EXFO Electro-Optical Engineering Inc. introduces a copper test module for the AXS-200 SharpTESTER platform, which tests the full 30MHz VDSL2 spectrum over copper access networks. The AXS-200/610 30-MHz copper test set provides fault location as well as service pre-qualification to support ADSL2+ and VDSL2 triple-play deployments.

This latest test module is housed inside the multiservice and multimedium AXS-200 SharpTESTER modular test platform, which is a handheld WinCE-based advanced test set that can be configured for copper/DSL/triple-play, Ethernet or optical testing applications in access networks. The AXS-200 platform, when used in conjunction with the AXS-200/610 copper test module, identifies, locates and repairs copper loop plant problems that affect triple-play service quality.

The AXS-200/610 consolidates voiceband and fault location measurements together with the required wideband measurements (up to 30MHz) that are required to qualify copper loops for bandwidth-intensive triple-play services being deployed over various xDSL technologies. The AXS-200/610 is said to provide a comprehensive range of copper measurements, which allow field technicians to test copper loops for any possible application including traditional circuit-switched voice services, SHDSL, ADSL, ADSL2, ADSL2+, VDSL and VDSL2.

In order to allow network service providers (NSPs) to efficiently troubleshoot and qualify the triple-play access networks, the AXS-200/610 incorporates automated routines with simple Pass/Fail analysis for all test modes. In addition, the unique "Loop Mapper" feature automatically plots a graphical depiction of the copper loop, which visually shows the loop length, eliminating the need to interpret complex TDR traces.

EXFO has also introduced the AXS-200/625 30-MHz copper and ADSL2+ triple-play test set, another test module available for the AXS-200 SharpTESTER platform, which consolidates all the capabilities of the AXS-200/610 with the capabilities of the recently launched AXS-200/620 ADSL2+ triple-play test set to deliver a compact, all-in-one single module test solution for copper, xDSL and triple-play service testing.

By having a fully integrated test solution, there is no need to swap modules as technicians migrate from installation, provisioning and troubleshooting applications, said EXPO. In addition, the AXS-200/625 has a powerful multi-layer analysis measurement that will graphically analyze network errors and determine whether they are occurring at the physical layer, DSL layer or IP layer.
