Orange successfully tests Fujitsu 1FINITY T900 transponder for optical transport

Fujitsu announced that Orange S.A., a global communications service provider, completed a lab evaluation of the Fujitsu 1FINITY T900 Series Transponder at Orange Innovation Labs in Lannion, France. The trial tested the transponder’s performance at 800 Gbps wavelengths over a distance of at least 1,600 km, with power consumption below 150 Watts.
The evaluation showed that the 1FINITY T900 maintained consistent power consumption across all transmission rates, supported by Fujitsu’s closed-loop liquid cooling technology. The transponder supports up to 1.2 Tbps per wavelength and enables increased spectral efficiency for long-haul transport. Orange aimed to address rising data demands and high energy costs while meeting sustainability goals by reducing power consumption.
The trial results indicated potential for extended long-haul transport distance and capacity without increased power consumption. Fujitsu will establish 1FINITY Inc. on July 1, 2025, to consolidate its network business products and operations, focusing on optical and wireless solutions.
