Nokia upgrades 1830 PSS-x line of packet OTN platforms
Nokia says it will upgrade its 1830 PSS-x line of packet Optical Transport Network (P-OTN) systems to better support the delivery of wholesale services. The enhancements include doubling switch capacity (up to 48 Tbps on the largest on the 1830 PSS-x platforms), new WDM uplink support based on Nokia’s Photonic Service Engines (PSE-V) that includes 400 Gigabit Ethernet (400GbE) coherent transport capabilities, and hard and soft isolation features for network slicing.
The capacity upgrades include up to 4 Tbps in the PSS-8x, 12 Tbps in the PSS-12x, and up to 48 Tbps in the PSS-24x. The 400GbE coherent transmission capabilities derive from the use of 90-Gbaud super coherent optics based on Nokia’s PSE-Vs coherent engine and 400G pluggable digital coherent optics equipped with the PSE-Vc.
Nokia says that the upgrades will help communications services providers (CSPs) address new wholesale opportunities across multiple service types thanks to the capabilities of OTN. “We are excited to offer advanced capacity scaling and extended service offerings to our 250+ 1830 PSS-x customers, while also enabling new service capabilities across the entire CSP wholesale market,” commented James Watt, head of the Optical Networks Division at Nokia. “Our new upgrades provide comprehensive options for flexible OTN switch fabric capacity scaling, support higher speed line interfaces, provide new wholesale services, and enable hard traffic isolation, all critical features for a composable and future-proof network.”
Representatives from such CSPs as Global Connect, Swisscom, Telefonica Spain, and TIM Italy provided quotes for the announcement of the new capabilities that attested to the benefits they see in OTN. “We see a great opportunity in using OTN as it enriches the value of our already performing photonic network, enabling the support of premium services for wholesale service providers and enterprises, ensuring to our customers high service level performance and security, as well as providing an efficient and scalable way to support TDM service replacement,” said Alberto Maria Langellotti, head of IP, Transport & SDN Engineering, TIM Italy, for example.
