1FINITY™ T900 transponder

Flexible, sustainable long-haul networking

The 1FINITY T900 liquid-cooled transponder delivers the highest long-haul transport performance at the lowest cost, in a future-ready platform that is simple to operate and maintain. The T900 is a compact, modular platform that offers new sustainability features to support service providers in reducing carbon footprint.

The system provides a total maximum capacity of 14.4T while consuming up to 70% less power than the previous generation of 800G blades and supporting over 2400 km reach. This 2RU compact, modular blade includes a field-replaceable Management Control Unit (MCU) for standalone or aggregator management, as well as sustainable thermal management using liquid cooling and a field-replaceable fan/pump unit.
