The L312 is a managed UTP to Fiber Ethernet Media Converter. It extends 10BASE-T UTP segments up to 120km over Single Mode fiber. It is designed for installation into Canoga Perkins carrier class UCS platform, and is also available as a standalone for desktop or wall mount installations.

The L312 is an IEEE 802.3 compliant device available with a variety of Multimode and Single Mode optics options to address a complete spectrum of LAN extension applications. It is NEBS level 3 tested and certified and provides an extremely reliable, yet cost effective solution suitable for the most stringent network deployments.

Through user selectable Link Loss Forwarding, and Canoga Perkins unique Link Loss Echo features, the L312 reliably facilitates the detection, isolation, and reporting of problems. A set of front panel LEDs provide the network manager visual status on the state of the device and the entire link.

The L312 supports SNMP and Telnet Management using the EdgeAccess Domain Management Module (DMM) capable of managing up to 240 modules using a single IP address. The user may monitor activities through the use of the Command Line Interface (CLI) included with the L312 or by using CanogaView?, a graphics based Network Element Manager.
