Comnet CNFE2CL2MC Specsheet

2 Ethernet channels over 2 twisted pair or

2 coaxial cables using VDSL2 (EoVDSL)* technology

CNFE2CL2MC

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

EXTENDERINCLUDED

› 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

› Lifetime warranty

› Made in the USA

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

Industrial Security:

› Any Ethernet-compatible equipment with a maximum

data rate of 100 Mbps

› Ethernet-compatible access control systems, intercom

systems, and IP-compatible CCTV camera surveillance
networks

› VOIP (Voice over IP) telephony networks & wireless LAN

access points

ITS/Transportation & Factory Automation/Industrial Control:

› Connecting Ethernet-based traffic signal controller units

onto an existing twisted copper pair or coaxial cable circuit

› Video Detection Systems (VDS) for analyzing traffic flow

patterns and disturbances

› Connecting Ethernet-compatible remote telemetry and

sensing devices for industrial/SCADA networks

* EoVDSL is an acronym for Ethernet over Very High Speed Digital
