Support beyond manufacturer change

Protect the Coriant network you still rely on.

Coriant became an independent company in 2013 following its separation from Nokia Siemens Networks. Its portfolio later brought together optical networking technologies associated with Siemens, Sycamore and Tellabs before Coriant was acquired by Infinera in 2018.

These platforms continue to perform important transport roles in operational networks, but changing OEM ownership, mature hardware and reduced access to specialist skills can make long-term support more difficult.

Carritech provides an independent support route that helps organisations source Coriant hardware, repair failed equipment, resolve complex faults and plan future migration on their own timetable.
