Overview
LAN extension doesn’t have to be expensive or difficult. The 2157 LAN Extenders are easy to use and take advantage of the existing copper twisted-pair infrastructure to connect LANs at rates up to 4.6 Mbps.

Whether it’s connecting corporate LANs or remote offices, the 2157 is the simple solution for ensuring the best combination of speed and distance in the industry. Many LAN extenders are set for a single rate, or require difficult configurations in order to connect LANs at different distances. With it’s auto-rate adaptation feature, the Model 2157 ensures that users get the highest speed possible for the distances they are trying to reach. To make it even simpler to use, the Model 2157 comes with a built in MDI-X switch to allow easy connection to LANs or PCs with no need for worrying about whether you have a cross-over cable or not. Setup is as consists of connecting the Ethernet port, connecting the copper twisted pair, and powering up the units! Patton’s Model 2157 is the perfect fit for cost-effective, simple, and efficient LAN extension!
