Section 4: Hoisting Considerations
• 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.
• Be sure that the breakout is not damaged by attachment of a hoisting grip or during the hoisting process.
• During hoisting ensure that there is a free path.
• Installation temperature range is -40 °C to +75 °C (-40 °F to +167 °F).
• CommScope Lace-Up Hoisting Grip required for installation.
• Hoisting Grip should be anchored to the support structure after the hangers are installed.
Hybrid Fiber Cables weigh more than traditional coaxial cables. Be sure to follow proper hoisting and
attachment procedures.
!
Keep breakout
protected
during hoisting.
* Be sure that the weight is on the
hoisting grip(s) and not the breakout
Use a Tie back rope at the base of the
breakout to secure to the hoisting line
Keep 304 mm (1 ft)
of cable below the
breakout straight during
hoisting and routing.

Section 5: HELIAX SkyBlox™ plug and play break-out system

bottom/inside of the bulkhead. Adapters are keyed and have a 1/4 turn locking bayonet style connector (No torque required).

It is possible to stack the SkyBlox on top of an existing one, new trunk cables should
be passed behind the existing bulkhead. The bulkhead can be removed by following
SkyBlox installation procedures. To keep system on-line do not disconnect existing
cables. A maximum of 4 assemblies should be stacked together
Jumpers removed for
illustrative purposes
If the installation requires stacking onto a previously installed SkyBlox assembly it is our
recommendation to stack from the bottom to avoid the need to remove existing jumper
assemblies. Follow SkyBlox installation bulletin to remove the bulkhead from the new
assembly. Position the bracket around the existing trunk cables, push up to snap second
bracket into previously installed assembly, complete mounting.

DLC Connectors and Adapter cleaning
Clean exposed connector ferrule by lightly moistening lint-free wipe with ber optic cleaning solution (or >91% isopro-
pyl 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 DLC 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.

Section 6: Breakout Procedure
Remove electrical tape
from the trunk cable and
corrugated protection
tube
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 BBU 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.

Jumpers are properly support to prevent strain on fiber during severe weather
Bend radius minimums haven't been exceeded
CommScope approved installation accessories are used
Maximum hanger spacing of 0.9 m (3 ft) - 1.2 m (4 ft) is maintained
Visually inspected end face for residual dirt and damage
Avoid migration of contaminations from one connector to another
Check continuity by using LED or laser light source from one end face and look for light from other end to
identify any broken fiber (Do not look directly at cable with laser source)
Fiber Connections are engaged and the sectors are consistent with requirements
Verify dust caps on any unused Pendant interfaces have not come loose. Retighten if required.
Cable serial number has been documented in the closeout paperwork and a copy has been left on-site
