Length
• The physical length of the Permanent Link/Channel is
the sum of the physical lengths of cables between
the two end points.
• The physical length of the Permanent Link/Channel may be
determined by the following three methods:
– Physically measured by the cable lengths
– Determined by the cable length marks
– Estimated by the electrical length measurement
• The electrical length is derived from the signal propagation
delay and depends on the cable construction and material
properties.
Length
• The electrical length is derived from the signal propagation
delay and depends on the cable construction and material
properties.
• When physical length is determined by the electrical length,
the physical length of the Permanent Link/Channel
calculated by the shortest electrical delay pair shall be
reported and used for making the Pass or Fail decision.
• The Pass or Fail criteria is based on the maximum length
permitted for the Channel or Permanent Link plus 10%
of nominal velocity of propagation (NVP) uncertainty.
Length
• Calibration of NVP is essential for the accuracy of length
measurements.
Almost all Signamax brand cable products are labeled with
NVP value, determined by the manufacturer for the certain
nomenclature product number.
NVP value is applied on the cable sheath surface within the
standard marking.
• Incorrectly set NVP may also significantly influence Insertion
Loss test results when testing per ISO/IEC 11801
specifications. The ISO/IEC 11801 Insertion Loss limit
formula includes dependency on the length of the cabling
segment under test.
Length
• On warranty registration of the Signamax Cabling System,
the length of the Channels and Permanent Links shall be
determined ONLY BASED ON THE PHYSICAL LENGTH
OF THE CABLE JACKET.
• Testing of the cable segment length with the field tester is
performed only to detect the installation errors and ensure
that the signal propagation path is maintained within
the permissible time limits.
Insertion Loss
• Insertion loss is a measure of signal loss in the Permanent
Link or Channel.
• Insertion Loss increases with temperature.
• The maximum insertion loss contribution permissible for
equipment and patch cords is 20% higher than for
the Horizontal cable.
• The maximum insertion loss contribution permissible for
twisted-pair equipment and patch cords is 50% higher than
for the Horizontal cable.
Insertion Loss
• The Channel insertion loss is determined as the sum of:
– IL of four (4) connectors
– IL of Work Area, equipment, and cords at 20 °C (68 °F):
• 10 m (33 ft) of 22-24-AWG cords
• 8 m (26 ft) of 26-AWG cords
– IL of 90-m (295-ft) cable segment at 20 °C (68 °F)
• The Permanent Link insertion loss is determined as
the sum of:
– IL of three (3) connectors
– IL of 90-m (295-ft) cable segment at 20 °C (68 °F)
NEXT Loss
• Pair-to-pair NEXT loss is a measure of signal coupling from
one pair to another within a twisted-pair cabling
Channel/Permanent Link and is calculated by swept/stepped
frequency or equivalent voltage measurements.
• The result of NEXT testing shall be comprised by 12 values.
• NEXT loss values greater than 60/65 dB shall revert to
a requirement of 60/65 dB.
PSNEXT Loss
• PSNEXT loss is determined with regard to the combined
crosstalk (statistical) on a receive pair from all near-end
disturbers operating simultaneously.
The PSNEXT loss is calculated as a power-sum on a
selected pair from all other pairs.
• The result of PSNEXT testing shall be comprised by 8
values.
• PSNEXT loss values over 57/62 dB should be reverted
to the requirement of 57/62 dB.
FEXT/ELFEXT/ACRF Loss
• FEXT loss is a measure of the undesirable signal coupling
from the near-end transmitter into the other pair measured
at the far-end.
Pair-to-pair ACRF is expressed in dB as the difference
between the measured FEXT loss and the disturbed pair
insertion loss:
ACRF = FEXT – IL, dB
• The result of ELFEXT/ACRF testing shall be comprised by
24 values.
• In ANSI/TIA/EIA-568-B.1 and ANSI/TIA/EIA-568-B.2, ACRF
was referred to as ELFEXT.
PSACRF Loss
• Power-sum attenuation-to-crosstalk ratio far-end takes into
account the combined crosstalk (statistical) on a receive pair
from all far-end disturbers operating simultaneously.
PSACRF is calculated as a power-sum on a selected pair
from all other pairs:
PSACRF = PSFEXT – IL, dB
• The result of PSELFEXT/PSACRF testing shall be comprised
by 8 values.
• In ANSI/TIA/EIA-568-B.1 and ANSI/TIA/EIA-568-B.2,
PSACRF was referred to as PSELFEXT.
Return Loss
• Return loss is a reflected energy measure produced by the
cabling system impedance mismatches and especially
important for applications using simultaneous bi-directional
transmission.
Return loss is the ratio of the reflected signal power to the
input power derived from dB-measured voltages.
• Owing to the terminal accuracy of the field testers,
if the return loss values are less than 3 dB, such values shall
not be used for the Pass/Fail test conclusion.
• The return loss values over 25 dB may be displayed by the
tester as “>25 dB”.
Propagation Delay
• Propagation delay is the time for the signal propagation from
one end of the Channel or Permanent Link to the other.
• For field testing all category Channels, it is sufficient
to test at 10 MHz only and Channel propagation delay
at 10 MHz shall not exceed 555 ns.
• For field testing all category Permanent Links, it is sufficient
to test at 10 MHz only and Permanent Link propagation
delay at 10 MHz shall not exceed 498 ns.
Propagation Delay Skew
• Delay skew is a measurement of the signaling delay
difference from the fastest pair (with the lowest PD value) to
the slowest (with the highest PD value).
• The maximum permissible value of the PDS shall be
maintained for the operation of applications using
the parallel signal transfer technologies over
the several pairs.
Propagation Delay Skew
• For all frequencies within the corresponding category
frequency range, the maximum propagation delay skew for
all category Channel configurations shall be less than 50 ns.
• For all frequencies within the corresponding category
frequency range, the maximum propagation delay skew for
all category Permanent Link configurations shall be less than
44 ns.
• For field testing all category Channels and Permanent Links,
it is sufficient to test at 10 MHz only.
PSANEXT Loss
• PSANEXT loss is the power-sum of the unwanted signal
coupling from multiple disturbing pairs of one or more 4-pair
Channels, Permanent Links to a disturbed pair of another 4pair Channel or Permanent Link, measured at the near-end.
• PSANEXT loss takes into account the combined alien
crosstalk (statistical) on a receive pair from all external nearend disturbers operating simultaneously.
• Calculations that result in PSANEXT loss values greater than
67 dB shall revert to a requirement of 67 dB minimum.
Average PSANEXT Loss
• Average PSANEXT loss is calculated by averaging the
individual PSANEXT loss values, in dB, for all four pairs in
the disturbed Channel or Permanent Link at each frequency
point.
• Calculations that result in Average PSANEXT loss values
greater than 67 dB shall revert to a requirement
of 67 dB minimum.
PSAACRF Loss
• AFEXT loss is the coupling of crosstalk at the far-end from
external cabling pairs into a disturbed pair of the 4-pair
cabling under test.
• PSAACRF is the calculated power-sum from all external
cabling pairs into the disturbed pair:
PSAACRF = PSAFEXT – IL, dB
• Calculations that result in PSAACRF loss values greater than
67 dB shall revert to a requirement of 67 dB minimum.
Average PSAACRF Loss
• Average PSAACRF is calculated by averaging the individual
PSAACRF values in dB for all four pairs in the disturbed
Channel or Permanent Link at each frequency point.
• Calculations that result in average PSAACRF loss values
greater than 67 dB shall revert to a requirement of 67 dB
minimum.

