Where To Buy


The ET91000LCGB 1000 Mbps Gigabit Ethernet Multi Mode Fiber Media Converter LC 550m creates a simple, cost-effective Gigabit Ethernet-fiber link – transparently converting to/from 1000Base-T Ethernet, and 1000Base-SX optical signals to extend an Ethernet network connection over LC terminated multimode fiber at distances up to 550 meters (0.3 miles).

Easy to set up and install in a matter of seconds, this compact fiber media converter can be wall-mounted for out-of-the-way installations. The durable all steel chassis and heavy-duty power supply can withstand challenging industrial environments, and 6 integrated LED indicators make monitoring the Ethernet/fiber link easy.

This versatile GbE Ethernet to Fiber converter is compatible with most 3COM™, Cisco™, Lucent™ and Nortel™ networks and complies with applicable IEEE 802.3 standards.

Backed by a 2-year warranty and free lifetime technical support.
