Nokia launches next-gen coherent optics, reduces network power consumption
Nokia unveiled its sixth-generation photonic service engine (PSE-6s), promising up to 60 percent reduction in network power consumption per bit and supporting 1.2 terabits per wavelength.
Nokia Oyj launched its sixth-generation super-coherent photonic service engine (PSE-6s) on Thursday at the MWC event in Barcelona. The company claims the new technology can reduce power consumption in optical transport networks by up to 60 percent per bit.
The new PSE-6s chip enables data transmission speeds of 1.2 terabits per wavelength and supports data transmission solutions of up to 2.4 terabits through a chip-to-chip interface. This addresses the growing demand for data traffic and allows for the efficient transport of 800 Gigabit Ethernet (GE) services over distances of up to 2,000 kilometers.
The technology integrates the latest generation of 5nm coherent digital signal processors (DSPs) with Nokia's CSTAR silicon photonics. Industry analysis firm Cignal AI projects that optical transport capacity will grow by over 40 percent annually over the next four years. The PSE-6s is designed to meet this demand while reducing network energy consumption.
Nokia is offering the PSE-6s as an upgrade for its existing 1830 series of optical networking hardware. The company states that the new technology significantly enhances performance and reach compared to previous generations, supporting sustainable network evolution and assisting operators in achieving their carbon emission reduction targets.
