Ethernet Extension Application
Used in pairs, the Model 2158 establishes a high speed 12.5 Mbps communications link inter-connecting two geographically separated LANs. Operation is simple: packets destined for the remote LAN are sent transparently, at full line rate, to the peered LAN.

Patton’s CopperLink Ethernet Extenders are a clearly superior and cost-effective alternative to expensive fiber and media converters, or LAN-grade cable and repeaters.
