What Is CopperPro?
| The 990DSL CopperPro Loop Tester is a portable, battery-operated handheld tester that is used in the installation testing, fault location, and digital service qualification of outside plant (OSP) paired copper cables. As a cable installation test tool, the CopperPro may be used with an external multiple pair access module in a PC-controlled mode, to perform automated, single-ended conformance testing of a newly installed cable per operating company guidelines. If more rigorous conformance testing is required, a second CopperPro with a multiple pair access module may be used at the far end of the cable, for precision terminated transmission testing. As a fault location tool, the CopperPro is used to precisely locate common physical cable faults, including shorts, grounds, crosses, opens, splits, and pair imbalances caused by poor splice joints. It may be used to expose corroded metallic faults on unused pairs, virtually undetectable by conventional meters, which will eventually cause the pair to be noisy after being cut into service. It may be used to find the root cause of transmission problems such as excessive loss and noise. It also has the ability to detect and identify loop treatment and fault-sectionalizing devices commonly installed on lines, such as range extenders (REGs), Network Interface Devices (NIDs) and Maintenance Termination Units (MTUs). As a digital service qualification tool, the CopperPro may be used to verify that the cable pair is suitable for not only voice frequency POTS services such as Caller ID and analog modem data, but also for special services such as DDS, ISDN, T1, E1, HDSL, HDSL2, and ADSL. The CopperPro uses wide-band (10kHz to 2 MHz) loss, Gaussian noise, impulse noise, and crosstalk measurements, as well as load coil detection and location capability, to qualify copper pairs for these high-speed services. |
