Patton CL1212E/EUI-2PK Ruggedized Ethernet Extender Kit

SKU: 963 Category:



Perfect for bandwidth-intensive applications the CopperLink™ 1214E delivers off-the-chart symmetrical line rates greater than 168 Mbps. Best of all—like all CopperLink™ products—the CL1214E leverages existing copper infrastructure to deliver high speed Ethernet connectivity over single twisted-pair or Cat 5e/6/7 cable.

Four user-selectable configuration profiles—combined with Patton’s auto-rate adaptation feature—ensure maximum achievable symmetrical or asymmetrical rates for the installed noise environment, wire gauge/type and length. 

Symmetrical line-rate settings are ideal for such applications as remote LAN extension, video teleconferencing, and data backhaul. 

Asymmetrical configurations are well-suited for applications requiring higher downstream speeds and/or longer distances between Ethernet devices. Typical asymmetrical scenarios include medical imaging, livestock monitoring, underwater video, internet gaming, and transporting high-resolution IP video from security cameras.

Realize fiber-like speed and distance without the expense of fiber with Patton’s Ultra-High-Speed CopperLink™ Ethernet Extenders. 


  • Ethernet Extension— Extend 10/100Base-TX Ethernet well beyond its 328-foot (100-meter) limitation over a single unshielded twisted pair (UTP) or Cat 5e/6/7 cable.
  • Ruggedized—Operating temperature of -40 to 85°C and optional conformal coating to protect against condensing humidity.
  • Plug and Play—Set these units up straight out of the box. No configuration is required. Auto-sensing 10/100 Ethernet ports support full or half duplex operation.
  • Transparent LAN Bridging—Bypass network configuration requirements by transparently passing all higher layer protocols—including 802.1Q VLAN frames (tagged and untagged). Data-transmission mechanism is fully transparent to such IP video compression schemes as MPEG-4, H.264 and MJPEG.
  • Flexible Installation—Wall-mount ready and an optional DIN rail mounting kit is available.
  • Multiple Line Rates Supported—Switch-selectable rate mode options optimize rate and reach for the noise environment, wire gauge/type and length.
  • Made in the USA — This Patton equipment is designed by Patton engineers and built in our Gaithersburg, Maryland facility. Patton's American-made manufacturing process delivers high-quality networking solutions with reliability you can trust.

Typical Application A built-in 4-port Ethernet switch makes the CopperLink 1214E ideal for delivering multiple IP information streams over a single cable. For example, at a guardhouse or security kiosk, you could aggregate IP data from a laptop, a motion sensor, and two high resolution IP video cameras for simultaneous transmission over a single Ethernet connection. 

Combining data flows from up to four network-enabled devices onto a single twisted pair, the Model 1214E can deliver IP traffic up to 1.8 miles (3 km) away—well beyond the standard 328-foot (100-meter) Ethernet distance limitation. 

With achievable line rates up to 168 Mbps, the CopperLink 1214E eliminates the bandwidth constraints commonly experienced with other copper-based transmission technologies. The Model 1214E is engineered to re-use existing infrastructure previously employed in legacy applications including alarm circuits, E1/T1 circuits, RS-232, RS-422, RS-485, CCTV and CATV. Many newer cabling standards are also supported, including Cat 5e, Cat 6, and Cat 7.
