150 cm free fibre
ca. 11 cm tube
6C. Fibre tubes, in corrugated tubes
6.7 Preparation of cable when using corrugated tube
Strip the cable 161 cm + the length of the corrugated tube and prepare as
shown in drawing 6.7.
If rubber tubes, do not tighten the tie
-
wraps too hard.
The tubes may in this case be 19 cm outside the corrugated tube and end as in
drawing 6.8.
Protect the fibre
-
tubes using foam tape and fasten the tubes to the two
foremost punched out mounts in the drawer using tie
-
wraps. The foam tape
will also protect the tubes from slipping. The corrugated tube is fastened with
tie
-
wraps to the holes in the back
-
wall as shown in drawing 6.8.
Then follow the instructions in chapter 6A figure 6.3, or chapter 6B figure 6.5
depending on number of fibres.
6.8 Fastening of the corrugated tube.
Prepare the cable(s) as shown in drawing 6.4.
It may be beneficial to await
cutting the tubes until the respective fibres are to be used.
Loosen the snap
-
latches and pull out the drawer.
Up to 96 fibres (LC): Insert the adapters from the outside with the key to
the right.
72 fibres (SC)/144 fibres (LC): Insert two
adapters in each hole.
Both adapter types are inserted with the keys away from each
other (one left and one right) as shown.
Mount two splice holders in the two mid holes (one for each holder) as shown
in drawing 6.5. They are fixed with rivets through one of the
“
nut holes
”
at
the end of the holder (shown as black dots).
Fasten the cable to the two foremost punched out mounts and to the lower
hole in the back
-
wall of the drawer using tie
-
wraps. Any excess cable must be
handled outside of the panel
The adapter plate may be lifted up and turned to give easier access to the
adapters on the inside. See ch. 4.3. Clean the adapters.
IMPORTANT:
If the pigtails are more than 1.2 m long, they should be cut to
this length.
Attach splice protectors and splice the first 4 fibres, put the fibres in the fibre
guide crosses as shown in drawing 6.6 and place the splice protectors in the
splice holders. Clean the connectors and insert them in the adapters. Follow
the colour coding.
Continue with 4 and 4 fibres until the first splice holder is full. Put the second
splice holder on top of the first (clipped on, turned 180° compared to the
first). Splice and place the next 12 fibres, fibre 13 to 24 in track 1 to 12 of this
splice holder.
Continue in the same way until the left stack of the splice holder have
covered half of the total fibre count. Then continue with the right stack.
Close the fibre guides
(see picture 3.2.1).
