance with simplicity and insight

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.


What can PSE-3 do for you?

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.

What limits us, inspires us

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.
