Cable Tester analyzes broadband lines over copper cables.
November 17, 2008 -
Multipro Copper tester allows single operator to measure all parameters of cable from near end to far end using optional transponder, which receives control signals generated by tester and sent down cable under test. Device incorporates test functions for frequency response, return loss, and noise, and diagnostics for crosstalk, induced voltages, interference, and noise. Analysis is carried out using integral spectrum analyzer, oscilloscope, and time domain reflectometer.
Trend Communications Launches a Tester for the Installation and Maintenance of Next Generation Broadband Lines over Copper Cables
The new Trend Multipro Copper tester verifies that the twisted pair cables to the office or home have the required bandwidth of up to 30 MHz to carry the new high speed data services such as VDSL.
The portable and rugged instrument measures cable characteristics before installation to determine whether the cable would degrade service performance. The Trend Multipro Copper now enables carriers to install high speed lines up to 5 km from the exchange so opening up higher speed broadband Internet, including TV, to many users.
The Trend Multipro Copper contains a collection of test functions to test, diagnose, analyse and measure cables, it is aimed at installers and maintainers of VDSL - the next step up from ADSL. Tests include frequency response, return loss and noise. Diagnostics cover crosstalk, induced voltages, interference and noise. Analysis is carried out using the integral spectrum analyser, oscilloscope and time domain reflectometer - TDR. Measurements include capacitance and insulation.

One major advantage is that the operator can measure all the parameters of a cable from the near end to the far end using an optional Transponder located at the far end. Normally two operators would be needed for such a test. The Transponder receives control signals generated by the tester and sent down the cable under test. Transponders can also be inserted into the cable at each joint to isolate faulty cable segments. To identify intermittent faults a Transponder can be permanently or temporarily connected at any point in the cable and activated by the tester when required.
Trend's new tester addresses the expanding broadband Internet and residential Triple Play markets. The competitively priced Trend Multipro Copper will be used by installers and maintainers of broadband connections throughout the world. The tester is easy to use - a test sequencer can be programmed to make all the measurements automatically and compare results against preset limits.
Ken Foan, Sales and Marketing Director of Trend Communications commented at the launch, "VDSL is the future of the Internet allowing high-speed Internet access, television, and telephone over one line. It's new, it's exciting and Trend is there to capitalise on it." He added, "Armed with a Trend Multipro Copper and a Trend Transponder the transmission characteristics of a broadband line can be measured or monitored with ease."
The cable tester is housed in a module which clips on the hand held universal Trend Multipro test platform. Users can reconfigure the Trend Multipro - modules are available to address other test applications including Triple Play, Gigabit Ethernet, VoIP, data, video and ADSL/VDSL.
Product Manager Alan Keene is very enthusiastic about the new Trend Multipro Copper which will complement the current 2.2 MHz Trend ALT2000. He said "Trend has a long history of hand-held cable and telecommunications testers. The new tester covers to the higher frequency of 30 MHz now required for the new VDSL2 standard. The Trend Multipro test platform provided an excellent basis for the tester since all the display and control software was already fully operational. We have extended the facilities to ensure it is easy to use and simple to interpret results and carry out limit checking."
Most broadband Internet connections rely on a pair of copper wires from the local exchange or street cabinet to the office or home. These wires were only intended to carry very low frequency voice traffic, not high speed data. To overcome the limitations of the wires broadband connections use a technology called DSL (Digital Subscriber Line). DSL employs Discrete Multi-tone Modulation (DMT) which uses many sub-carriers over a wide frequency range each carrying a part of the overall digital traffic. To carry DSL the copper wires must pass these high frequency tones without interference or degradation.
The Trend Multipro Copper measures key parameters of the wires including the electrical properties, noise and crosstalk, frequency response, interference and attenuation (loss). If there are imperfections in the wires Internet failures and intermittent operation occurs, so it is vital to be able to make the measurements to characterise the performance of the wires. Wires with imperfections must be located and not used for broadband if the subscriber is to avoid reduced bit rate or failures.
