Belden’s 7811A is a quality plenum rated product produced to the Category 5 specifications set by TIA/EIA 568-A. Additionally, 7811A is covered by Belden’s standard Data Twist® product warranty of 15 years and is approved for use with the MatchMaker Warranty(SM) program.
Belden’s new TIA/EIA 568-A compliant category 5 plenum cable has been introduced into the market place to be competitive in price with other inexpensive Cat 5 plenum cables. All aspects of this cable have been engineered to remove cost while maintaining a quality Category 5 compliant cable. The product’s Flamarrest® jacket is only available in natural and color blue. Also, there are only two put-ups available per color, both 1000' exact in length. At the pair level, the conductors are optimized to meet specified attenuation levels and twinned to comply with required crosstalk performance levels. At this time, all four pairs utilize 100% FEP Dupont Teflon®. Also, the pairs may or may not have the added identification stripes. These stripes are not required per the standard “for cables with tightly twisted pairs… the mate conductor may serve as the marking conductor for the white pair.” For further detailed information, technical data sheets are now available.
The recent introduction of TIA/EIA’s draft proposal 10a for enhanced Category 5, “Cat 5e,” has changed the way Belden’s 1585A is received in the market place. This cable has always been premium Category 5 cable exceeding the requirements set forth by the TIA/EIA 568-Category 5 standard. With the introduction of the proposed “enhanced” specifications, 1585A meets or exceeds this and can now be differentiated from the lower performing cables being sold on price. The new specification requires improved NEXT, PSNEXT, improved ACR, PSACR, improved ELFEXT, PSELFEXT, and improved return loss.
