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.

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.
