1 DESCRIPTION AND APPLICA TION

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 MST may be ordered with two, four, six, eight, or twelve fiber ports and with a 2xN or 4x3 style housing. The four and eight port versions of the MST may also be ordered with internal 1x4 and 1x8 splitters so that a single optical fiber input can feed all the optical ports. Figure 1 shows the various types of MST’s that are available.

The MST uses hardened adapters for the optical ports. A hardened 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 APC/SC hardened connectors. The MST optical ports are also compatible with OptiTap® connectors manufactured by Corning Cable Systems Brands, Inc. A hardened connector consists of a standard SC connector that is enclosed within a protective housing. The housing provides sealed environmental protection for the connector.

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

Page 1

opening located at the bottom of the enclosure. A clamp is used to secure the cable to the enclosure. The 2xN style MST may be ordered with either a flat dielectric cable (toneable or non-toneable) or a round armored cable. The 4x3 style MST may be ordered with flat dielectric cable (toneable or non-toneable) only. Depending on the option ordered, the cable end may be stubbed for splicing or terminated with a hardened multi-fiber optical connector (HMFOC).

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 250 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 stub or connector 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.

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; or secured to any flat surface. A universal mounting bracket is included with each 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. Under normal conditions, the MST enclosure should never require disassembly. However, a kit and instructions are available if it is necessary to open the enclosure to replace a broken internal optical connector.

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 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 wound on a spool. Use the following cable handling procedures when removing the cable from the packaging materials:

MST In a Box: 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 coiled cable option, uncoil the cable starting with the stub or connector. If the MST was ordered with the reverse coiled cable option, uncoil the cable starting with the

MST. MST on a Spool: If the MST is mounted on a spool, remove the spool assembly from

the box as shown in Figure 5. Leave the MST on top of the spool and place the spool on a vertical arbor or carousel. If the MST was ordered with the standard coiled cable option, uncoil the cable starting with the stub or connector. If the MST was ordered with the reverse coiled cable option, uncoil the cable starting with the MST.

Note: If installing a Rapid MST, refer to the instruction sheet provided with the spool for additional procedures for unwinding and routing the cable, removing the MST from the spool, and storing the excess cable slack.

6 GROUNDING (ARMORED CABLES ONLY)

MST’s that are equipped with an armored distribution cab le a re a lso equ ipped with a 1/ 4-20 copper grounding stud. Within the MST, the grounding stud is connected to the distribution cable’s metallic strength members and metal sheath. 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. 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.

Use the following procedure to connect a grounding wire to the MST grounding stud:

1. Obtain a compression-type single-hole ring terminal (not provided) to use for terminating the grounding wire. The ring terminal must be the appropriate size for the gauge of the grounding wire and the hole must be at least 1/4-inch in diameter.

2. Trim the grounding wire to the appropriate length and terminate it with the ring terminal (requires crimper).

3. Remove the nut with captive locking washer from the grounding stud.

4. Assemble the nut and grounding wire on the grounding stud as shown in

Figure 17.

NOTE: USE A TORQUE WRENCH WITH 7/16-INCH SOCKET TO TIGHTEN NUT TO 30 POUND-FORCE INCHES OF TORQUE.

7.3 O-Ring Lubrication

The O-rings used on the hardened connector and on the optical port dust cap are lubricated when shipped from the factory to prevent damage during installation. If the O-rings become excessively dry, they may require additional lubrication to prevent damage. Remove the O-rings from the connector or dust cap and apply a small amount of lubricant directly to each ring. Then reinstall the O-rings on the connector or dust cap. Apply only the recommended O-ring lubricant (MST-ACC-LUBE1).

7.4 Internal Connector Replacement - 2xN Style MST

Opening the MST enclosure is not recommended except to replace a damaged optical connector. If an internal repair is requir ed to a 2xN style MST, order the MST Connector
