Comnet CNFE2CL2MC 2 Ethernet Channels over 2 Twisted Pair or 2 Coax

The ComNet™ CNFE2CL2MC is an environmentally hardened modem that supports two Ethernet channels over two twisted copper pairs or two coaxial cables. Any standard telephone-grade twisted copper pair, legacy serial cabling, or standard 75 ohm coaxial cable may be used, making this unit ideal for those applications where it is desired to utilize an existing installed base of copper wiring for Ethernet transmission, when compared to the significant costs of installing new network cabling. LED status indicators are provided for rapidly ascertaining the operating status of the modem and the link. Packaged in the exclusive ComNet ComFit housing, these units may also be DIN-rail mounted by the addition of ComNet model DINBKT1 adaptor plate.

Features

• Utilizes the latest VDSL2 technology for the fastest data rate transmission and greatest transmission distance.
• Two-Channel Design: Contains two independent EoVDSL modem units in one compact package. Ideal for multiplechannel Ethernet-over-VDSL applications where rack or shelf/wall space may be limited
• Supports transmission distances of up to 10,000 ft. (3 km) over twisted copper, or up to 1500 ft. (457 m) over coaxial cable
• Symmetric data transmission rates of up to 91 Mbps
• Automatically sets fastest possible data rate vs. cable quality and transmission distance
• User-configurable master/remote, forward error correction, asymmetrical/symmetrical data, and long-reach/shortreach selection
• IEEE 802.3 Compliant. 10/100 BASE-TX Ethernet port with automatic MDI/MDI-X crossover
• May be used as an uplink modem, easily enabling the configuration of a drop-and-repeat/point-to-multipoint EoVDSL communications network by the addition of any managed 10/100/1000 Mbps managed Ethernet switch.
• Plug-and-play design ensures ease of installation, and no electrical or optical adjustments are ever required.
• Designed for installation in harsh out-of-plant/unconditioned industrial or roadside operating environments (-40º to +75ºC ambient). Fully compliant with the environmental requirements of NEMA TS-2 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
• Screw Terminals for twisted pair copper circuits, or BNC connectors for coaxial cable
• Unique ComFit Package: May be utilized as a stand-alone package, or may be mounted within the ComNet C1 or C2 Card Cage, and is fully hot-swappable
