The ComNetTM CNFE4US Ethernet 4 port unmanaged switch Series 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 4 independent 10/100 Mbps channels in a single package. The CNFE4FX2TX2US and CNFE4FX4US require the ordering of sold-separately interchangeable SFP modules for fiber type, distance and connectors. The CNFE4FX2TX2US and CNFE4TX4US 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. All 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.
Tested and certified by an independent laboratory for full compliance with the environmental requirements (ambient operating temperature, mechanical shock, vibration, humidity with condensation, high-line/low-line voltage conditions and transient voltage protection) of NEMA TS-1/TS-2 and the Caltrans Specification for Traffic Signal Control Equipment.
Voltage transient protection on all power and signal input/output lines provides unconditional
protection from power surges and other voltage transient events.
