orange in color, shall be pulled with 10 feet of slack in each pull box or handhole. All fiber
cables shall be marked with a metallic or preapproved identifier in the handhole adjacent
to the traffic signal cabinet or hub cabinet and on the cable in the hub cabinet at point of
termination. The identifier, both in the cabinet and in the handhole, shall indicate the
direction the cable is going, cable contents (SM), and the abbreviated location for the
other end destination.
6.7 Minimum Bend Radius
For static storage, the cable shall not be bent at any location to less than ten times the outside
diameter of the cable or as recommended by the manufacturer. During installation, the cable
shall not be bent at any location to less than twenty times the outside diameter of the cable or as
recommended by the manufacturer.
6.8 After the Fiber Optic Cable Installation
6.8.1 Each section of the cable shall be tested for continuity and attenuation as a minimum. If
the attenuation is found not to be within the acceptable nominal values, the Contractor
shall use an optical time domain reflectometer(OTDR)to locate points of localized loss
caused by bends or kinks. If this is not successful, the Contractor shall replace the
damaged section of cable with no additional payment. Splices will not be allowed to
repair the damaged section. After all fiber is installed, all fibers, whether terminated or
non-terminated, shall be tested with an OTDR. All fibers terminated shall be tested with a
power meter. Each OTDR trace, for documented test result submittal shall be displayed
individually and not be combined with other fiber traces as overlays. Single mode fiber

entering or leaving a splice tray(See Testing). For measured values recorded in excess
of the above(0.10 for SM) listed values, refer to the fiber parameters specification as
hereinbefore defined. The Engineer reserves the right to spot test fiber terminations,
splices, or re-testing of all fibers in a section to insure proper quality assurance both
during and after installation and testing. Deviations from Engineer testing and report
documentation shall be reviewed and the Contractor shall be able to retest any or all
challenged measurements to verify a valid test. Inconsistent test results, in the sole
opinion of the Engineer, shall cause the Contractor to retest the entire fiber installation.

6.17 Testing
6.17.1 General
The Contractor shall provide all personnel, equipment, instrumentation, and supplies
necessary to perform all testing and is considered incidental to the Project. All testing
shall be performed in the accepted manner and in accordance with the testing equipment
manufacturer's recommendations. All data shall be recorded and submitted to the
Engineer as hereinbefore specified. The Contractor shall provide one copy of operating
software to read and view all OTDR traces.
6.17.2 Attenuation
The end-to-end attenuation shall be measured for each fiber for each link after installation
and termination.A patch cord jumper cable shall be connected to both the light source
and the receive cable to the power meter by the use of a connector(barrel). The two
reference cables shall then be connected via a termination coupler and power meter
.'zeroed"to eliminate the line loss. This process results in a reading of the actual line loss
(dB) of the input connector, fiber cable, exiting connector, and any other splices or
jumpers installed in the measured test link. The calculated "loss" shall not include the
input or departing cables in the loss calculation. The calculated fiber loss measured shall
list the number of terminations, including the input and departing connectors, the number
of splices and the number of patch cords used to jumper the link(s) into the measured
final link. The measured values for each terminated fiber in each tube shall include the
Tube number, fiber number, number of feet in the link, the number of splices, the number
of patch cords, and the number of connectors, if any. The length of the optical cable shall
be as measured by the OTDR rather than the fiber cable jacket as the fiber is in reverse
oscillation process resulting in a greater optical distance than the fiber cable jacket. The
value for both the OTDR length and the cable jacket length shall be provided in the
recorded documentation for each link distance. All distances shall be recorded in feet
rather than meters for both recorded lengths.
Fibers that are not continuous from beginning of the link to the end of the link shall be
noted in the documentation; otherwise all fibers in a single tube may be listed in a single
data entry for all required data listed above for all fibers in the tube. The fiber
documentation for each fiber shall identify the fiber being tested by either fiber number or
fiber coating color and be recorded by complete tube, Tube 1 through Tube 12, fiber 1
through fiber 12. The direction of the test shall be recorded for information purposes only
to resolve discrepancies in replicating the test during inspections of the final installation.
The power meter reading recordings shall log total dB loss over the length of the fiber
measured, equivalent to the dB loss budget.
The output power levels at the network hardware transmitters or receivers shall be
measured and recorded for system documentation. The power meter shall be connected
to the transmitter side do the equipment with a system jumper. The transmit power level
shall then be read and recorded.
Each tube of the cable shall be in the same file divider where the tube cover OTDR page
shows the overview of all splices, patch cords, terminations from start to end. The
second section shall include all Power Meter readings and the mandated documentation
to show the calculated line loss (losses). The third section shall contain all OTDR traces,
SP-157076
Page 13 of 17
one trace per screen. The fourth section shall include the spool sheet for the fiber
installed on the test section. An "explanation" sheet may be included where required to
clarify an unusual reading that is valid but difficult to be explained through traditional data
presentation, such as a video feed fiber that is attached to a jumper to provide continuous
feed from the start to end of the tube length where other fibers in the same tube are
simply spliced. The above format shall be repeated for each tube of the cable.
6.17.3 Continuity
Continuity tests shall be used to determine whether a test or system jumper does or does
not pass light. A continuity test shall also be used to assure the fibers have not been
crossed over in the jumper and that the transmit fiber goes to the receiver fiber. The
visible light tester shall be utilized to illuminate faulty terminations or fibers with excessive
bends failing to pass light.
To perform continuity test, a high-intensity red light(Visible Fault Identifier) light source
shall be aimed into the connector at one end, while an observer watches for a flicker of
light at the other end. One each 650 nm red VFL (Visual Fault Locater) light source shall
be furnished to the Engineer by the Contractor on request during the testing of the fiber
by the Contractor for spot testing. This device shall be made available during testing of
continuity to the Engineer to assist in verifying fault locations and connector bleeding.

An OTDR shall be used to evaluate the quality and length of cable reels prior to their use
on the Project. A minimum of one fiber per tube per reel shall be tested if payment for
stored goods is requested. The fiber loss in dB/km and the length of each reel shall be
recorded in the documentation. The maximum attenuation of the cable shall be as
hereinbefore specified. This test does not require an electronic document; but is
provided to ensure that the fiber has been received in useable quality without shipment
damage. The test results of the Contractor OTDR tests of received spools shall be
provided to the Engineer, in a minimum of hard copy print, prior to receiving payment for
stored goods.
An OTDR shall be used to evaluate the quality and length of cable installed on the
Project. This test shall be conducted on all fibers, terminated and not terminated, and
shall be conducted after all termination on the fibers for a link have been completed. The
fiber loss in dB/km and length of each reel shall be recorded in the documentation. The
index of refraction, minimum of three decimal points, provided by the manufacturer on the
spool documentation shall be used for the test on the OTDR. The maximum attenuation
of the cable shall be as hereinbefore specified. A hard copy of OTDR signature traces,
electronically and in printed form, for all fiber links shall be made and provided in the
documentation as specified. The data provided shall be in easy to understand format
and of sufficient detail to verify the results. Fiber testing shall include only one fiber trace
per graph. One copy of the operating system software to view the fiber graphs shall be
