DCM’s new broadband telecom cable test system

DCM Industries, a leading worldwide producer of cable test and measurement solutions and now part of Beta LaserMike, has released its new 3S-PCX broadband telecom cable test system and new CATS-3000 shielding effectiveness test system. Utilising DCM’s solid-state-switching platform, the company introduces a new generation of test systems for telecom cables. The new Model 3S-PCX covers the complete range of applications for telecom cables, from 100 kHz to 100 MHz applications. Traditional as well as new international telecom cable standards for xDSL and other broadband applications (including ASTM, IEC, ANSI-TIA) can be quickly and automatically tested. The feature-rich 3S-PCX includes 26-pair/52-pair/104-pair test fixture options, dual impedance features, and updated test reporting. The new Model CATS-3000 from DCM provides a tri-axial test fixture and test automation software enabling the testing of all three of the standard shielding effectiveness test parameters required for data cables. Utilising the CATS-3000 test solution, combined with a suitable vector network analyser, cable producers and test laboratories can quickly and efficiently perform shielding effectiveness tests. In addition to the 3S-PCX and CATS-3000 systems, also available are the following solutions for cable production applications:

❍ ❍ The new 3S-PCX from DCM

• 3SXLD – comprehensive LAN cable testing solution for Cat 5e, Cat 6, Cat 6a, and Cat 7 cables • ES-2G – efficient compliance testing of high-performance, individually shielded, twisted-pair (Cat 7 ISTP, S/STP) cables • SCS-350B – cost-effective compliance testing of high-performance LAN cable and cable assemblies (patch cords) • RF/COAX – fully integrated test system for high performance coaxial cables • LF-2000 – twisted pair cable testing solution for analysing capacitance and resistance LCR • TCL/TCTL – LAN cable testing solution to test Transverse

Roblon introduces anti-rodent glass yarns

Furthermore, Roblon Anti-rodent Glass offers high wear resistance, thus eliminating possible issues with dust or filaments during production. Five species of rodents were used to test the efficiency of Roblon Anti-rodent Glass compared to other glass strength members. These five species of rodents are widely distributed and can be considered to represent a wide range of rodents – from the most ferocious to the most docile – that can cause damage to the commercial communication cables.

one week. The change in behaviour indicates that the rodents learn that OFC with Roblon Anti-rodent Glass tastes bad and therefore they avoid these OFCs. In fact the Indian test institute went as far as to conclude: “Thus it can be concluded that the repellent effect of the test compounds may dominate gradually and lead to a gradual elimination of the rodent attack over a period longer than the period of exposure used in the current study.” Roblon Anti-rodent Glass is a strength member and rodent protection in one and should be applied as peripheral strength member.

In response to the increasing demand for all-dielectric rodent resistant OFC, Roblon has introduced a new glass strength member named Anti-rodent Glass. Roblon Anti-rodent Glass has been developed in close cooperation with suppliers and customers and tested at a test institute in India. The Roblon Anti-rodent Glass is a glass strength member coated with a non-toxic, non-hazardous rodent aversive coating. Tests show that Roblon Anti-rodent Glass changes rodent behaviour over time and attack rate decreases after
