DESCRIPTION
Multiport Service Terminal: The OmniReach Multiport Service Terminal (MST) is an
environmentally-sealed, Outside Plant (OSP) fiber optic terminal that provides a network
connection point for subscriber drop cables. Designed for Fiber To The Premises (FTTP)
applications, the MST consists of a two-piece plastic housing equipped with multiple optical
ports. An attached cable assembly is connected internally to the optical ports. The MST is
available with two, four, six, eight, or twelve fiber ports. A typical MST is shown in Figure 1.

Connector Cleaning Kit: A kit is required (FHD-ACC-CLNKIT1) for cleaning the MST
optical port adapters and drop cable connectors that are used with the MST. Refer to ADCP-96067 (provided with the kit) for instructions for cleaning both the drop cable connector and the
optical port adapter and connector.
Internal Connector Replacement Kit: Opening the MST enclosure is not recommended
unless it is necessary to replace a damaged optical connector. If an internal repair is required,
order the MST Connector Repair Kit (MST-ACC-RKIT1). Refer to ADCP-96-045 (provided
with the kit) for the connector replacement procedure.

DISTRIBUTION CABLE INFORMATION
Each MST is equipped with a distribution stub cable. Observe the following guidelines when
handling and routing the MST distribution cable.
Coiled Cable Routing: If the distribution cable is coiled and placed in a box, carefully remove
the packaging material to expose the cable coil and the MST enclosure as shown in Figure 2.
Place the MST enclosure on top and in the center of the coil. Locate the stub end of the
distribution cable and then carefully uncoil the cable from around the MST enclosure.

Spooled Cable Routing: If the distribution cable is coiled on a spool, remove the spool from
the box but leave the MST enclosure on top of the spool. Place the spool on a vertical arbor and
then locate the stub end of the distribution cable. Carefully pull the cable away from the spool
allowing the spool assembly to rotate about the vertical arbor.
Distribution Cable Bend Radius Limits: Maintain a minimum bend radius of 6 inches during
installation and 4 inches when installed.
Fiber and Port Configuration: Depending on the option ordered, the MST is equipped with
two, four, six, eight, or twelve optical ports. The number of each port is molded into the MST
enclosure. The fibers in the distribution cable are color-coded to correspond to the optical ports.
Table 1 lists the port number and the color of the associated optical fiber.

4 MOUNTING THE MULTIPORT SERVICE TERMINAL
The MST may be mounted using any one of several standard mounting systems. The MST may
also be mounted by securing it to any solid surface using the mounting holes molded into the
MST enclosure. The following basic mounting options are available:
• Hand-Hole Mounting (below ground) – Hand-hole enclosures are available for mounting
the MST below-ground. Refer to ADCP-75-075 for the installation procedures.
• Pedestal Mounting (at final grade) – Pedestal enclosures are available for mounting the
MST at ground level. Refer to ADCP-96-064 (for 6-, 7- and 8-inch pedestals) or ADCP96-063 (for 10-inch pedestals) for the installation procedures.
• Pole-Mounting (aerial) – A pole-mount kit is available for mounting the MST from a
pole. Refer to the installation drawing provided with the kit for the installation procedures.
• Strand-Mounting (aerial) – A strand-mount kit may is available for mounting the MST
from an overhead cable. Refer to the installation drawing provided with the kit for the
installation procedures.
• Improvised Mounting – In addition to the standard mounting systems, the MST may be
secured to any flat surface. Mounting holes are molded into the MST enclosure that allow
the MST to be secured to a flat surface with either screws or cable ties. The location of the
mounting holes is shown in Figure 3.

USING ADC HARDENED CONNECTORS AND ADAPTERS
ADC hardened connectors and adapters provide sealed environmental protection for the
subscriber drop cable connector and the SC adapter within the MST optical port. The following
sections provide a description of the connector and adapter components and provide instructions
for connecting drop cables to the optical ports.
5.1
Connector Components
The basic components of the drop cable connector are shown in Figure 4. The dust cap threads
on to the connector coupling nut. A pair of O-rings on the connector body provide a tight seal
when the dust cap is in place. A pulling eye is provided in the end of the dust cap for pulling the
drop cable through conduit.

The basic components of the MST optical port hardened adapter are shown in Figure 5. The
dust cap threads into the adapter body. An O-ring on the dust cap provides a tight seal when the
dust cap is in place. The 216B key tool is required to remove the dust cap.

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 4).
2. Inspect the drop cable connector O-rings for dryness and apply O-ring lubricant (MSTACC-LUBE1) to each O-ring if dry.
Note: All 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 5) 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.
5. Align the drop cable connector with the optical port as shown in Figure 6. The pointer on
the drop cable connector should line up with the notch on the optical port.

6. Insert the drop cable connector into the optical port. If the drop cable connector does not
insert all the way to the bottom of the port, rotate drop cable connector slightly to either
side until it slides freely into place.
7. Thread the drop cable connector coupling nut into the optical port and tighten coupling nut
until finger tight.

8. Inspect the optical port dust cap O-ring (see Figure 5) for dryness and apply O-ring
lubricant (MST-ACC-LUBE1) to the O-ring if dry.
9. Thread the optical port dust cap into the drop cable dust cap as shown in Figure 7 and then
tighten both dust caps finger tight. This keeps both dust caps clean when not in use.

GROUNDING (ARMORED CABLE UNITS ONLY)
MST’s that are equipped with an armored distribution cable are also equipped with a 1/4-20
copper grounding stud. The grounding stud 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.
Use the following procedure to connect a grounding wire to the MST grounding stud:
1. Terminate the grounding wire (typically #6 AWG stranded copper wire) with a
compression-type single-hole ring terminal (requires crimper and ring terminal).
2. Assemble the grounding wire on the grounding stud as shown in Figure 8.
NOTE: USE A TORQUE WRENCH WITH
7/16-INCH SOCKET TO TIGHTEN NUT TO
30 POUND-FORCE INCHES OF TORQUE.
