Nokia PSE-6s optical networking equipment to cut 60% energy use

Nokia announced the launch of its sixth-generation super-coherent photonic service engine, the PSE-6s, promising to cut reducing network power consumption by 60 percent.

The PSE-6s supports the efficient delivery of high-speed services including 800 Gigabit Ethernet (GE), over distances of 2,000km and beyond.

Nokia will present PSE-6s for the first time at MWC 2023 in Barcelona and again at OFC in San Diego, next month.

Optical networking equipment containing the new PSE-6s is expected to be available for customer network trials in the second half of 2023.

Network capacity deployed over coherent optics is expected to grow at a rate of over 40 percent per year over the next four years, driven by more network connections, faster bandwidth speeds and new applications, according to research firm

Nokia PSE-6s optical engines support a unique chip-to-chip interface that enables them to be deployed in pairs to power the industry’s first 2.4Tb/s coherent transport solution. This allows network operators to efficiently transport any combination of high-speed client services including 400 and 800GE.

The telecom equipment maker said PSE-6s-enabled platforms offer three-fold increase in performance. Nokia said PSE-6s-enabled platforms support transport of 800GE services in metro and datacenter interconnect (DCI) applications, and with reach of 2,000km and beyond, across long-haul networks and trans-oceanic cables.

PSE-6s  integrates the latest generation of 5nm coherent digital signal processors (DSPs) with Nokia’s CSTAR silicon photonics. Operating at 130 Gbaud, the PSE-6s powers the next generation of coherent transport at up to 1.2Tb/s of capacity per wavelength.

PSE-6s offers a simple upgrade path for network operators, allowing them to upgrade their networks to PSE-6s across the 1830 family of optical networking platforms, including the 1830 PSS, 1830 PSI-M and 1830 PSS-x, leveraging existing ITU-T WDM channel plans.

“PSE-6s is available as an upgrade across our portfolio. Powerful enough to redefine the frontier of coherent transport, it’s nevertheless simple to deploy, so network operators can take immediate advantage of its scale and performance capabilities,” James Watt, Vice President Nokia Optical Networks, said.

“The 6th generation of coherent optical engines supporting 130Gbaud operation and up to 1.2Tb/s per wavelength gives us confidence to increase the capacity of Orange backbone networks in the future, running at 800Gb/s per wavelength in long distance links and providing a very efficient and reliable transport solution to interconnect our routers with 800GE ports,” Gilles Bourdon, Vice President Wireline Networks at Orange Group, said.

V.tal is a digital infrastructure company and holder of the largest neutral fiber optic network in Brazil, providing connectivity and digital solutions to telecom operators, ISPs and OTTs over backbone network with more than 400,000 km of fiber.

Cicero Olivieri, Vice President Engineering & CTO at V.tal, said: “We are excited with the potential of Nokia’s PSE-6s to provide efficient means to scale bandwidth, while also lowering power consumption, which is essential to meet our ESG commitments.”

“With its reduced power consumption per bit, PSE-6s will be instrumental to achieving our sustainability goals, supporting the UAE’s Net-Zero by 2050 ambitions,” Marwan Bin Shakar, Senior Vice President, Access Network Development, etisalat by e& UAE said.
