Nokia reveals next-gen OTN architecture for wholesale
Nokia has announced a wide range of upgrades for its next-generation packet optical transport network (P-OTN) solutions for CSPs offering wholesale services.
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 can help CSPs scale networks with more capacity and new service options, while ensuring the ability to meet strict SLAs demanded by end users.
Upgrades to the 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 the Optical Networks Division at 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.’
