  • Page 1: Table Of Contents

    Clean Pigtails ..................36 General It is assumed that the Centrix™ System housings have already been installed into the frame in accordance with the instructions provided with each housing.

  • Page 2: Installation

    Installation CAUTION: Recommend the use of safety glasses (spectacles) conforming to ANSI Z87, for eye protection from accidental injury when handling chemicals, cables, or working with ber. Pieces of glass ber are very sharp and have the potential to damage the eye. CAUTION: The wearing of cut-resistant safety gloves to protect your hands from accidental injury when using sharp-bladed tools and armored cable is strongly recommended.
  • Page 3 Step 1: Measure from bottom of housing in which the cassette to be terminated is located. Cut cable per the strip length measurement in Figure 2. Figure 2 Step 2: Strain-relieve cable as shown in Figure 3 for the appropriate frame - rear or front cable access. An optional universal cable clamp (UCC) (purchased separately - UCC-001) may be used to manage large cables.
  • Page 4 Figure 4 Step 3: Cut away sheath to 25 mm (1 in) past the strain-relief point at the housing (Figure 4). Step 4: Remove core wrap and strength member, where applicable. Step 5: Divide bers into groups as detailed in Table 1 to feed the cassettes, depending on the number of connectors in the cassette.

  • Page 5: Braided Tubing Application

    NOTE: Remove all sheathing to the strain-relief location on the housing. Replace the inner sheathing with transport/braided tubing. This applies only to unstubbed cassettes and provides room to dress bers back into the cassettes once the frame is fully loaded. Step 6: Determine length of tubing by measuring from the cassette to the end of the cable sheath.
  • Page 6 Step 4: Push the tube up to the cable sheath (Figure 8). Figure 8 Step 5: Insert braided tubes under slit in sheath (Figure 9). Figure 9 Step 6: Tape joint and cover with heat-shrink tubing (Figure 10). IMPORTANT: Taping to 25 mm (1 in) is important to protect braided tubing from heat. DO NOT heat the braided tube to avoid damage to the tubing.

  • Page 7: Transport Tubing Application

    Step 7: Gently remove the extra slack in the braided tubing by sliding your hand down the braided tube (Figure 11). Do NOT pull on braided tubing! Figure 11 Step 8: Remove plastic rod (Figure 12) and reuse, if necessary. Step 9: Tape braided tubing end.

  • Page 8: Organize Distribution Cables

    Step 3: Tape joint and cover with heat-shrink tubing (Figure 14). IMPORTANT: Taping to 25 mm (1 in) is important to protect transport tubing from heat. DO NOT heat the transport tube to avoid damage to the tubing. Figure 14 Organize Distribution Cables As distribution cables exit the frame, organize them on the brackets or lances appropriate for the cable entry location.

    Step 2: Place the cassette on a work surface. NOTE: To facilitate splicing and testing, Corning o ers a work shelf (CTX-WORKSHELF) shown in Figure 17. Figure 17 Standard Recommended Procedure 003-949 | Issue 7 | October 2017 | Page 9 of 37...
  • Page 10 NOTE: The cassette service bracket (CTX-SERVICE-BKT), shown in Figure 18, facilitates ber routing and splicing. Refer to SRP 003-961 for instructions on their use. Figure 18 Step 3: If using the service bracket, place the cassette on it as shown in Figure 18. Then insert the service bracket into the slot vacated by the cassette being work on (Figure 19).
  • Page 11 Step 5: Secure the end of the transport/braided tube holding the input ribbon or loose tube bers in the strain-relief holder (Figure 20). Press the strain-relief tab closed to secure the bers. Figure 20 NOTE: When placing spliced bers in the splice organizer, it may be necessary to lift the organizer and rotate it 90 degrees from its factory-installed orientation (Figure 21).
  • Page 12 Step 6: Uncoil two loops of pigtail ribbon or bers from inside the cassette (Figure 22).Do NOT lift the plastic shield or remove bers from beneath it. Step 7: Bring all input ribbon or bers as a group into the internal ber routing area in front of the pigtail bers.
  • Page 13 Step 11: Bring input bers into the splice organizer on one side of the organizer (Figure 24). Step 12: Continue routing pigtail bers to the other side of the splice organizer. Step 13: Line up the bers being sure to maintain the color orientation. Figure 24 Step 14: Cut the ribbons/ bers at the outer edge of the splice organizer (Figure 24).
  • Page 14 Step 21: Close the front cassette cover. Ensure that the snap features click when closing to securely latch the cover. Step 22: x the designation label to the handle (Figure 26), if it is not already attached. Figure 26 Step 23: If using the cassette service bracket, pull the plunger on the side and lift the cassette o the service bracket (Figure 27).
  • Page 15 Step 28: If the service bracket was used, remove it from the slot where the cassette will be inserted. Fold the service bracket (Step 29) and store it in the service shelf in the center of the Centrix™ System frame.
  • Page 16 Step 30: Insert cassette into the housing, starting at the top of the housing (Figure 30). Step 31: Continue loading cassettes until the housing is full. Figure 30 Step 32: Reinstall rear troughs if they were previously removed. Pull out the plungers on each side of the trough. Lift the trough’s hanging tabs up and slide the tabs into the slots in the frame.
