6.0 Cable Routing
Note: If this is a new closure, remove any installed trays that
might make fiber routing easier. Install trays as you go. Refer
to section 4.0 for cable preparation.
Go to:
6.1 for Loose Buffer Tube Cable
6.2 for Central Core Tube Cable
6.1 Loose Buffer Tube Cable Installation
1. Review IMPORTANT RULES from pg. 4.
Note: If the LBT cable contains the older style stiff LBT’s, it will
be necessary to ring cut the LBT 1-1/2” from the ring cut and
install transportation tubes over the LBT for routing.
2. Route loose buffer tubes (LBT) either to the basket for slack
storage or to the tray for splicing. LBT’s can be routed directly from
the port to the tray or from the basket to the tray(s).
Note: If installing a midspan and need to splice only part of the
fibers in a loose buffer tube (LBT), go to step 6.
3. Mark the LBT and ring cut as shown (Fig. 11). Remove LBT and
clean fibers.
4. Secure the LBT to the tray with tie-wraps.
Note: Felt wrap can be installed onto LBT’s to provide better
resistance to pull-out prior to tie-wrapping tubes to the tray.
5. Splice and organize fibers on the tray. Once all splicing is
complete, go to section 7.0
6. Route the designated uncut LBT to the tray as shown below and
mark tubes. The LBT will be routed and secured on both right and
left sides of the tray. Mark the tube as shown. (Fig. 11).
7. Shave the LBT back to each marks on the tube and remove
section of LBT.
8. Secure each end of the LBT to the tray and clean the fibers.
9. Route drop fibers to be spliced to the same tray. Secure tube(s)
with tie-wraps.
10. Splice and store the designated fibers into the tray first .
11. Store the uncut fibers last. This will allow easy access to the
uncut fiber if they need to be spliced at a later time. Once all
splicing is complete, go to section 7.0
