Nokia and German service provider M-net are laying claim to the industry's first transmission of a probabilistically shaped wavelength.

M-net is the first carrier to trial Nokia's Photonic Service Engine 3 (PSE-3) coherent digital signal processing technology. Nokia said the PSE-3 is the first DSP to use probabilistic constellation shaping (PCS). PCS is a signal processing technique pioneered by Bell Labs that adjusts the optical signal to maximize the data-carrying capacity of an optical fiber over any distance, according to Nokia.

The field trial was conducted over a regional DWDM network spanning Bavaria as M-net prepares for the commercial roll out its new WDM network. M-net and Nokia hit 500 gigabits per second over a single probabilistically shaped 64-QAM wavelength in a real-world environment for the first time.

Blitz Week

Register for FierceTelecom Blitz Week - June 15-18

As the telecom industry moves forward in the age of new technology, FierceTelecom Blitz week addresses the questions of how platforms, providers, and more will modernize to keep up with these fast-paced changes and their current status of implementing these changes. Join us June 15-18 to dive deep into the world of telecom transformation.

M-net used PCS to shape the signal from its maximum capacity of 600G to a rate optimized for the specific fiber route used in the test. The high level of performance and flexibility enabled M-net to maximize the capacity of every network fiber, ensuring its backbone will meet the future demands of increased video traffic and 5G mobile broadband.

"We're excited to partner with M-net on the implementation of its new fiber optic backbone network," said Nokia's Sam Bucci, head of optical networking, in a statement. "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."
