2 CHANNEL 10/100/1000 MBPS ETHERNET
ELECTRICAL TO OPTICAL MEDIA CONVERTER
The ComNet Ethernet CNMC2+1SFP electrical-to-optical Ethernet media converters
accept two 10/100 or 1000 Mbps electrical inputs and converts this to a single 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. The
ComNet exclusive Demux feature allows for port isolation, replicating two media
converters over one fiber. The ComNet exclusive Mux feature prevents network video
flooding of multicast traffic with DIP switch selection of the fiber port as a dedicated
uplink path. The CNMC2+1SFP series can be powered by wide range of AC or DC input
power supplies.
LED indicators confirm operational status. All models are environmentally hardened
with no electrical or optical adjustments (Plug and Play). DIP Switches on the outside of
each unit allow for fine-tuning of features. See
Figures 1 – 12
for complete operation
details. See
