Nokia and German service provider M-net have jointly announced the first field trial of probabilistically shaped wavelengths using Nokia Photonic Service Engine 3 (PSE 3) super coherent technology.  

In preparation for the roll-out of its state-of-the-art Bavarian WDM network, M-net has become the first carrier to trial Nokia's Photonic Service Engine 3 coherent digital signal processing technology. The PSE-3 is the first DSP to implement probabilistic constellation shaping, or PCS, a sophisticated signal processing technique pioneered by Bell Labs which finely adjusts the optical signal to maximize the data-carrying capacity of an optical fiber over any distance.  

M-net successfully transmitted 500G per wavelength over a deployed regional network, utilizing PCS to shape the signal from its maximum capacity of 600G to a rate optimized for the specific fiber route used in the test. This high level of performance and flexibility enables M-net to maximize the capacity of every network fiber, ensuring their innovative backbone will meet the demands of soaring video traffic and 5G mobile broadband. 

Dr. Hermann Rodler, CTO, M-Net
This field trial clearly underlines the innovative strength of M-net. We are very proud to collaborate with Nokia to push the technology envelope on our state-of-the-art fiber-optic network, and to be the first carrier to publicly test the PSE-3 and its probabilistic constellation shaping technology.

Sam Bucci, Head of Optical Networking, Nokia
The Technical University of Munich played a key role in the development of PCS, and the PSE-3 was largely developed at Nokia's R&D facility in Nuremberg, so it's only appropriate that the first field trial of PSE-3 technology would take place in Bavaria.
