This Gigabit Ethernet Media 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 Gb E to SM fiber converter supports full Gigabit speeds end-to-end & delivers ideal network performance & scalability. The Gigabit Ethernet/ Fiber converter transparently converts 1000 Base-T Ethernet into 1000 Base-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 1000 Base-SX/LX signal back into 1000 Base-T) for connection to the remote Gigabit node/segment. Designed to offer a durable & convenient Ethernet to fiber solution, the Gigabit Ethernet to SM Fiber converter features an all-steel chassis, & can be wall-mounted for out-of-the-way installations. Please note: networking components such as switches, routers, UPS & wireless devices require that speeds & standards be consistent throughout the network to gain optimum performance.
