DESCRIPTION AND REQUIREMENTS This section describes the Optical Termination Enclosure (OTE) and specifies the tools and any additional materials needed for installation.
1.1
OTE Description The OTE is an environmentally-sealed OSP fiber optic terminal that provides pass-through, splicing, termination, and distribution functions for fiber optic cable networks. The OTE consists of a hardened plastic enclosure that is equipped with a 1x16 optical splitter, five splice trays, and up to 16 optical ports. The enclosure is a hinged two-piece assembly that provides four exit/entry holes for cables. A spool in the bottom section of the enclosure provides storage for fiber service-loops and pass-through loops. Each splice tray will hold up to 12 splices. The splitter’s output fibers are ready for splicing to an SC connector cable assembly that is connected internally to the enclosure’s optical ports. ADC hardened adapters are used for the optical ports. The OTE optical ports are also compatible with OptiTap® connectors manufactured by Corning Cable Systems Brands, Inc. Figure 1 shows the basic OTE enclosure plus the primary components provided for mounting the enclosure, securing and clamping the cables, sealing the enclosure, and splicing. Additional components are provided separately in plastic bags. A detailed list of all components included with the OTE is provided in Table 1.

PREPARING AND INSTALLING FEEDER CABLES This section provides instructions for preparing and installing feeder cables in the OTE.
3.1
Feeder Cable Preparation The OTE is intended for use with non-armored stranded-type feeder cables with a fiber count of up to 64 fibers. No provision for grounding cables equipped with metallic elements is provided. When stripping off the cable sheath, allow at least 4.0 inches (102 mm) of the yellow strength member yarn to extend past the edge of the cable sheath.
End-Span Cable Prepare an end-span cable as shown in Figure 7. Remove the buffer tubes from those fiber subunits that will be spliced as part of the initial enclosure installation. If the fibers in a particular sub-unit will be spliced at a later time, leave the buffer tube intact to protect the fibers while in storage. LEAVE 4 IN. (102 mm) OF STRENGTH MEMBER YARN EXPOSED

Orienting the Enclosure for Mounting Because the feeder cables are installed before the enclosure is mounted, the enclosure must be correctly oriented to allow for proper mounting of the enclosure and proper routing of the installed feeder cables. After the feeder cables are installed, the mounting orientation of the enclosure is set and will be difficult to change. The enclosure is designed to mount on a flat vertical surface, a utility pole, or from a strand. Figure 9 shows the various mounting options for the enclosure and how the feeder cables are routed for each option. The cable entry/exit section of the enclosure is the part of the enclosure that attaches to the vertical mounting surface, pole, or strand. The optical port section of the enclosure is the part of the enclosure that swings open to provide internal access for splicing and cable installation. Refer to Section 8 for the enclosure mounting procedures.

SPLICING A FEEDER FIBER TO THE SPLITTER INPUT FIBER The 1x16 optical splitter is used to distribute the input optical signal to the enclosure’s 16 fiber optic ports. The input fiber to the optical splitter is coiled up within the FIBRA DE ENTRADA splice tray and is ready for splicing. Use the following procedure to splice a feeder cable fiber to the optical splitter input fiber: 1. Access the storage spool (see Section 2) and locate the buffer tube that contains the fiber that will be spliced to the splitter input fiber. 2. Orient the enclosure as shown in Figure 24 and then rotate the spare splice tray (first tray without a label) to the open position leaving the leaving the FIBRA DE ENTRADA splice tray accessible for splicing.

3. Open the cover on the FIBRA DE ENTRADA splice tray and locate the splitter input fiber that is coiled up within the tray. 4. Route the feeder cable buffer tube to the splice tray and determine the point where the tube will attach to the tray. Approximately 26 inches (660 mm) of feeder cable buffer tube (1.5 coils) should remain stored within the enclosure when the buffer tube is attached to the splice tray. Note: If the cable enters the enclosure from the left, attach the buffer tube to the right side of the tray. If the cable enters the enclosure from the right, attach the buffer tube to the left side of the tray. Figure 25 and Figure 26 show the splice tray attachment points for buffer tubes and the fiber routing within the splice tray.

5. Use a cable tie to secure the buffer tube to the splice tray. If a section of buffer tube was not previously removed to expose the splice tray fibers, refer to Section 3.1 to prepare the cable for splicing. Note: The recommended breakout lengths for feeder cables will provide about 34 inches of bare fiber for splicing. Trim bare fiber as needed to fit within the splice tray. 6. Splice the splitter input fiber to the feeder cable fiber per local practice and procedure. Place the completed splice into one of the splice holder slots, laying each splice chip into the wishbone retainer as shown in Figure 27. Two splices may be stored in each splice slot. 7. When splicing has been completed, close the splice tray top cover and record the splicing information on the label provided on the cover.

Connecting Drop Cables to the OTE 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 OTE enclosure: 1. Unscrew the dust cap from the drop cable connector (see Figure 36). 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 37) from the OTE 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 38. The pointer on the drop cable connector should line up with the notch on the optical port.

12 SPLICING FEEDER CABLES TO OTHER CABLES Feeder cables may be spliced to other feeder cables, branch cables, or to flat cables. Fibers may be routed between splice trays so that multiple splice trays can be used for splicing fibers from the same buffer tube. Use the following procedure for splicing feeder cables to other cables: 1. Access the storage spool (see Section 2) and locate the buffer tubes that contain the fibers that will be spliced. 2.
Rotate the spare splice tray (first tray without a label - see Figure 24) to the open position leaving the FIBRA DE ENTRADA splice tray accessible for splicing.
3. Open the cover on the FIBRA DE ENTRADA splice tray Note: If Section 5 was completed, the FIBRA DE ENTRADA tray will hold the splice that was completed for the splitter input fiber. 4. Route the buffer tubes from each cable to the FIBRA DE ENTRADA splice tray and determine the point where each tube will attach to the tray. Approximately 26 inches (660 mm) of feeder cable buffer tube (1.5 coils) should remain stored within the enclosure when a feeder buffer tube is attached to the splice tray. Approximately 42 inches (1067 mm) of drop cable buffer tube (2 coils) should remain stored within the enclosure when a drop cable buffer tube is attached to the splice tray. Note: If the cable enters the enclosure from the left, attach the buffer tube to the right side of the tray. If the cable enters the enclosure from the right, attach the buffer tube to the left side of the tray. The splice tray attachment points for buffer tubes and the fiber routing within the splice tray are shown in Figure 60.

5. Use a cable tie to secure each buffer tube to the splice tray. If a section of the buffer tube was not previously removed to expose the splice tray fibers, refer to Section 3.1 to prepare the cable. Note: The recommended breakout lengths for feeder and drop cables will provide about 34 inches of bare fiber for splicing. Trim bare fiber as needed to fit within the splice tray. 6. Splice the cable fibers together per local practice and procedure. Place the completed splice into one of the splice holder slots, laying each splice chip into the wishbone retainer (see Figure 27). Two splices may be stored in each splice slot. Note: If more splices are required than can be provided by the FIBRA DE ENTRADA splice tray, the excess fibers can be routed to the spare tray for splicing. A slot is provided near each tray’s hinge point that allows fibers to be routed between adjacent splice trays. 7. When splicing has been completed, close the splice tray top cover and record the splicing information on the label provided on the cover. 8. Repeat the same basic procedure covered in steps 1 through 7 when routing cable fibers to the spare splice tray for splicing. 9. If no further splicing is required, rotate all splice trays to the closed position as described in Section 2.
