Comnet CNFE8TX8US Unmanaged Switch, 8 Port, 100Mbps, 8 Copper

The ComNet™ CNFE8US Series Ethernet 8 port unmanaged switch is designed to transmit and receive 10/100 Mbps data over optical fiber through user selectable SFP options or 10/100 Mbps data over CAT5E/6 electrical cable. This unit integrates eight independent 10/100 Mbps channels in a single package. The CNFE8FX4TX4US and CNFE8FX8US require the ordering of sold-separately interchangeable SFP modules for fiber type, distance and connectors. All electrical interfaces will Auto-Negotiate to 10 Mbps, or 100 Mbps Ethernet rate without any adjustments. The optical interfaces operate at a 100 Mbps Ethernet rate. The CNFE8US Series models are environmentally hardened to operate in demanding environments. LED indicators are provided for confirming equipment operating status. These units are interchangeable between stand-alone or card mount configurations.
