Nokia has announced a wide range of upgrades for its next-generation packet optical transport network (P-OTN) solutions needed by CSPs offering wholesale services.
Nokia says the upgrades to its 1830 PSS-x solutions include a doubling of switching capacity up to a market-leading 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.
According to Omdia practice leader for transport networks Ian Redpath coherent port bandwidth grew by 49% to 227 Pbps in 2021, providing significant opportunities for Communication Service Providers to offer new services and grow revenue through wholesale service delivery. The wholesale business model can support deterministic end-to-end services across both traditional services and new segments such as mobile network slicing and backhaul, data centre interconnect, wholesale transport for retail CSPs and business customers, smart power grids and residential broadband backhaul, who all bring their own requirements in speed, latency, availability and security.
Nokia says that service providers need to be able to easily scale capacity and support a wide range of existing and emerging protocols, while delivering guaranteed service level performance and security over a shared network infrastructure. OTN uses a digital wrapper to encapsulate TDM and packet services, providing a robust and efficient transport protocol ensuring hard isolation between different users across a common infrastructure. This proven optical transport technology helps CSPs scale their networks with more capacity and new service options, while ensuring the ability to meet strict SLAs demanded by end users.
Nokia head of optical networks division James Watt 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.”
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, with deterministic bandwidth and end-to-end management and supervisory capabilities, and bandwidth efficiency of non-blocking switching to maximise utilisation of WDM uplinks between nodes, the company stated.
Nokia says it continues to lead the industry in expanding capabilities across its portfolio of 1830 PSS-x P-OTN solutions for metro, regional and long-haul core networks, including:
- Doubling non-blocking switching capacity, up to 4Tb/s in the PSS-8x, 12Tb/s in the PSS-12x, and up to 48Tb/s in the PSS-24x
- Support for new WDM uplinks based on Nokia’s fifth-generation Photonic Service Engines, including 90Gbaud super coherent optics (PSE-Vs) and 400G pluggable digital coherent optics (PSE-Vc)
- 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
Global Connect head of optics Jan Flemming Henriksen said: “By using OTN switching, we are able to offer our customers high capacity 400GE DCI services, while also improving our ability to support our classic low capacity services in the future, with new high availability options, increasing the service reliability.”
Swisscom product manager optical transport Wilfrid Puyo said: “Nokia’s OTN architecture and WaveSuite automation tools help us efficiently deliver existing 100Mb links in large numbers, and soon expand that to 400Gb links to meet the rising traffic demand for our fixed-mobile convergent networks, while guaranteeing our customers the level of service they demand with relative ease.”
Nokia added that these new capability enhancements to the 1830 PSS-x portfolio interwork seamlessly with the 1830 ONE and 1830 PSD compact solutions to enable service providers to deliver end-to-end high-capacity services from the metro/edge through national and global core networks. Together, Nokia’s complete portfolio of scalable and application-optimised P-OTN solutions provide a complete, flexible and efficient network ready to deliver any service today and into the future.
