25 pair telephone cable (Cat3 PVC/CMR) is made for riser telephone cabling applications and constructed of 50 24 gauge solid bare copper conductors with a PVC jacket.

This made in the USA cable will qualify for all product-origin specific United States Federal Government sales requirements.

The color coding is very dark and easily distinguished to make for easy punchdown, even in low light conditions. We provide Tappan Wire and Comtran Cable due to the build quality, color coding, and compact packaging (if you order a full 1000ft spool, it will come on a 16" round x 11" wide spool, which is UPS shippable).

Through our many manufacturer contacts we have access to other types of 25 pair telephone cable that are not listed on this website. There are too many part numbers to list, but we can get you almost any type of indoor or outdoor 25 pair telephone cable as well as 25 pair data cable, from direct burial gel-filled, direct burial non gel-filled, aerial cable with and without support wire, PE89, PE22, PE38, armored cables, various conductor sizes from 19 gauge to 24 gauge, as well as Cat 5 25 pair in various constructions. Most all of this can be cut to length to suit your needs. For more information and pricing on any of these email us at
