ComNet CNFE2CL2MC is an environmentally hardened modem that supports two Ethernet channels over two twisted copper pairs or two coaxial cables at data rates of up to 91 Mbps. The fastest usable data rate is automatically selected, depending upon the copper circuit transmission distance and cable quality. Utilizing the latest generation VDSL2 technology for the fastest data rate and greatest transmission distance, 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. The CNFE2CL2MC may also 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 10/100/1000 Mbps Ethernet managed switch. LED status indicators are provided for rapidly ascertaining the operating status of the modem and the link. Plug-and-play design ensures ease of installation, and no electrical or optical adjustments are ever required. Designed for long-term reliable operation in harsh industrial environments, the CNFE2CL2MC may be deployed in most out-of-plant installations, such as those found in intelligent transportation systems and factory automation/control applications. Packaged in the exclusive ComNet ComFit housing, these units may be either shelf/wall or rack-mounted. Containing two independent EoVDSL modem units within one compact package, the CNFE2CL2MC is perfect for those applications where high rack density is required, or space may be limited. It may also be DIN-rail mounted by the addition of ComNet model DINBKT1 adaptor plate.

Features

  • Utilizes latest VDSL2 technology for 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/short-reach selection
  • IEEE 802.3 compliant
  • 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.
  • Designed for installation in harsh out-of-plant/ unconditioned industrial or roadside operating environments (-40 º to +75 ºC ambient). Fully compliant with the environmental requirements of NEMA TS-2 for Traffic Signal Control Equipment
  • Screw Terminals for twisted copper circuits, or BNC connector for coaxial cable
  • Plug-and-play design ensures ease of installation and no electrical or optical adjustments are ever required.
  • Voltage transient protection on all power and signal input/output lines provides protection from power surges and other voltage transient events.
  • ComFit standard form factor is interchangeable between stand-alone or rack mount use.
  • Electric Port Supports Auto-negotiation for Full Duplex or Half Duplex Data Throughput

Applications

  • Point-to-Point or Drop-and-Repeat/Point-to-Multipoint Ethernet transmission over existing telephone-grade copper, legacy serial, or 75Ω coaxial cable circuits
