The ComNet CNFECL1MC and CNFE1CL1MC-M are environmentally hardened modems that support Ethernet over twisted pair or coaxial cable 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 75Ω coaxial cable circuits, making these rugged units 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 CNFECL1MC-M may be deployed in most out-of-plant installations, such as those found in intelligent transportation systems and factory automation/control applications.
Features for CNFE1CL1MC Series
- 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
- Symmetric line rates of over 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. 10/100 BASE-T/TX Ethernet port with automatic MDI/MDI-X crossover
- Screw Terminals for twisted copper circuits, or BNC connector for coaxial cable
- Fully compliant with the environmental requirements (ambient operating temperature, mechanical shock, vibration, humidity with condensation, high-line/low-line voltage conditions, and voltage transient protection) of NEMA TS-1/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.
- Electric Port Supports Auto-negotiation for Full Duplex or Half Duplex Data Throughput
Applications
- Ethernet transmission over existing copper telephone-grade, serial or 75Ω coaxial cable
