Comnet CNFE2MC2C-M Specsheet

10/100Mbps Ethernet Electrical to Optical

Media Converter with Contact Closures

CNFE2MC2C[/M]

HARDENEDINCLUDED CONVERTER

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.
