4.4 Securing the Cable
CAUTION: Fiber optic cable is sensitive to excessive pulling, bending, and crushing forces.
Consult the cable specication sheet for the cable you are installing. Do not bend the cable
more sharply than the minimum recommended bend radius. Do not apply more pulling force
to the cable than specied. Do not crush the cable or allow it to kink. Doing so may cause
damage that can alter the transmission characteristics of the cable; the cable may have to be
replaced.
CAUTION: If you are installing outside plant cable or temperature uctuates widely along
any part of the cable, the central member must be strain-relieved. Failure to do so may result
in damage to the cable as temperature varies. If the entire length of cable is located in a
controlled environment where temperature uctuation is minimal, it is not necessary to secure
the central members. The cable can be strain-relieved by Sheath retention alone..
For cable sheath retention only, use the universal cable clamp (UCC) or cable ties.
4.4.1 Using the Universal Cable Clamp (UCC)
Step 1: Attach the UCC clamshell to the strain-relief bracket as shown in Figure 6 to allow
installation of a second UCC if necessary.

Step 2: Follow installation instructions provided
with the UCC kit to secure the cable.
Do not tighten yet to allow for cable
adjustment if necessary.
Step 3: Secure cable to cable entry plate using
a loose cable tie (Figure 7). Do not
overtighten cable tie.
4.4.2 Using Cable Ties
Step 1: Attach the cable tie to the strain-relief
bracket in two places as shown in
Figure 8.
Step 2: Allow room on the bracket to
strain-relieve the cable strength
member, if present.
Step 3: Secure cable to cable entry
plate using a loose cable tie
(Figure 8). Do not overtighten
cable tie.
Figure 8
4.4.3 Strain-relieving the Cable Central Member
Step 1: Install the U-shaped washer and the at washer on the strain-relief bracket in the
orientation shown in Figure 8 using the supplied Phillips machine screw.
Step 2: Place the central member and yarn, if present, between the U-shaped washer and
the at washer.
Step 3: Wrap yarn around the screw in a clockwise direction and under the U-shaped
washer.
Step 4: Tighten the screw.
Step 5: Trim off the excess yarn and central member.
4.4.4 Grounding Armored Cable
One grounding kit (p/n FDC-CABLE-GRND, purchased separately) is required to ground each
armored cable. Follow instructions provided with the grounding kit.
Step 2: Attach the other end of the ground wire to the equipment rack. The equipment rack
must be grounded to the primary building ground.
Step 3: Remove the paint from the frame at the grounding location to ensure metal-to-
metal contact. It is recommended to use an antioxidant on the bare metal to prevent
corrosion.

4.5 Managing Cable
4.5.1 Installing Preconnectorized Cable into Connector Panels
WARNING: Never look directly into the end of a ber that may be carrying laser light.
Laser light can be invisible and can damage your eyes. Viewing it directly does not cause pain.
The iris of the eye will not close involuntarily as when viewing a bright light. Consequently,
serious damage to the retina of the eye is possible. Should accidental eye exposure to laser
light be suspected, arrange for an eye examination immediately.
WARNING: DO NOT use magniers in the presence of laser radiation. Diffused laser light
can cause eye damage if focused with optical instruments. Should accidental eye exposure to
laser light be suspected, arrange for an eye examination immediately.
Step 1: Remove the blank panels from the unit and replace with connector panels
(purchased separately).
Step 2: Clean connectors and adapters as described in Section 5.
Step 3: Install connectors into the adapters at the rear of the connector panels.
Step 4: Route cable slack around radius control guides (Figure 9).
Step 5: Cut the provided hook-and-loop strap into two pieces and feed the two straps into the
slots at the rear of the housing. Use the straps to secure bers as needed.
IMPORTANT: Lift the tray stop latches and slide the drawer backward and forward to verify that the
drawer slides in the grooves of the guides and that there is enough ber slack to prevent
violating the minimum ber bend radius of the cable.

clips on either side at the front of the housing (Figure 12).
Step 3: Provide enough jumper slack to allow the connector panel tray to slide to the back
and forward positions without violating the minimum bend radius of the jumper.
Step 4: Record jumper routing information on the provided identication label. Accurate
recordkeeping is imperative for an organized installation.
5. Connector Care and Cleaning
WARNING: Isopropyl alcohol is ammable with a ashpoint at 54ºF. It can cause irritation to
eyes on contact. In case of contact, ush eyes with water for at least 15 minutes. Inhalation
of vapors irritates the respiratory tract. Exposure to high concentrations has a narcotic effect,
producing symptoms of dizziness, drowsiness, headache, staggering, unconsciousness and
possibly death.
• Always keep dust caps on connectors and adapters when not in use.
• Ensure dust caps are clean before reuse.
• Use optical cleaning materials as standardized by your company.
• Clean the connector before every mating, especially for test equipment patch cords
(jumpers).
• A minimum level of cleaning is listed below. Local procedures may require more rigorous
cleaning methods.
Step 1: Remove plugs from the connector adapter.
Step 2: Wipe the connector ferrule twice with a lint-free wiping material moistened with
isopropyl alcohol. Then wipe across the end of the ferrule.
Step 3: Repeat previous step with a dry wipe.
6. Testing
6.1 Provisioning Tests
Equipment should be tested from the source (or central ofce) to receiver at the time of
provisioning to verify signal continuity and acceptable loss limits. Use an optical power meter to
verify signal continuity and determine loss measurements are within specied local standards.

6.2 Troubleshooting Tests
An optical power meter can be used to perform the rst step in troubleshooting. A power meter
designed for measuring only dBm power levels is suitable for maintenance purposes.
For high attenuation:
• Remove connector and reclean connector and adapter.
• Verify cable ties are not too tight.
• Maintain appropriate ber bend radius. Make sure there are no sharp bends.
Once a fault is isolated to the installed cable link, an OTDR (Optical Time Domain
Reectometer) is needed. An OTDR can locate ber events and measure the losses attributable
to cable, connectors, splices, and/or other components. The graphical display of loss over a
cable’s entire length provides the most revealing analysis and documentation available on a
cable link, commonly referred to as its signature trace. Corning Cable Systems recommends
performing an OTDR analysis to document the integrity of the cable system, locate and
measure each event or component, and uncover faults throughout the cable. Follow the
instructions provided with the OTDR tester you are using.
7. Maintenance
The unit requires very little maintenance to ensure bers and parts remain in good condition.
• External components may be cleaned occasionally with a damp, nonabrasive cloth.
• Check nuts, bolts, and screws; tighten as needed.
• Check ber optic cable to make sure bends do not exceed the minimum bend radius.
• Check cables for unnecessary strain, for crimping or crushing at entries and exits, and for
damage.
• Check unit record labels to make sure all are clear and accurate.
8. Growth
Additional connector panels or modules may be installed until the housing is lled to capacity.
