T1 FIBER OPTIC LINE EXTENDER/SIMULATOR

2. Introduction

2.1 Description

The T1 Fiber Optic Line Extender/Simulator lets you combine fiber optic technology with standard interfaces at 1.544 Mbps. The advantages are increased transmission distances and immunity to electrical interference. Connections between buildings become possible since no lightning currents can arise.

2.2 Features

•Extend or interconnect T1 lines, PBXs, or T1 muxes across distances up to 3 miles (4.8 km) via a pair of these devices.

•For line simulation, the device is transparent to equipment, framing, and encoding—PBXs and multiplexors act like they’re directly connected to a T1 circuit.

•EMI/RFI and lightning-hazard immunity is provided by the fiber link.
