Nokia introduced its sixth-generation super-coherent photonic service engine, enabling efficient delivery of 400G to 800 Gigabit Ethernet over distances of 2,000km and beyond.
Nokia’s PSE-6s, which integrates the latest generation of 5nm coherent digital signal processors (DSPs) with Nokia’s CSTAR silicon photonics, operates at 130 Gbaud for coherent transport at up to 1.2Tb/s of capacity per wavelength. The PSE-6s optical engines support a unique chip-to-chip interface that enables them to be deployed in pairs for 2.4 Tb/s coherent capacity, supporting any combination of high-speed client services including 400 and 800GE.
Nokia says this next generation photonic service engine provides an economic case for 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. In terms of energy efficiency, the PSE-6 promises network power reduction of up 40% per bit transported.
Significantly, the PSE-6s cards can be deployed across the company’s existing 1830 family of optical networking platforms, including the 1830 PSS, 1830 PSI-M and 1830 PSS-x, leveraging existing ITU-T WDM channel plans.
James Watt, Vice President Nokia Optical Networks, said: “Additional capacity often means additional complexity for operators. But PSE-6s is designed to make scale simple. 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. What’s more, these benefits come with lower power consumption per bit, resulting in a better TCO, as well as helping operators meet increasingly aggressive carbon reduction targets.”
Gilles Bourdon, Vice President Wireline Networks at Orange Group, 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.”
Cicero Olivieri, Vice President Engineering & CTO at V.tal, said: “As 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 our unique nationwide backbone network with more than 400,000 km of fiber, a key priority for V.tal is to scale our infrastructure and support new high-speed services such as 400GE/800GE to accommodate the growing demand. 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.”
