Orange and Nokia tested chipsets of Photonic Service Engine on the working all-European network

2020: Tests of chipsets of digital signal processors of fifth generation of Photonic Service Engine Nokia

Orange and Nokia announced on July 14, 2020 end testing of chipsets (GSI) of digital signal processors (DSP/TsSP) of fifth generation of Photonic Service Engine NOKIA (NOKIS PSE-V) during transfer of traffic on the operating network of Orange operator.

The technology will allow to treble capacity of backbone optical transport networks of big extent.

Among advantages of this technology and possible applications it should be noted a possibility of providing network services (connections) with big capacity over backbone optical transport networks of big extent and ensuring broadcasting broadcast of sports competitions in real time.

Were tested within three weeks on the all-European extended trunk optical transport infrastructure of Orange International Networks Infrastructures and Services (OINIS) without interruption in provision of services and transfer of normal commercial traffic. Test traffic was transferred from the Parisian network point to 15 points of presence (PoP) with a speed of 400 Gbps on distance to 3400 km. Thus, this solution allows to provide transfer of high-speed traffic without intermediate OEO (Optical – Electrical – Optical) to regeneration from Paris in any point in the territory of Europe and even beyond its limits. Besides, as a result of tests the possibility of the organization of optical links (lengths of waves) with capacity to 600 Gbps with spectral efficiency more than 6 Gbit/sec./Hz on distance more than 1000 km is confirmed. This achievement opens opportunities for mutual connection of the European data processing centers (DPC) and their integration with global underwater fiber-optical cable systems. On one fiber optic pair, for example, on section between Paris and Leon, the general capacity of a transmission system up to 27 Tbit / page can be reached.

The technology gives the chance to treble the capacity of long distance communication channels and to reduce energy consumption thanks to implementation of high character speed and effective probabilistic processing of PCS (Probabilistic Constellation Shaping) of points of the star chart of a line signal with a modulation QAM format when preserving by 50% the existing, having high flexibility and aiming at perspective solutions, network infrastructure.

We continuously estimate technology achievements of our equipment suppliers and solutions (vendors) in real vital scenarios that each technology achievement gave to our customers real advantages. Chipsets of fifth generation seem to us very attractive. They allow to take a step to creation of more effective, economic and eco-friendly network. Moreover, integration of this network with underwater cable systems will allow to cover the whole world.

We with showed and checked in practice chipsets of fifth generation and probabilistic algorithms of PCS 2.0 in OINIS network. These tests proved realness of our strategy which is directed to optimization and harmonization of such parameters as spectral efficiency, communication range, energy consumption and total cost of ownership. As a result we can claim that such transmission rates as 400 Gbps at long distances and 600 Gbps at the regional level are quite achievable.

Chipsets of generation of NOKIA PSE-V reduce the need for installation of active network equipment on route of extended high-speed connection (optical link) on trunk and regional networks. They increase the general reliability of long distance communication channels and increase service quality thanks to more perfect algorithms and also use of telemetry and artificial intelligence.
