Multipair

Quabbin DataMax multipair cable for T1, E1 and xDSL circuits – 22, 24 and 26 AWG, from 2 to 12 pair, unshielded overall with individually shielded pairs. Micro-Ray is a Quabbin Wire and Cable distributor and lists 17 constructions. Please call for pricing and availability.

Why the pairs are shielded individually

On a T1 or xDSL span the enemy is crosstalk between pairs in the same sheath, not noise from outside it. These constructions therefore screen each pair on its own and leave the cable unshielded overall, which keeps near-end crosstalk down without the stiffness and the bonding work an overall screen brings. It is the reason this build is specified for carrier feeds and riser runs rather than a general-purpose data cable.

What is listed

• Gauges – 22 AWG for the longer spans, 24 AWG for most building work, and 26 AWG where the duct is tight (QBN-9760).
• Pair counts – 2, 4, 6, 8 and 12 pair.
• Jackets – PVC across most of the range, CPE on QBN-9928, and ECTFE on QBN-9738 where temperature or chemical exposure rules PVC out.
• Jacket colours – beige, green, gray and chrome gray, so a span can be colour-coded on site.

Full conductor, shield and jacket data for each construction is on its own product page, taken from the manufacturer datasheet.

Ordering

Cut and reeled to your footage, so quantity and put-up drive the price. Send the Quabbin number, or the gauge and pair count from the drawing, and we will quote it with a lead-time. If we do not have stock and you have a requirement for these parts, we will manufacture and release the material as you need it.
