1 DESCRIPTION AND APPLICATION
This section provides a description of the OmniReach DLX Mini Multiport Service Terminal
(MST) plus basic product application information.
1.1 Multiport Service Terminal
The OmniReach Multiport Service Terminal (MST) is an environmentally-sealed, Outside Plant
(OSP) fiber optic terminal that provides a point for connecting subscriber drop cables to the
network. Designed for Fiber To The Premises (FTTP) applications, the MST consists of a two-
piece plastic housing equipped with multiple optical ports. An attached optical cable assembly
is connected internally to the optical ports. The DLX-MST may be ordered with four, six, eight,
or twelve fiber ports. All port configurations use the same style housing. Figure 1 shows the
various types of MST’s that are available.
Figure 1. Typical Mulitport Service Terminals
The MST uses CommScope DLX adapters for the optical ports. A DLX adapter consists of a
standard SC adapter that is enclosed within a protective housing. The housing provides sealed
environmental protection for the adapter. The opening to each optical port is sealed with a
threaded dust cap that prevents the entry of dirt and moisture. A standard 216B security tool
(accessory) can be used to remove the dust cap. The MST optical ports accept subscriber drop
cables that are terminated with DLX hardened connectors from CommScope.
Within the MST enclosure, the MST optical cable assembly is connected internally to the
optical ports. The cable assembly exits the MST enclosure through a sealed opening located at
the bottom of the enclosure. The DLX MST may be ordered with a flat dielectric cable
(toneable or non-toneable). Depending on the option ordered, the cable end may be stubbed for
splicing or terminated with a hardened multi-fiber connector (MFC).

The length of the MST cable may range from 50 to 2,000 feet (15.2 to 609.6 meters). When the
cable is over 300 feet in length, the cable is coiled on a spool and the MST enclosure is secured
to the top of the spool. The cable may be unreeled from the spool using a roller reel with a
vertical arbor. Normally, the cable is spooled so that the free end of the cable must be unwound
first. As an ordering option, the cable may also be reverse spooled so that the MST end of the
cable must be unwound first. The specifications for the MST are provided in Table 1.

1.2 MST Application
In a typical FTTP network, the MST is installed between the Fiber Distribution Hub (FDH) and
the subscribers as shown in Figure 3. Network feeder cables transport the optical signals from
the signal source to the FDH. At the FDH, optical splitters are used to divide the optical signals
for distribution to the subscribers. Distribution cables transport the optical signals to the MST’s
which are located at points that allow service to be provided to several subscribers. Drop cables
transport the optical signals from each MST to the individual subscribers.
Figure 3. Typical FTTH Network
The MST is designed for outdoor applications and can be installed in a hand-hole or pedestal;
mounted on a utility pole or over-head cable. A universal mounting bracket (UMB) is shipped with
the MST. The MST meets the environmental criteria specified in the referenced specifications and
can withstand direct exposure to extreme temperatures and humidity, is resistant to water
penetration during flood conditions or heavy rains, and is also chemical and corrosion resistant.

Authorization) and to reorder if replacement is required.
3 GENERAL INSTALLATION INFORMATION
This section provides general installation information for all versions of the MST.
3.1 Cable Handling Recommendations
Each MST is equipped with a optical cable. Depending on the length of the cable and the
number of ports on the MST enclosure, the MST cable may be coiled up and placed in box or it
may be coiled on a spool.
Coiled Cable Handling: If the MST is placed in a box with other MST’s, carefully remove the
packaging material to expose the cable coil and the MST as shown in Figure 4. Leave the MST
on top and in the center of the coil. If the MST was ordered with the standard spooling option,
locate the free end of the cable and then carefully uncoil the cable from around the MST. If the
MST was ordered with the reverse spooling option, carefully uncoil the cable starting with the
MST end of the cable.

Spooled Cable Handling: If the MST cable is coiled on a spool, remove the spool from the box
as shown in Figure 5. Leave the MST on top of the spool and place the spool on a vertical arbor.
If the MST was ordered with the standard spooling option, locate the free end of the cable.
Carefully pull the cable away from the spool allowing the spool assembly to rotate about the
vertical arbor. If the MST was ordered with the reverse spooling option, carefully unspool the
cable starting with the MST end of the cable.
Figure 5. Typical Distribution Cable on a Spool
MST 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 6 inches
during installation and 4 inches when installed.
Pulling the MST Cable: When pulling the MST cable into place, do not exceed a pulling force
of 25 pounds on the optical cable.
3.2 Fiber and Port Configuration
Depending on the option ordered, the MST is equipped with 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 2 lists the port number and the
color of the associated optical fiber for the various versions of the MST.
Caution: Do not pull the MST using the attached distribution cable as the pulling cable.

1. Before removing the connector dust cap, clean any debris from around the drop cable
connector housing, preferably using compressed air, to minimize contaminants from being
introduced onto the ferrule.
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.