ONE JUMPER REFERENCE
METHOD
Step 1 (Calibration)
• Connect the light source and power meter with the reference
jumper #1.
• Measure the power level and write it down as P1.
• P1 – calibration power.
Step 2 (Calibration)
• Disconnect the reference jumper #1 from the power meter.
• Connect the jumper #2 to the power meter.
• Connect the reference jumper #1 with the jumper #2 with any
relevant connecting hardware (adapter).
Step 3 (Calibration)
• Measure the power and write it down as P1-2.
• Disconnect the jumpers, then re-connect them and measure
the power once again.
• Repeat this procedure several times (3-5).
• Any measured values shall not exceed 0.75 dB (P1-2 – P1)
and have only a slight difference between each other (<0.2
dB).
• The values above 0.75 dB indicate on one or both defective
jumpers.
Step 3 (Calibration)
• During the measurement procedure do not disconnect the
reference jumper #1 from the light source and the jumper #2
from the power meter and do not switch off power of the light
source and the power meter.
• If you did it accidentally, repeat the procedures 1 through 3.
Step 4 (Measurement)
• Disconnect the jumpers.
• Connect the reference jumper # 1 and jumper #2 to the
relevant ends of the optical fiber link to be tested.
• Measure the power and write down the result as P2.
• Loss inserted by the optical fiber link:
IL (dB) = P1 – P2
One Jumper Reference
• In procedures 2 and 3 of one reference jumper method
the quality of the test cords used for the optical fiber link
testing is verified.
• While using the certified test optical fiber cords, the power
meter and light source with the storage function of
the calibration power value (autocalibration function) some
of the previously mentioned procedures may be excluded
from the general measurement design.
TEST PARAMETERS
Test Parameters
• Testing of the optical fiber components and systems includes
measurements of several major characteristics.
• For the certification testing of the majority of the optical fiber
cabling systems, installed in the buildings and campus
environments, it is usually sufficient to get the data on
insertion loss and optical length.
• Bandwidth (multimode) and dispersion (singlemode) are
important performance parameters, however as they cannot
be adversely affected by installation practices, they should
be tested by the fiber manufacturer and do not require any
field testing.
Insertion Loss
• Link insertion loss is based on the use of the One Reference
Jumper Method specified by ANSI/TIA/EIA-526-14-A, Method
B and ANSI/TIA/EIA-526-7, Method A.1.
• The test configuration of the link insertion loss does not
include any active or passive devices other than cable,
connectors and splices (i.e., optical bypass switches,
couplers, repeaters or optical amplifiers).
Insertion Loss
15 Any optical fiber Links of the Horizontal and Backbone
cabling subsystems shall be tested for insertion loss
Insertion loss test shall be carried out by the one
reference jumper method.
Insertion Loss

Any insertion loss measurement results are
recommended for the registration with one significant
decimal digit in the fractional part
of the measured value
(for example, “–14.3 dBm”).
Horizontal Cabling
• The Horizontal optical fiber cabling subsystem link segments
require the testing at only one wavelength.
• Owing to the short cabling length (90 m (295 ft) or less),
attenuation deltas due to wavelength are insignificant.
Horizontal Cabling
16 The Horizontal optical fiber cabling subsystem links
shall be tested for insertion loss at 850 nm or 1300 nm
at least in one direction.
The insertion loss test results shall not exceed:

with a Consolidation Point
Backbone Cabling
17 The Backbone optical fiber cabling subsystem links

The insertion loss test results shall not exceed
the acceptance values derived by the link
insertion loss formulas and rules supplied in 19.
