11. Splicing

11.1

Work on one splice tray at a time. Follow

the instructions provided with the splice trays.

a) Position the splice tray in the location it will

be secured to the holder.

b) Route two complete loops of buffer tube(s)

in a counterclockwise direction around the
radius guides. The radius guides are
designed with three sections. Begin routing
from the back section and work your way
forward with each loop in a different
section.

c) Place the buffer tube(s) where they will lie

after installation and mark the cable where
it will enter the splice tray 2 cm (

3

/

4

 inch)

past the corner of the tray (Figure 15). (This
is where the buffer tube will be removed.)

d) Loop the pigtail fiber from the connector

panel around the radius guides as shown in
Figure 16 and mark the jacket the same way
you did for the buffer tube(s). Remove the
cable jacket from the pigtail.

Figure 16

e) Refer to the instructions provided with the

splice trays to determine the appropriate
length of fiber required in the tray. Measure
from the first mark towards the end of the
cable and mark the cable. (This is the fiber
that will be routed inside the splice tray.)

f) Trim the excess buffer tube beyond the

second mark.

g) Remove the splice tray and the coiled buffer

tubes.

h) Strip the buffer tube from the fibers from

the mark you made in the previous step c).
Clean the fibers that will be inside the tray
according to the cable manufacturer’s
instructions.

11.2

Bring both pigtails and buffered fibers to a

convenient splicing area - one pair at a time.
Secure these fibers to the splice tray according
to the instruction supplied with the splice tray.

IMPORTANT:

 When securing 900

µ

m fiber to

the splice tray, 1.5 inch of vinyl tape around the
sheath as protection for the 900 

µ

m fiber is

recommended. Feed a cable tie through the strain-
relief holes in the corner of the tray. Carefully
tighten the cable tie around the tape-wrapped
portion of the fibers to secure the fibers to the tray.

11.3

Splice fibers as described in instructions

for the splicing method you are using.
