Nokia has taken the wraps off its fifth-generation IP routing silicon. Appropriately called the FP5, the silicon is designed to support 800 Gigabit Ethernet (GbE) interfaces as well as improved security through flow-based encryption, while offering a 75% reduction in power and a new embedded line rate.The FP5 will enable Nokia service router platforms to support high-density 800GbE and 1.6-Tbps clear channel routing interfaces. (The company has already conducted terabit clear channel tests based on the previous FP4 chipset; see “Nokia, Vodafone Turkey trial intercontinental 1-Tbps clear-channe...

The Ethernet Alliance's High Speed Plugfest series is back up and running after a COVID-induced break.After a COVID-induced hiatus, the Ethernet Alliance has resumed its series of High Speed Networking Plugfests at the University of New Hampshire’s InterOperability Labs (UNH-IOL; see, for example, 'Latest Ethernet Alliance High-Speed Networking Plugfest has 97% pass rate'). The most recent edition, held April 24-29, 2022, brought together 18 member companies to evaluate the state of 100-Gbps and electrical lane support within the context of IEEE 802.3ck and 50-Gbps within IEEE 802....
GTT Communications, Inc. says it will upgrade its global Tier 1 IP network with 400G transmission capabilities. The connectivity provider says the enhancement will enable it to deal with double-digit increases in IP traffic while improving network scalability and the ability to offer higher-capacity options for GTT’s suite of enhanced internet and WAN services.The phased rollout will focus initially on metro city locations and expand to GTT’s core IP switching and routing fabric that links more than 260 cities on six continents. GTT expects to finish the initial upgrade phase during the second...
Nokia says it has completed a successful 600-Gbps transmission trial with Italy’s TIM. The trial included the transmission of 600 Gbps over a 1008-km link within TIM’s terrestrial fiber backbone network.The trial used fielded colorless, directionless, and directionless flexible-grid ROADMs from Nokia (specifically, 1830 PSI-M compact modular disaggregated transport systems) that TIM is using for its backbone infrastructure. The ROADMs were equipped with the technology vendor’s PSE-Vs super coherent optics. The 600G transmission leverage 100-GHz channels and produced a spectral efficiency of 6 ...
