TASK ORDER 03: LOBBY IMPROVEMENTS – PKG 4 - CURBSIDE CHECK-IN
RONALD REAGAN WASHINGTON NATIONAL AIRPORT
PROJECT DT1203
E. 4-Pair UTP Cable Testing:
11) Contractor shall calculate PTA for each circuit and enter predicted value and
measured value on test form.
12) All test failures must be documented in the "miscellaneous notes" section of
the test form prior to correcting the failure.
13) Failing connectors shall be replaced and fully retested until they pass.
14) Negative losses (i.e. gainers) and 0dB test results are unacceptable and must
be retested by the Contractor at no additional expense to the Owner.
1. Test the 4-pair UTP horizontal cables after both ends of a UTP cable have been
connectorized and mounted into outlets, panels, or frames, thereby including losses of
the UTP cable, connectors, frames, etc.
2. Test all 4-pair UTP horizontal cables using a Level III Field Tester. Prior to commencing
the testing submit to the COTR for review, information on the field tester that shall be
used for testing, including calibration reports.
3. Perform the permanent link test on all 4-pair UTP horizontal cables.
4. Field test measurements shall be made in accordance with annex I of ANSI/TIA/EIA-
568-B.2 Standard and shall be conducted from 1 MHz to 250 MHz. For extended
Category 6 cables that exceed the 250 MHz bandwidth, test to the highest reference
frequency per the manufacturer’s recommendations.
5. Field test the following transmission performance parameters:
6. Wire map.
a. Length.
b. Attenuation.
c. Near End Crosstalk (NEXT).
d. Power Sum Near End Crosstalk (PSNEXT).
e. Equal Level Far-End Crosstalk (ELFEXT).
f. Power Sum Equal Level Far-End Crosstalk (PSELFEXT).
g. Return loss.
h. Propagation Delay.
i. Delay skew.
j. At a minimum attenuation, NEXT, PSNEXT, ELFEXT and PSELFEXT
performance parameters shall be sweep/step tested from 1 MHz to 250 MHz per
compliance with ANSI/TIA/EIA-568-B. For extended Category 6 cables that
exceed the 250 MHz bandwidth, sweep/step from 1 MHz to the highest reference
frequency per the manufacturer’s recommendations.
k. Test the NEXT, PSNEXT, ELFEXT and PSELFEXT performance parameters
from both ends of the cable.
l. Each report shall include all completed cable test forms bound in order by room
number. Record the test pass or fail on the appropriate UTP cable test form. All
test failures must be documented in the "miscellaneous notes" section of the test
form prior to correcting the failure.
m. All four-pair UTP copper cables must have the following data recorded and
submitted:
1) The cable tester used during testing.
2) Cable ID/Pair #.
