4000-TDR

COMMUNICATIONS TEST & MEASUREMENT SOLUTIONS T-BERD®/MTS-4000 Multiple Services Test Platform Copper Services Module Key Features • Complete copper testing from POTS through full-spectrum VDSL/VDSL2 up to 30 MHz • Time domain reflectometer (TDR) with time-varying gain (TVG) • Spectral analysis to 30 MHz with one-button zoom to VDSL bands and causes of interference • JDSU scripting and automated test features that simplify testing • Wideband copper functionality available in combination with VDSL/VDSL2 test modules • Large, color graphical user interface (GUI) with optional touch screen Applications • Qualifies and troubleshoots twisted pair copper deployments • Interoperates with the JDSU UltraFed for single-ended closeout testing • Conducts scripted closeout testing with user-definable Pass/Fail criteria The JDSU T-BERD/MTS-4000 equipped with the Copper Services Module delivers comprehensive copper testing and addresses the distinct requirements of very high-speed digital subscriber line (VDSL) deployment and maintenance. The T-BERD/MTS-4000 is a rugged, modular platform engineered with a 7-inch color display, long battery life, and weather-resistant design for outstanding performance and reliability in the field. The Copper Services Module brings the functionality to the platform that service providers need to mitigate the significant challenge of VDSL rollout and maintenance in various fiber (FTTx) deployments. Traditionally, the copper plant has not been qualified to withstand the stringent needs of VDSL service delivery. The new spectrum that VDSL uses introduces more rigorous and stringent requirements than previously seen in the installed plant. VDSL testing has shown that the plant is susceptible to impulse noise not encountered in the current asymmetric digital subscriber line (ADSL) usage spectrum. In addition, the detection of short bridged taps, which create a much greater impact on VDSL signals than on ADSL signals, becomes more critical in VDSL testing. The T-BERD/MTS-4000 Copper Services Module tests to these standards and more to qualify and troubleshoot the copper for service. The T-BERD/MTS-4000 is easily upgradeable with advanced options that support the industry’s changing technologies and the evolving needs of service installers. Its dynamic configurability allows technicians with varying responsibilities to use it to perform a wide range of tests. Standard Ethernet and universal serial bus (USB) or optional Wireless Fidelity (WiFi) and Bluetooth connections offer flexibility to easily download software and offload captured test data to improve workforce productivity and baseline network performance.

The Copper Services Module features dual Tip (A) and Ring (B) (T&R, A&B) and Ground (Earth) interfaces. For the most accurate results, technicians can use specially insulated cables to test higher-frequency services, such as VDSL2. RF Interference Impulse Noise Missing POTS Splitter CPE Interoperability Unterminated In-House Wiring Bridged Taps Internet and Triple-Play Services MDF Connection Issues Unbalanced Loop Crosstalk Bad Contacts Corroded Contacts Figure 1: Standard copper qualification may show acceptable results for typical problem areas such as attenuation and noise, but many issues impact copper quality in today’s demanding next-generation service environment, particularly unterminated in-house wiring with bridged taps that lead to unexpected effects when using new frequencies up to 30 MHz. The T-BERD/MTS-4000 large, color GUI makes reading even the most complex copper test results easy. T-BERD/MTS-4000 COPPER SERVICES MODULE 3 Overview of Copper Tests Today’s copper network requires rigorous testing.
