Long Range Ethernet Extenders
CopperLink CL1314MDE Ruggedized Multi-Drop Ethernet Extender & Repeater | up to 6 miles (10 km) over copper

Use the CopperLink 1314MDE Multi-Drop Ethernet Extender to interconnect and daisy chain multiple remote networks and network enabled devices up to 6 miles (10 km) or more apart using single-twisted-pair cabling.

The CL1314MDE Multi-Drop Ethernet Extender used in conjunction with the CL1314R makes Ethernet extension a breeze. The MDE series of Ethernet Extenders allows users to replace their legacy serial coms with cost-effective Ethernet (IP) that is easy and inexpensive to set up. Featuring plug-and-play installation, the CL1314 MDE leverages existing copper twisted-pair infrastructure to interconnect Ethernet devices and networks at moderate speeds over long distances. The MDE Extender not only allows multi-drop functionality but also serves a repeater function doubling your maximum distance at every hop.

Operating over standard 0.5 mm (24 AWG) voice-grade wiring, the CL1314MDE delivers speeds up to 15.3 Mbps and extends Ethernet connections across distances up to 10 km (6.2 miles) per hop. Whether you need connect to a remote offices, kiosks, guard stations, train stations, digital sensors or IP cameras—Patton Ethernet Extenders offer the industry’s optimum combination of speed and distance. Patton’s CopperLink Ethernet Extenders ensure hassle-free set-up and operation, while achieving the highest possible line rate for the required distance and electro-magnetic environment. Users can “hard-set” the desired line rate via DIP switch, GUI or console Telnet.

Operating at layer 2 of the OSI model (data link layer), the CL1314MDE transparently passes all higher-layer protocols—including VLAN tagging, multicast addressing, VPN pass-through for IPsec, and all IP-video compression schemes. All common industrial protocols are also transparently supported, including MODBUS/TCP and PROFINET IO.


Typical Applications

Model CL1314MDE ruggedized multi-drop Ethernet extenders are ideal for delivering drop add Ethernet links to multiple remote locations that are beyond the 328-foot (100-meter) distance limit of Ethernet. The 15.3 Mbps throughput eliminates bandwidth concerns previously experienced with other legacy copper wired transmission technologies.

The CL1314MDE includes several user configurable line rates so that a user will get a consistent link, even in noisiest environments. Using existing voice-grade copper pairs or legacy serial circuits eliminates the expense and hassle of installing low capacitance or fiber cable.

When planning for mutiple drops, keep in mind that latency (the total delay that occurs when sending data from source to destination) should be less than 150 ms and should not exceed 400 ms, regardless of the type of application. See Latency for more information.
