Nokia's 1830 PSS-x solution upgrades include doubling the switching capacity 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 that support 400GE service transport, as well as a wide range of hard and soft isolation features for network sharding.

According to Ian Redpath, Transport Networks Practice Leader at Omdia, coherent port bandwidth grew by 49% to reach 227 Pbps in 2021, providing significant opportunities for communications service providers to offer new services and increase revenue through wholesale service delivery. The wholesale business model can support end-to-end deterministic services across both traditional and emerging segments, such as mobile network sharding and backhaul, data center interconnection, wholesale transport for retail CSPs and enterprise customers, smart grids, and residential broadband backhaul, each with its own unique requirements for speed, latency, availability, and security.

Service providers must be able to 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 that ensures strong 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 they can meet the stringent SLAs required by end users.
