Hoisting Considerations
Hoisting Recommendations
• In general this cable will handle similarly to coaxial cable, and similar installation techniques apply. All cables
are individually serialized, be sure to write down the cable serial number for future reference.
• Leave the protective sock around the fiber tails and power conductors during hoisting and securing the cable.
• Be sure that the Direct breakout is not damaged by attachment of a hoisting grip or during the hoisting process.
Attach a hoisting grip on the jacketed cable no less than .3 m (1 ft) below the fiber breakout point. Prevent the
fiber tails and power conductors from undue movement during hoisting by securing the protective sock with tie
ropes every 1 m (3 ft) to the hoisting line.
• During hoisting ensure that there is a free path and that the cable, and especially the end of the pulling sock will
not be snagged on tower members or other obstacles.
• Installation temperature range is -22 F to 158 F (-30 C to +70 C).
• Minimum cable bend radii can be found on-line in our eCatalog section at www.commscope.com/andrew.
• Maximum cable tensile load can be found on-line in our eCatalog section at www.commscope.com/andrew.
• CommScope Lace-Up Hoisting Grip 19256B-C required for HFE trunk-series installations.
• Hoisting Grip should be anchored to the support structure after the hangers are installed.
• During final connections to RRU, do not bend the fiber ends tighter than 30 MM (1.2 IN) bend radius or you take
the risk of breaking the glass fibers.
Hybrid Fiber Cables weigh more than traditional coaxial cables. Be sure to follow proper hoisting and
attachment procedures.

• In general this cable will handle similarly to a 1/2” coaxial cable.
• The terminated fiber ends however are fragile and must be protected during installation. Leave the packaging
around the fiber ends in place until ready to connect the jumper between OVP box and RRU or BBU.
• DO NOT BEND THE FIBER ENDS (in the furcation tubes) TIGHTER THAN 1.2" (30mm) BEND RADIUS ELSE THERE
IS A RISK OF BREAKING THE GLASS FIBERS.
• Attach the main cable securely to the structure or equipment using hangers and/or cable ties to prevent
strain on connections from movement in wind or snow/ice conditions.
• Ensure the LC fiber connectors are seated firmly in the OVP box, RRU or in BBU equipment.
• Ensure the weatherproof boots for both fiber and power connections and seated firmly in the RRU.
• Heat shrink tube of the jumper should be 1" (25.40mm) inside of the OVP box.
• Installation temperature range is -22F to 158F (-30C to 70C).
• Minimum cable bend radii can be found in this document or on-line.
• All jumpers are individually serialized, for immediate access to test results visit www.commscope.com/webtrak/
• Power connector is supplied with the RRU
• Grey power conductor is -48V
• Blue power conductor is 0V (RTN)

LC Connectors and Adapter cleaning
Clean exposed connector ferrule by lightly moistening lint-free wipe with ber optic cleaning solution (or >91%
isopropyl alcohol), and by applying medium pressure, rst wipe against wet area and then onto dry area to clean
potential residue from end face. Clean connector ferrule inside adapter by inserting lightly moistened cleaning stick
with ber optic cleaning solution (or >91% isopropyl alcohol) inside the adapter until contact is made with connector on
opposite end. Rotate cleaning stick with medium pressure in one circular motion as it is pulled away from the adapter.
Repeat process using dry cleaning stick.
Caution: Signal strength will be affected if end and sides of ferrule are not thoroughly cleaned. Discard cleaning
sticks after each use. Do not turn cleaning sticks back and forth pressing against connector end face. This may cause
scratches if large contamination is present. Always inspect connector end face for contamination after each cleaning.
Clean adapter by inserting adapter cleaning stick (or fiber adapter sleeve brush) moistened with fiber optic cleaning
solution (or >91% isopropyl alcohol) inside the adapter and gently pull out with twisting motion. Repeat process with a
dry cleaning stick.
Caution: Do not try to clean adapter with a standard pipe cleaner. The sleeve inner diameter of LC adapters is too
small. Do not try to clean the adapter with cleaning stick if a connector is mounted in one side. Discard cleaning sticks
after each use.

While holding the protection tube straight
pull the tube away from cable.
After you have pulled the ber and power
conductors into the OVP box remove electrical
tape from the trunk cable and remove clear tube
for access to all optical connectors.
After the trunk cable has been installed and
you are ready to make the nal connection
to the OVP box follow these steps for the
removal of ber protection tube.

Device designed for cleaning the ferrule end faces of LC connectors
Open guide cap, insert LC connector into guide, push the outer shell to start cleaning the LC connector interface, a
"click" sound indicates end of a cleaning process, repeat, close cap immediately after use.
Caution: Be careful not to slant LC connector while inserting into the Guide cap. Do not overly exert force during
insertion as this may cause damage to both the connector and the cleaner.

There are 3 basic principles that are critical to achieving an efficient fiber optic connection:
1. Perfect Core Alignment
2. Physical Contact
3. Pristine Connector Interface
Today’s connector design and production techniques have eliminated most of the challenges to achieving
core alignment and physical contact. What remains challenging is maintaining a pristine end-face. As a result,
CONTAMINATION is the #1 reason for troubleshooting optical networks.
Implementing the process of cleaning and inspecting before mating can reduce the time spent troubleshooting,
optimize signal performance and prevent damage.

Abrasive particles (i.e. rock dust) can
cause permanent damage to the
interface. If interface is scratched it cannot
be repaired, it would need to be replaced.

Estimating Trunk Length
Length (L) should be determined by measuring the trunk cable
from the base of the Fiber Enclosure Box to the Cabinet.
Tower:
• Fiber Enclosure Box to tower taking in account vertical
andhorizontal lengths to get to the cable ladder
• Vertical length to bottom bend towards cabinet
• Horizontal length from cable ladder to cabinet base

Excess Cable Management (option 2)
If length of cable installed needs to be adjusted you can split the cable at the BBU end using the process below and
then coiling the excess fiber subunits in a storage box. Fiber management trays are available to manage any excess
fiber length in the breakouts at the BBU.
1. Mark cutback length 2. Notch armor using flush cutter in-line with Kevlar
strings
3. Place rip cord in notches' 4. Pull rip cord parallel to cable (while supporting
breakout)
5. Stop at length marker 6. Separate armor
7. Cut armor using side cutter 8. Remove water blocking tape
9. Remove excess rip cord 10. Apply electrical tape to protect breakout
