Nokia Photonic Service Engine (PSE)

2020: Announcement of Photonic Service Engine processors of fifth generation (PSE-V)

On May 28, 2020 the Nokia company provided products of the WaveFabric Elements family for fiber-optical networks with channels capacity to 400 Gbps (400G) and above, necessary for satisfaction of the growing demand for high-performance services of networks of mobile communication of the 5th generation (5G) and cloud networks.

Coherent digital signal processors of fifth generation Photonic Service Engine optimized for full-scale (end-to-end) implementation of optical links with capacity 400G and above on fiber-optical transport networks are a part of family.

The solutions of Nokia for fifth generation of the optical coherent digital signal processors (DSP) including the high-performance supercoherent PSE Vs Nokia processor and the economic compact PSE-Vc processor carry on tradition of development of the TsSP different models optimized for different optical network applications, design (form factor) and hardware platforms. Solutions TsSP are added now with a portfolio of the coherent optical products CSTAR which Nokia purchased together with Elenion Technologies company which is considered the pioneer in the field of optical silicon processor technologies.

Data transfer protocol application protocol Nokia

• PSE Vs Gbod provides digital signal processing with a character speed up to 90 and it is based on the technology of probabilistic formation of levels of optical power of points of the star chart (canstelletion) developed in Bell Labs Nokia at data transmission on optical link with high spectral efficiency using formats of modulation of QAM of different orders (probabilistic constellation shaping, PCS). It is the only PCS technology of the second generation in the industry which passed test in field conditions. The combination of advanced algorithms of signal processing to enhanced capabilities of digital signal processors of the next generation allows when using this solution to support on optical links of transport networks of transmission rate up to 800 Gbps (800G) at simultaneous increase in range of communication by 60%, reduction of energy consumption by 40% and increase in spectral efficiency for 15% in comparison with TsSP of the previous generations.
• PSE-Vc supports programmable data transmission with speeds from 100G to 400G and more on city and regional networks and also on backbone networks of big extent. The low power consumption allows to build in this solution the most different transceiving modules (transceivers).

The family of optical solutions of CSTAR is already delivered to customers. Platforms and devices with PSE-V processors will become available in the 4th quarter 2020.
