CAT5ESHIELDED TWISTED-PAIR (STP)PATCH CABLES

CAT5ESHIELDED TWISTED-PAIR (STP)PATCH CABLES
CAT5E SHIELDED TWISTED-PAIR (STP) PATCH CABLES
Protect CAT5e lines from noise.
Key Features
The cost-effective
alternative to fiber
optic cabling in highnoise environments.
Foil shielding protects
signals from EMI/RFI.
Reliable performance
in extreme climate
conditions.
Support 100-MHz or
155-Mbps high-speed
communications.
f you have a high-noise environment and running fiber optic
cable is not cost-effective, the
CAT5e Shielded Twisted-Pair
(STP) Patch Cables are your
practical alternative for runs
up to 150 feet and beyond.
What is noise? It is the
common term for electromagnetic
interference (EMI) or radiofrequency interference (RFI).
It’s generated by motors, fluorescent lights, air conditioners,
and office appliances.
EMI and RFI play havoc with
ordinary, unshielded copper
I
cables. But the BLACK BOX
CAT5e STP Patch Cables are
built for harsh environments. In
fact, they perform reliably in
temperatures as hot as 176°F
(80°C) or as cold as -4°F (-20°C).
These cables are built with
protective foil shielding and
support 100-MHz or 155-Mbps
high-speed communications.
The patch cables are
terminated with the T568B wiring
pattern and have slide-back,
snagless, molded gray boots.
They are ideal for applications
with TIA/EIA 568-A Category 5e
®
and ISO/IEC 11801 standards.
Choose from two versions,
either with stranded conductors
and a PVC jacket (EVNSL72GY) or
with solid conductors and a jacket
safe for plenum installation
(EVNSL73GY).
The EVNSL72GY cables are
available in lengths from 3 feet
(0.9 m) to 20 feet (6 m), and custom
lengths are also available. The
EVNSL73GY cables are available
in lengths from 25 feet (7.6 m) to
150 feet (45.7 m).
Snagless boots.
Choose from stranded
or solid conductors.
PVC and plenum-safe
jacketing available.

• It’s 6 p.m. and you need help,
but your vendor’s tech
support line is closed.
According to a survey by Data

Specifications
Technically Speaking
hielded vs. unshielded cable.
The environment determines
whether cable should be shielded or unshielded. Quiet office
environments, busy retail establishments, and industrial workshops all require different levels
of shielding.
Shielding is the sheath
surrounding and protecting the
wires of the cable from electromagnetic leakage and interference (EMI). This activity is
commonly referred to as noise.
Sources of EMI in the workplace
include elevator motors, fluorescent lights, generators, air conditioners, and photocopiers.
To protect your data from
high EMI, choose a shielded
cable. Foil is the most basic cable
shield, but a copper-braid shield
provides more protection.
Use a foil-shielded cable in
busy office or retail
environments. For industrial
environments, you might want to
choose a copper-braid shield. For
quiet office environments,
choose unshielded cable.
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 short of their expectations—
and certainly isn’t worth what
they paid.
At Black Box, we guarantee
the best value and the best
tranded vs. solid conductor.
Stranded cable is for use in
shorter runs between network
interface cards (NICs) and
wallplates, or between concentrators and patch panels, hubs,
and other rackmounted equipment. Stranded-conductor cable
is much more flexible than solidcore cable. However, attenuation
is higher in stranded-conductor
cable, so the total length of
stranded cable in your system
should be kept to a minimum to
reduce signal degradation.
Solid cable is for use in runs
between two wiring closets or
from the wiring closet to a
wallplate. Solid-conductor cable
shouldn’t be bent, flexed, or
twisted repeatedly. It’s designed
for both backbone and horizontal
cable runs. Its attenuation is
lower than that of strandedconductor cable.
