New Bonded Cat. 6 Cable From Belden

From September, Belden’s JRJD Category 6 bonded pair cable will be replaced by a more advanced and higher performance cable.

Belden’s new unshielded twisted pair DataTwist 6x (7812E) is technically superior to JRJD while still offering Belden’s patented bonded pair design, which ensures ‘installable performance’.

Bonded Category 6 cable is used for horizontal and building-backbone installations where a high data rate transfer is required, LANs and WANs. It supports current and future Cat. 6 and Cat. 5e enhanced applications such as 10 Base-T, 100 Base-T, 1000 Base-T (Gigabit Ethernet), FDDI and ATM.

The new attributes of Belden’s DataTwist 6x include:

* the spline material is a low smoke zero halogen (LSOH) compound that also incorporates a flexible strength member that assists in hauling and helps prevent the spline from stretching;

* the diameter of the cable is slightly smaller than the JRJD;

* in addition to meeting ANSI/TIA/EIA 568-b.2 (2002), it meets ISO/IEC 11801 (2002) and EN 50173 2nd edition specifications;

* the PVC sheath material is also flame retardant;

* a very good average characteristic impedance up to 100 MHz (100 ± 5 Ohm).

Composition of the new DataTwist 6x comprises four unshielded and bonded twisted pairs with solid bare copper conductor, polyolefine insulation, LSOH spline and a flame retardant PVC jacket. The outer diameter is a nominal 6.5 mm.

Mr David Leadbetter, marketing manager of Belden Australia, said unbonded Cat. 6 cable causes many problems that often results in a non-conforming installation.

“Belden conducted an international survey of installers in 2002 to assess the cost benefits of using bonded pair cables. We found that the average number of failures per 100 drops was reduced from 14 (unbonded) to 5 (bonded),” he said.

Bonded pair technology ensures twisted pairs will not loosen during manufacture when it is being wound on and off reels or during installation when it is being handled and bent around corners. These actions can upset normal cable characteristics.

“When twisted pair cable separates there is a high probability that the electrical parameters of the cable will fail. This causes frustration for everyone, delays completion and increases costs, especially if the cable has to be replaced,” Mr Leadbetter added.

Organisations that have chosen Belden bonded pair technology as their preferred structured cable solution include TransACT, Coles Myer, NSW Police, Swinburne University, Woolworths, Latrobe University, Melbourne University and University of Technology in Sydney.
