Nokia launches OTN architecture for wholesale services

Nokia has announced a range of upgrades for its next-generation packet optical transport network (P-OTN) solutions used by CSPs offering wholesale services.

Upgrades to Nokia’s 1830 PSS-x solutions include a doubling of switching capacity up to 48Tb/s, new wavelength division multiplexing (WDM) uplinks based on Nokia’s fifth-generation Photonic Service Engines (PSE-V) and expanding the range of wholesale service options with new client interfaces supporting 400GE service transport, and a wide range of hard and soft isolation features for network slicing.

James Watt, head of optical networks division, Nokia, said, “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. 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.”

Alberto Maria Langellotti, head of IP, transport and SDN engineering, TIM Italy, explained how his company will use the upgrades. He noted, “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.”

OTN provides a unified networking technology to support a wide range of TDM and packet service and protocols such as ethernet, fibre channel and SONET/SDH. It has deterministic bandwidth and end-to-end management and supervisory capabilities, and bandwidth efficiency of non-blocking switching to maximise WDM uplinks between nodes.
