Comnet CNMC2+1SFP 2 Channel 10/100/1000 Mbps Ethernet SFP, ComFit Standard Unit

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. It can be powered by wide range of AC or DC input power supplies.

Features

• Optical port supports 100/1000 Mbps full duplex data
• Full-duplex transmission of 10/100/1000 Mbps Ethernet
  – 2 × 10/100/1000BASE-TX electrical ports
  – 1 × 1000BASE-FX or 100BASE-FX optical port when used with suitable Comnet SFPs
• 10/100/1000 BASE-TX port supports auto-negotiation and automatic MDI/MDI-X crossover for full and half-duplex operation
• Uses customer-installed Comnet SFPs for compatibility with a wide range of optical fibers, optical connector types, and optical transmission distances of up to 120 km
• Link Fault Pass-Through feature detects if either of the copper ports are down and triggers the optical port to switch states to indicate the failure to the head-end
• Designed to meet full compliance with the environmental requirements (ambient operating temperature, mechanical shock, vibration, humidity with condensation, high-line/ lowline 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 protection from power surges and other voltage transient events
• LED status indicators confirm operating status
• Plug-and-play design ensures ease of installation and no electrical or optical adjustments are ever required
• Full size units feature a contact closure output for remote side link failure detection
• Standard size is hot-swappable rack module
• Standard size is interchangeable between stand-alone or rack mount use – ComFit
• IEEE 802.3 compliant
