Nortel FA18UFDC Type-119 18dBm erbium-doped fibre amplifier (EDFA), DC-powered, front fibre exit.
The Nortel FA18UFDC is an 18dBm erbium-doped fibre amplifier (EDFA), part of Nortel’s Type-119 optical amplifier subrack system used in DWDM transmission networks.
In the Type-119 naming scheme, ‘F’ denotes a front-mounted fibre exit and ‘DC’ denotes a 48V DC-powered rack variant, distinguishing it from the AC-powered FA17UFAC-series units in the same family. The amplifier boosts optical signal power across long-haul or metro fibre links, and is managed through the subrack’s front-panel and remote/local serial communications interfaces.
The FA18UFDC is specific to Nortel’s Type-119 optical transmission subrack platform. Tech-Star (UK-based, shipped worldwide) checks every amplifier before it ships. Get in touch to confirm compatibility with your Type-119 subrack.
