Agilent HFCT5611 GBIC-slot-equipped enterprise and carrier switches/routers Optical Transmission Module

The Agilent HFCT-5611 is a genuine 1000BASE-LX Gigabit Interface Converter (GBIC), a hot-swappable optical transceiver module used to add long-wavelength Gigabit Ethernet fibre ports to GBIC-slot-equipped switches and routers. Operating at a 1310nm wavelength over single-mode fibre with an SC duplex connector, this module is designed for longer-reach links than the equivalent short-wavelength SX variant, typically supporting distances of several kilometres depending on the fibre plant. GBIC modules of this family were widely deployed across enterprise and carrier switching platforms during the early Gigabit Ethernet era, and genuine, tested units remain a routine spares requirement for operators still running legacy GBIC-based chassis. This module supports restoring full port capacity after a failure, adding redundancy, or extending fibre reach on an existing deployment. Specifiers should confirm exact host-platform compatibility before ordering. Tech-Star (UK-based, shipped worldwide) stocks tested components to support ongoing network maintenance projects.
