Introduction

Belden® paired cable products are manufactured in a variety of gage
sizes, dimensions, insulation materials, shielding configurations,
and jacketing materials including Plenum and High-Temperature
versions to meet the technical requirements of many different types
of systems.
　

Paired cables allow balanced signal transmission, which results
in lower crosstalk through common mode rejection. Due to the
improved noise immunity of twisted pairs, they generally permit
higher data speeds than multi-conductor cables.
　

As an aid to proper cable selection, both the suggested working
voltages and the maximum temperature ratings are indicated for
each applicable paired cable selection.
　

Most of our paired cables are available from stock. Many of these
are available off the shelf from distributors. If you have a new or
unusual application or you cannot find a paired cable in this catalog
section that meets your technical requirements, contact Technical
Support at 1-800-BELDEN-1.
　

Paired Cables Packaging
Belden’s unique UnReel® cable dispenser is available for many
of the paired cable products listed in this section. The letter “U”
before the specified put-up length denotes UnReel packaging
