OVERVIEW

Simplify your cabling layout and reduce the amount

of work required during workstation reconfiguration with BLACK BOX® CAT5e and CAT5 25-Pair Bulk Cables.

Zone cabling vs. traditional home run cabling.

Installing network cabling in a “home run” style configuration typically involves running an individual horizontal cable to each workstation. This configuration, however, can be a problem when it’s time to perform moves, adds, and changes (MACs). An entire length of cable may have to be rerouted, a process that’s often both time- consuming and expensive.

Our 25-pair cables are specially designed for use for zone cabling. In a zone configuration, patch cables from individual workstations are fed into a multiuser telecommunications outlet or a consolidation point. From this point, a single horizontal CAT5e or CAT5 25-Pair Cable carries voice or data the rest of the way. Not only do you need fewer cable pulls, but there’s also less cable to mess with during MACs.

In addition to zone cabling applications, you can use these cables for copper backbone and interconnect applications.

Verified performance!

Many high-pair-count designs offer cabling plant convenience but frequently lack the speed and bandwidth performance of their 4-pair cousins—not so with our CAT5e and CAT5 25-Pair Bulk Cables. With these cables, you get independently verified EIA/TIA performance to handle the increasing demands of today’s ever-faster applications. Plus, they offer a small diameter and flexible construction.

Why Buy From Black Box? Exceptional Value. Exceptional Tech Support. Period.

Recognize any of these situations?

•You wait more than 30 minutes to get through to a vendor’s tech support.

•The so-called “tech” can’t help you or gives you the wrong answer.

•You don’t have a purchase order number and the tech refuses to help you.

•It’s 9 p. m. and you need help, but your vendor’s tech support line is closed.

According to a survey by Data Communications magazine, 90% of network managers surveyed say that getting the technical support they need is extremely important when choosing a vendor. But even though network managers pay anywhere from 10 to 20% of their overall purchase price for a basic service and support contract, the technical support and service they receive falls far short of their expectations—and certainly isn’t worth what they paid.

At Black Box, we guarantee the best value and the

best support. You can even consult our Technical Support Experts before you buy if you need help selecting just the right component for your application.

Don’t waste time and money—call Black Box today.
