Cable Testing for Existing Category 5 Cable

Installed Category 5 cabling must pass tests for Attenuation, Near-End Crosstalk
(NEXT), and Far-End Crosstalk (FEXT). This cable testing information is specified in
the ANSI/TIA/EIA-TSB-67 standard. Additionally, cables must also pass test
parameters for Return Loss and Equal-Level Far-End Crosstalk (ELFEXT). These
tests are specified in the ANSI/TIA/EIA-TSB-95 Bulletin, “The Additional
Transmission Performance Guidelines for 100 Ohm 4-Pair Category 5 Cabling.”

Note that when testing your cable installation, be sure to include all patch cables
between switches and end devices.

Adjusting Existing Category 5 Cabling to Run 1000BASE-T

If your existing Category 5 installation does not meet one of the test parameters for
1000BASE-T, there are basically three measures that can be applied to try and
correct the problem:

1.

Replace any Category 5 patch cables with high-performance Category 5e or
Category 6 cables.

2.

Reduce the number of connectors used in the link.

3.

Reconnect some of the connectors in the link.

Fiber Standards

The International Telecommunication Union (ITU-T) has standardized various fiber
types for data networks. These are summarized in the following table.

Table B-3 Fiber Standards

ITU-T

Standard

Description

Application

G.651

Multimode Fiber

50/125-micron core

Short-reach connections in the

1300-nm or 850-nm band

G.652

Non-Dispersion-Shifted

FiberSingle-mode, 9/125-micron core

Longer spans and extended reach.

Optimized for operation in the

1310-nm band. but can also be used

in the 1550-nm band

G.652.C

Low Water Peak

Non-Dispersion-Shifted Fiber

Single-mode, 9/125-micron core

Longer spans and extended reach.

Optimized for wavelength-division

multiplexing (WDM) transmission

across wavelengths from 1285 to

1625 nm. The zero dispersion

wavelength is in the 1310-nm region.
