INSTALLATION AND OPERATION MANUAL
CNMC[2,4]SFP[POE][/M] Series
10/100/1000MBPS ETHERNET MEDIA CONVERTERS
WITH 100FX AND 1000FX SUPPORT
This manual serves the following
ComNet Model Numbers:
CNMCSFP/M
CNMCSFPPOE/M
CNMCSFP
CNMC2SFP
CNMC4SFP
The ComNet CNMCSFP electrical-to-optical Ethernet media converters accept a
10/100 or 1000 Mbps electrical input and converts this to a 100 or 1000 Mbps
optical output (selected by a dip switch) and the 100/1000 Mbps optical input
back to the 10/100/1000 Mbps electrical output. “Auto-Negotiating” is supported
on the copper interface side. These devices use either one or two optical fibers,
depending upon the selection of sold-separately SFP† optical module. A PoE model,
the CNMCSFPPOE/M meets the IEE802.3at standard and provides 30 watts of PoE+
power. The series consists of a small-size single channel model, CNMCSFP/M; a
ComFit standard size, single-channel model, CNMCSFP; a dual channel model,
CNMC2SFP; and a quad channel model, the CNMC4SFP.
