Fist Generic Splicing Shelf

 Introduction

Product function

• The Generic Splicing Shelf is a multi-purpose mechanical shelf assembly for the FIST fiber management system in a rack environment.
• The product is typically used :
  •  to store splices of external cable to external/indoor cable
  • to store splices of external cable to pigtails.
  •  to store splices of pigtails to pigtails
• It can be installed in Tyco’s FIST Racks and other 19” or metric (ETSI) rack sizes.
• Accessories are available for termination of most common cable types.
• Modular wraparound groove plates can be clicked in the UMS (Universal Mounting System) profile. They provide the foundation for mounting combinations of SOSA2 (Splicing Only Sub-Assembly) and/or SASA2 (Splitter Array Sub-Assembly) modules. Typically, Single Circuit or ribbon fiber management is used.
• Kevlar Termination Units (KTU’s) can be mounted in the shelf to provide the necessary strain relief when terminating common pigtail types.
• The shelf is delivered with a metal hangable cover.

16.  Click the groove plates on the aluminum profiles starting from the FAS block; don’t leave any gaps. First position the pins of the groove plate at the back and pull the groove plate to the front until it locks.

17.  Depending on the configuration: fill up the shelf with groove plates, don’t leave any gaps.

18.  If necessary, the groove plates can be removed using 2 flat screwdrivers.

19.  Mount the KTU brackets. Start at the left. Push until they lock.
    Cable to cable

20. In case of a pure cable-cable configuration: no KTU-brackets are placed, the groove plates are not modified, tubes enter at both sides of the FAS block.
    Mounting the trays

21.  Click the trays on the groove plates starting from the fasblock. Preferably mount the trays as you fibre up.
    In case of SC trays (single circuit trays); don’t leave any gaps.

22. In case of SE trays (single element trays), start at the second position and leave 1 space between all the other trays.

23. If necessary, trays can be removed using the fiber guiding pin.

Cable termination

1. Cable termination in the rack
   Cable is already terminated in the rack (or in the side duct of the rack) on the cable termination plate. For the loose tube cable, the tubes are protected from the cable termination plate with the flex tube. For central core cable, fibers are guided into guiding tubes going directly into the shelf.
   Loose tube cable

2. Take the tubes out of the unit. To avoid kinking of the tubes make sure the drawer is closed. To assure correct bend radius: do not reposition the fixed tie wrap.

3. Mounting position: position the toothed lock washer (1) between the tube holder and the side plate.

4.  For back and GR mounting: mount the flex tube holder in the third hole from the front.

5.  In case 2 flex tubes will be used: remove the releasable tie-wrap and mount the plastic stand-off in the first hole from the front.

6. Prepare a piece of flex tube going from the cable termination plate in the rack to the flex tube holder on the shelf.

7. Cable and strength member termination will usually be done in the rack. Terminate the cable in the rack according to Tyco rack installation instruction and local practice. Leave 3.5 m of loose tube measured from the end of the flex tube.

8.  Identify the loose tubes and feed them through the flex tube. Wrap PVC tape around the tubes at the end of the cable to make feeding easier.

9. Bring the flex tube into the flex tube holder.

10. Mount the fixed tie wrap at the position as shown.

11.  In case of front mounting of the shelf: mount the fixed tie wrap as shown.

12. Mark the transportation tube at 30 mm from the end of the flex tube. Mark the loose tube at 20 mm from the end of the flex tube. Note: if the loose tube diameter is < 2,3 mm, the use of the FOPT-CT is not needed. Mark the transportation tubes at the end of the flex tube.

13. Strip the loose tubes from the mark and cut the overlength of the transportation tubes. Clean the fibers very well to make feeding easier.

14.  Select a loose tube and slide a 75mm long FOPT-CT over the transportation tube and loose tube or the transportation tube directly over the loose tube.

15.  Route all tubes underneath the plastic stand-off and close the flex tube holder with the cover.

16. Pull the fibers at the other end of the tubes.

17. If no more loose tubes have to be terminated, cut the unused tubes. Secure the tubes with a tie-wrap.

18.  A second cable can be added using the second flex tube holder.
