The ComNet CNFE2EOC is a modem that supports two Ethernet channels over either two twisted pair or two coaxial cables using VDSL2 technology, at data rates of up to 90 Mbps. Ethernet data may be transmitted over a telephone-grade twisted copper pair, legacy serial cabling, or standard 75 ohm coaxial cable circuits, making this unit ideal for those applications where it is desired to utilize an existing installed base of copper wiring for Ethernet transmission. These modems are the perfect solution for upgrading a legacy twisted copper or coaxial cable plant for use with Ethernet, when compared to the significant costs of installing new network cabling. The fastest usable data rate is automatically selected, depending upon the transmission distance and cable quality. The unique ComFit package configuration provides either stand-alone or card cage mounting. LED status indicators are provided for rapidly ascertaining the operating status of the modem and the link.
Features for CNFE2EOC
- Utilizes latest VDSL2 technology for fastest data rate transmission and greatest transmission distance
- Supports transmission distances of up to 10,000 ft (3 km) over twisted copper, or up to 1500 ft (457 m) over coaxial cable
- 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
- Full auto-negotiation and automatic MDI/MDI-X crossover
- Two-Channel Design: Contains two independent EoVDSL modem units in one compact package.
- Plug-and-play design ensures ease of installation and no electrical or optical adjustments are ever required.
- Screw Terminals for twisted copper circuits, or BNC connector for coaxial cable
- Ideal for multiplechannel Ethernet-over-VDSL applications where rack or shelf/ wall space may be limited
- Symmetric data transmission rates of up to 91 Mbps
- 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.
- 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
- Industrial Security: Any Ethernet-compatible equipment with a maximum data rate of 100 Mbps
- Industrial Security: Ethernet-compatible access control systems, intercom systems, and IP-compatible CCTV camera surveillance networks
- Industrial Security: VOIP (Voice over IP) telephony networks
- ITS/Transportation: Connecting Ethernet-based traffic signal controller units onto an existing twisted copper pair or coaxial cable circuit
- ITS/Transportation: Video Detection Systems (VDS) for analyzing traffic flow patterns and disturbances
