Omnitron Systems Miniature 10/100BASE-TX to 100BASE-FX Ethernet Media Converter - 1 x Network (RJ-45) - 1 x SC Ports - 0.1 mil Fiber - 10/100Base-TX, 100Base-FX - 5 km - Wall Mountable, External

The miniature miConverter 10/100 and miConverter 10/100 Plus are rate-switching 10/100 RJ-45 copper to 100BASE-FX fiber media converters. miConverter provide cost-effective fiber connectivity from Ethernet switches to diagnostic equipment, desktop and laptop computers.

They can be powered by a computer's USB port using the optional USB Power Adaptor Cable, which reduces the module's weight and eliminates the need to tether the miConverter to an electrical outlet.

The RJ-45 port can auto-negotiate by detecting the speed and duplex-mode of the connected device. Upon connection to the UTP device, the RJ-45 port speed adjusts to either 10Mbps or 100Mbps, and the duplex-mode adjusts to either Full-Duplex or Half-Duplex. Auto-crossover enables the connection to workstations (MDI port) or hub/switches (MDI-X port) without requiring a crossover cable.
