The Tescom 990VDSL CopperPro Loop Tester with TDR and wideband spectral analysis for VDSL provides a full range of troubleshooting, fault locating, testing and qualification capabilities. The 990VDSL is a portable, battery-operated handheld tester that is used for cable installation testing, fault location, and digital service qualification of outside plant (OSP) paired copper cables. As a cable installation test tool, you can use the CopperPro with an external multiple-pair access module in a PC-controlled mode to perform automated, single-ended conformance testing of a newly installed cable according to operating company guidelines. If more rigorous conformance testing is required, you can use a second CopperPro with a multiple-pair access module at the far end of the cable to perform precision-terminated transmission testing.

As a fault location test tool, the 990DVDSL can precisely locate common physical cable faults, including shorts, grounds, crosses, opens, splits, and pair imbalances that are caused by poor splice joints. The tester can also be used to expose corroded metallic faults on unused pairs. This type of problem, which is virtually undetectable by conventional meters, can eventually cause a pair to be noisy after it is cut into service.

The 990VDSL CopperPro is also a useful tool for helping you find the root cause of transmission problems, such as excessive loss and noise. Additionally, it can detect and identify loop treatment and fault-sectionalizing devices that are commonly installed on lines, such as range extenders (REGs), Network Interface Devices (NIDs), and Maintenance Termination Units (MTUs). As a digital service qualification test tool, you can use the CopperPro to verify that a cable pair is suitable for voice frequency POTS services (such as Caller ID and analog modem data) and for special services, such as DDS, ISDN, T1, E1, HDSL, HDSL2, HDSL4 and ADSL. The DSL990 uses wideband loss, Gaussian noise, impulse noise, and crosstalk measurements, as well as load coil detection and location capability to qualify copper pairs for these highspeed services.

The DSL990 provides top performance with fewer tools to carry. Plus, its rugged construction and easy-to-use features give your technicians the vision to build, repair, install, and maintain OSP systems more efficiently with fewer repeats.
