The JDSU T-BERD/MTS-4000 equipped with the Copper Services Moduledelivers comprehensive copper testing and addresses the distinct requirements ofvery high-speed digital subscriber line (VDSL) deployment and maintenance. TheT-BERD/MTS-4000 is a rugged, modular platform engineered with a 7-inch colordisplay, long battery life, and weather-resistant design for outstanding performanceand reliability in the field. The Copper Services Module brings the functionality tothe platform that service providers need to mitigate the significant challenge ofVDSL rollout and maintenance in various fiber (FTTx) deployments.

Traditionally, the copper plant has not been qualified to withstand the stringentneeds of VDSL service delivery. The new spectrum that VDSL uses introducesmore rigorous and stringent requirements than previously seen in the installedplant. VDSL testing has shown that the plant is susceptible to impulse noise notencountered in the current asymmetric digital subscriber line (ADSL) usagespectrum. In addition, the detection of short bridged taps, which create a muchgreater impact on VDSL signals than on ADSL signals, becomes more critical inVDSL testing. The T-BERD/MTS-4000 Copper Services Module tests to thesestandards and more to qualify and troubleshoot the copper for service.

The T-BERD/MTS-4000 is easily upgradeable with advanced options that supportthe industry’s changing technologies and the evolving needs of service installers. Itsdynamic configurability allows technicians with varying responsibilities to use it toperform a wide range of tests. Standard Ethernet and universal serial bus (USB) oroptional Wireless Fidelity (WiFi) and Bluetooth connections offer flexibility to easilydownload software and offload captured test data to improve workforce productivityand baseline network performance.



Fully compatible with the T-BERD/MTS-4000 mainframe, the dual-bay CopperServices Module can be optioned with a VDSL modem to provide support forADSL1/2/2+, VDSL1, and VDSL/VDSL2 triple-play deployments. The CopperServices Module features dual Tip (A) and Ring (B) (T&R, A&B) and Ground(Earth) interfaces. For the most accurate results, technicians can use speciallyinsulated cables to test higher-frequency services, such as VDSL2. The 4000 can alsobe used in combination with the JDSU Ultra Far End Device (UltraFED) for oneperson turn-up or trouble isolation.
