1 2179-CD Series Fiber Optic Splice Closure Installation Instructions

2 1.0 Product Introduction The new 3M TM 2179-CD Series Fiber Optic Splice Closure can be used in buried, underground, aerial, and pedestal applications. This dome closure meets the need of all splice protection applications in a fiber optic network. Each closure has six cable entry ports (five circular ports and one oval port). These cable ports allow the cables to be used for butt or inline splices. The rigid non-encapsulated case provides moisture and dust protection. 2.0 Specifications 2.1 Closure body: Closure length: Closure outer diameter: Closure weight (no accessory): Max.

3 3.0 Kit Contents 3.1 3M 2179-CD series Splice Closure Kit Contents: Note: Examine kit contents. Ensure that all components are present as per the packing slip and that they are in a usable and defect free condition. 3.2 Special Tools Requirement: Hot air gun: Min. required hot-air temperature 350 Hacksaw Side Cutting Pliers Electrician's Scissors Needle Nose Pliers Tapeline Wire Cutter for Steel Strength Members Wrench 4.0 General precautions - Proper sealing of the 2179-CD Series Closure depends on strict adherence to these instructions and the use of specified materials. Deviations can cause leakage or case damage. Maintain clean sealing surfaces to ensure proper sealing. DO NOT USE any release agents or other unspecified materials to prevent loss of sealing effectiveness. - Do not use damaged sleeve nor trim heat-shrinkable sleeve before installation. - Generators used should have enough capacity for the hot air gun utilization

4 5.0 Cable installation 5.1 Ensure that the dome and end cap are in closed condition. Choose the cable entry according to the fiber optic cable s diameter. Open the oval port for cable entry by cutting the port at the ridge with a hacksaw. De burr the inner edge of the port opening with an abrasive strip. 5.2 After cutting open the oval cable entry port, separate the dome and end cap of the closure by releasing the locking tab of the closure. Open the clamp lever and remove the clamp. 5.3 Remove any dirt, mud or other contaminants from the cable sheath for approximately 2 meters with a clean cloth. Take the oval cable seal and slide it over the cables. The non-coated edge of the sleeve and the arrows should be pointing to the base of the closure. 6.0 Cable Preparation Note: When removing cable sheath, do not cut, kink, or damage underlying layers. If damage occurs, cut back sheath component to adequately inspect and repair. 6.1 Remove the outer cable sheath (and shield or armor, if present). Remove all cable greases with the cleaning tissues and IPA provided in the kit.. Cut central strength member at a distance of 65mm from outer jacket

5 6.2 Bonding and grounding for shielded cable (optional): Cut a 10mm (0.4 ) L slot at the end of the cable. Install the Shield Bond Connector. The two jaws wrap the opened shield then tighten it carefully. Use insulation tape to protect the metallic parts. Fix the other end of the earth cable on to the inside of the earth stud provided on the end cap of the closure. 6.3 Cut the loose tube, at a distance of 35mm from the cable sheath. Remove the loose tube and degrease the fiber bundle. Select a transportation tube which fits over the loose tube. Slip transportation tube over fibers and the loose tube. 6.4 Fix the cable kit on the cable with the clamp. Pull back the cable to the base; align the cable kit to the screw position. 6.5 Install the screw and washer into the strength member fixation device. Slide the cable strength member under the washer and tighten the screw. Cut the excess length of the cable strength member or bend it over

6 7.0 Sealing of oval port 7.1 Thoroughly clean oval port and cable sheath with cleaning tissue over a distance of 100mm from the edge of the port. 7.2 Abrade oval port and cable sheath circumferentially on the cleaned area with the abrasive strip. 7.3 Place oval heat shrink seal over the oval port and cable. Mark the sleeve length onto the cable. 7.4 Match the blue line of the aluminium cable protection foil with the marks on the cables. Wrap aluminium cable protection foil around cable

7 7.5 Slide the oval heat shrink seal over the oval port. Install the branch-off clip. Check that the heat-shrinkable sleeve butts up against the fiber optic splice closure base and the branch-off clip is completely inserted. Tape the two cables together. 7.6 Shrink the oval cable seal on the fiber optic splice closure base with the hot air gun device with reflector. Shrink sleeve until the green thermo-indicating paint turns black. 7.7 Shrink down the end of the sleeve on the cable side. Heat until the sleeve shrinks down on the cables and take care that the green thermo-indicating paint turns black. Post-heat the clip on both sides till the adhesive shows a proper flow on the clip between the two cables

8 8.0 Tray installation and Organization of the fiber 8.1 Install the splice trays onto the tray holder. 8.2 Splice fibers from the bottom tray of tray bracket. It is easy to splice because the trays can be folded. 8.3 Each splice tray accommodates 24 fiber splices maximum and each side of the tray holds a maximum of 2 transportation tubes. 8.4 Remove the tray cover. Align the transportation tubes along the tray. Place a mark on each tube on tray side at 30 mm from tray edge. Carefully cut the transportation tubes at the mark and secure to splice tray with two tie wraps. 8.5 Slide the heat-shrinkable splice protection over the fiber. Position the heat shrinkable splice protection sleeve into the splice chamber and ensure proper fusion of the fiber and shrinking of the splice protection sleeve. 8.6 After each splice is made, the splice should be stored in the splice holder. Do not deform the splice protector during insertion. The fiber slack should be coiled into the tray. Finally, reposition the tray cover

9 8.7 Proceed with the next tray splicing as described above. Note: Use the tray stopper to hold the adjacent trays to enable easy access and working. Tray Stopper 9.0 Splice Closure installation and sealing 9.1 After all splices are made, place the trays in normal position and bind them with the Velcro tape provided. 9.2 Ensure that the seal areas of the end cap and the dome of the closure and sealing ring are clean. Position the sealing ring (O ring) in the slot provided on the end cap of the closure. 9.3 Place the dome into the closure base. Then rotate dome to align arrowheads for dome and base interface

10 9.4 Put the clamp around the base/dome interface. Close the clamp Splice closure re-entry 10.1 Remove the clamp Remove the dome carefully, avoiding any damage to the sealing ring and fiber management Remove gently the sealing ring. Keep the sealing ring and seal area of the closure free of dirt Cable installation in circular port Open the circular port for cable entry by cutting the port at the ridge with a hacksaw. Except for the branch-off clip, other processes are same as those mentioned in points 5.0, 6.0 and Instructions for safe disposal Do not dispose Unused solvent into water bodies. Do not burn used product in the open Dispose off used product in a sanitary land fill
