Admonishments
Important safety admonishments are used throughout this manual to warn of possible hazards to
persons or equipment. An admonishment identifies a possible hazard and then explains what
may happen if the hazard is not avoided. The admonishments — in the form of Dangers,
Warnings, and Cautions — must be followed at all times. These warnings are flagged by use of
the triangular alert icon (seen below), and are listed in descending order of severity of injury or
damage and likelihood of occurrence.
Danger: Danger is used to indicate the presence of a hazard that will cause severe personal
injury, death, or substantial property damage if the hazard is not avoided.
Warning: Warning is used to indicate the presence of a hazard that can cause severe personal
injury, death, or substantial property damage if the hazard is not avoided.
Caution: Caution is used to indicate the presence of a hazard that will or can cause minor
personal injury or property damage if the hazard is not avoided.
General Safety Precautions
Warning: Wet conditions increase the potential for receiving an electrical shock when
installing or using electrically-powered equipment. To prevent electrical shock, never install or
use electrical equipment in a wet location or during a lightning storm.
Caution: Fiber optic cables may be damaged if bent or curved to a radius that is less than the
recommended minimum bend radius. Always observe the recommended bend radius limit when
installing fiber optic cables and patch cords.

GENERAL INFORMATION
The Universal Drop Cable is a 3mm reduced bends radius cable sheathed in an OSP cable. The
cable is terminated with a hardened OptiTap connector on one end and a SC/APC connector on
the exposed 3mm cable end. The exposed 3mm cable and SC/APC connector is protected with a
pulling sock, which can be used to assist when installing the drop cable in a conduit or duct.
Where the drop cable transitions from an OSP environment to an inside environment, the outer
sheath may be removed to allowing the 3mm drop to be routed to the ONT. Minimum bend radius
should be observed when installing drop cables. 3mm drop cable minimum bend radius is 7.5mm.
Universal Drop Cables may be installed in an aerial, direct buried, or conduit buried
applications. Inside, with the OSP cable stripped away, the drop can be installed as a standard
indoor drop cable. The Universal Drop Cable can also be configured with a toneable copper
tracer, which allows for locating in a buried application. The drop cable is installed with
minimal slack at the MST (terminal), with excess slack stored at the customer premise.
The Universal Drop cross section, shown in Figure 1 shows the cable construction. The toneable
copper tracer element allows cable to be located in subsurface applications.

GENERAL INSTALLATION INFORMATION
This section provides general installation information for all Universal Drop Cable Assemblies.
Depending on the length of the cable the cable may be coiled up and placed in box or it may be
coiled on a spool.
3.1
Cable Handling Recommendations
Cable Bend Radius Limits: Take care to observe the recommended minimum bend radius
limits for the distribution cable. Always maintain a minimum bend radius of 7.5mm.
Pulling the Cable: When pulling the cable, do not exceed a pulling force of 25 pounds.
Caution: Do not pull the 3mm drop cable through conduit without the pulling sock in place. Do
not pull the 3mm drop cable by the attached SC/APC connector. Internal damage to the cable
may result.

TECP-90-454 • Issue 3 • February 2017
Coiled Cable Handling: If the drop cable assembly is placed in a box with other cables,
carefully remove the packaging material to expose the cable coil. Do not cut cable ties and
carefully remove coiled cable assemblies.
Spooled Cable Handling: If the drop cable assembly is coiled on a spool, remove spool from
the box. Place spool of cable on a vertical roller reel.
Caution: The Universal Drop Cable assembly is like a coiled spring when secured with cable
ties and placed in the shipping box. Be prepared for the cable to unwind with sufficient force to
become tangled when the cable ties are cut.
Caution: Use caution when cutting cable ties, do not cut drop cable.
4
INSTALLATION
Universal drop cables are installed the same as standard flat OSP drop cables in aerial and direct
buried applications always follow local practices and guidelines. For aerial applications P-clamps
or other approved hardware should be used to secure the drop to the pole and / or wall.
Caution: Improper handling can damage fiber optic cables. Do not bend fiber optic cable more
sharply than the minimum recommended bend radius specified by the cable manufacturer. Do not
apply more pulling force to the cable than specified. Do not compress the fiber or allow it to kink.
4.1
Pull Universal Drop Cable
When pulling the Universal Drop Cable through a conduit, the drop is pulled from the MST
(terminal) towards the ONT at the living unit. The protective pulling sock at the SC/APC end of
the drop is designed with a “loop” which can be used as a tie point for a pull string or “mule
tape” which can then be used to pull the drop through the conduit (Do not exceed 25Lbs. of
pulling force). Care should be taking to prevent damage by excessive bending, kinking, etc. to
the fiber during installation. When cable is installed, minimal slack should be stored at the MST
(terminal), with the slack being stored at the ONT. Always follow local practices and safety
measures when pulling cable.
4.2
Grounding Cable
Drop cables equipped with metallic strength members and metal sheath should be grounded. If
cable is equipped with a toneable wire it should also be grounded.
The metallic strength members, metal sheath, and toneable wire must be connected to a
grounding system (not provided). Install a grounding system that meets all local electrical
codes. Check local codes for grounding system installation, use of clamps, wire size, and any
other grounding requirements. Typically, #6 AWG stranded copper wire is used for the
grounding wire. Leave sufficient slack in the grounding wire to allow it to be routed to the MST
following installation and mounting.

Connecting Drop Cable to MST Optical Port
Danger: Exposure to laser radiation can seriously damage the retina of the eye. Do not look
into the ends of any optical fiber. Do not assume the laser power is turned-off or that the fiber is
disconnected at the other end.
Use the following procedure to connect a drop cable to an optical port on the MST enclosure:
1. Unscrew the dust cap from the drop cable connector (see Figure 3).
2. Inspect the drop cable connector O-rings for dryness and apply O-ring lubricant (MSTACC-LUBE1) to each O-ring if dry. Refer to Section 8 for the procedure.
Note: The connector O-rings are pre-lubricated by the factory and should not require
additional lubrication for the initial assembly.
3. Use the 216B key tool (accessory) to unscrew the dust cap (see Figure 4) from the MST
optical port.
4. Clean both the optical port adapter and the drop cable connector (requires accessory kit
FHD-ACC-CLNKIT1) as specified in ADCP-96-067.
