This Gigabit Ethernet to SM Fiber converter lets you extend a Gigabit Ethernet network over single mode fiber, at distances up to 40km (25 miles). Providing a cost-effective solution for connecting a Gigabit Ethernet network to remote network segments over a fiber backbone, the GbE to SM fiber converter supports full Gigabit speeds end-to-end and delivers ideal network performance and scalability. The Gigabit Ethernet/Fiber converter transparently converts 1000Base-T Ethernet into 1000Base-LX/SX optical for long distance single mode fiber connection to a second Gigabit Ethernet/SM Fiber converter, which performs the reverse operation (converting the 1000Base-SX/LX signal back into 1000Base-T) for connection to the remote Gigabit node/segment. Designed to offer a durable and convenient Ethernet to fiber solution, the Gigabit Ethernet to SM Fiber converter features an all-steel chassis, and can be wall-mounted for out-of-the-way installations.
