This compact networking device combines the functions of a copper-to-fiber media converter with that of a Gigabit-speed edge switch. Featuring the two 10-/100-/1000-Mbps copper switch ports and one 1000-Mbps single-mode fiber LC port, the Hardened Media Converter Switch reliably connects segments in harsh factory floor environments, particularly at the network edge, as well as connections in wiring closet and office areas. It''s just what you need to expand your Ethernet network in a convenient, compact, and economical way-plus transfer data longer distances, far beyond what''s possible with ordinary copper Ethernet cabling links. And because it transfers Ethernet packets at Gigabit speeds over fiber, you can ensure secure and interference-free extensions for your data-sensitive, bandwidth-intensive applications. What''s more, as a hardened networking solution, it features a sealed metal case that protects internal circuitry from dirt, dust, moisture, and other harmful contaminants. The Hardened Media Converter Switch also features an efficient thermal design, so no air inflow is required for cooling.
