The ComNet CNFE2MC2C[/M] Ethernet media converter is designed to transmit and receive 10/100 Mbps data and two bi-directional contact closures over multimode or single mode optical fiber using sold-separately SFP* modules to select distance and connector type. The electrical interface will Auto-Negotiate to a 10 Mbps, or 100 Mbps Ethernet rate without any adjustments. The optical interface operates at a 100 Mbps Ethernet rate. These media converters are environmentally hardened to operate in extreme temperatures. The CNFE2MC2C/M small package size is ideal for locations where space is at a premium. Packaged in the exclusive ComNet ComFit housing, the full size CNFE2MC2C may be rack-mounted, or may be DIN-rail mounted by the addition of ComNet model DINBKT1 adaptor plate.
