9 .5 Ground Cable
Attach the ring terminal on the ground wire to the ground stud
inside the cabinet (Figure 23). Add a washer and a nut and
tighten to a torque value of 23 in-lb.
10 . Splicing
Before splicing fibers, determine the fiber routing
configuration you will use in your splicing application. Buffer
tubes may enter the splice tray and have all fibers in the
buffer tube spliced at that time or stored in the tray for
splicing later. It is also possible to splice one fiber from a
buffer tube and express the remaining fibers out of the splice tray.
Key Notes for Splicing
•
Rotational access is provided to the splice trays within the splice housing.
•
Maximum of seven splice trays can be accommodated within the splice housing (one
reserved for Feeder splicing and six for Distribution splicing). Each splice tray holds six
heatshrink mass fusion splices for a maximum of 72 splices per tray.
•
Feeder splicing occurs in the bottom splice tray in the splice housing with Distribution
splicing in subsequent trays above.
•
Two sub-units (jacketed or braided tubing) with three 12-fiber ribbons per sub-unit can be
strain-relieved to each feeder splice tray.
•
Two sub-unit pigtails from the back of the Input Fiber Field panel to the feeder splice tray are
pre-routed at the factory and stored for splicing.
•
Two sub-units (jacketed or braided tubing) with three 12-fiber ribbons per sub-unit strain-
relieved to each distribution splice tray.
•
Two sub-unit pigtails from the back of the Distribution panel to the distribution splice tray are
pre-routed at the factory and stored for splicing.
Feeder cable (F1) will
route to the bottom splice
tray and the Distribution
cable (F2) will route to the
subsequent trays above
in preparation for splicing
(Figure 24). Pigtails from
the Distribution panel
and/or splitter inputs
have been pre-routed
and stored in the splice
housing. To gain access
to the bottom splice tray,
loosen the hook-and-loop
strap and remove the top
trays.
