CopperTest - UTest 100 Overview

The CopperTest 100 has been specifically designed for testing the 'last mile' copper at the end of Fibre to the Building installations (FTTB) or from within the building. Our small practical unit provides full copper test head functionality in an ultra-low cost package. It has been designed to eliminate the huge OpEx costs associated with fault detection in building wiring and identifying customer termination problems. The CopperTest 100 can be supplied as a stand alone Test Head or as an OEM module that can be built into an existing rack or product. A fully specified command set allows the user to incorporate the module control into existing customer management systems.

A complete Test Access solution can also be provided, including all the Test Access Matrix, operating software and control equipment.
