Patch application
There are 2 sizes of patch trays available:
Information about the amount and the type of adapters
compatible with this tray can be retrieved in the eCatalog.
Both trays have at one side of the tray a slit to route the
patch cord from the front side of the tray to the back side.
If present, the two or three splice trays must be installed in
the bottom positions of the tower. On top of these trays,
the patch trays are installed. Patch trays should be installed
above the lips of the fiber guidance channel therefor the
patch trays can only be installed starting from a certain
position on the tower:
- position 4 for the C6 enclosure and;
- position 3 for B6/C6H enclosure.
Between two patch trays one or two hinge positions must
remain unused; see table below:

Push the tray hinge of the patch tray into the
snap features on the tower. Start with position 4 for the C6H
enclosure and with position 3 for the C6H and B6 enclosures.

13.2. Routing on the tray
Select the groove on the tower that routes the fiber to the
tray. The fiber continues in the groove of the tray. Fibers
entering the tray from the opposite sides cross each others in
the middle of the tray (called FAS).
Fibers can be stored around the island present on each tray.
(See dotted black lines on image below.) On some trays,
there are pass through grooves available between and under
the splice protector holders. These can be used the store
more or longer length of fiber.
Splice per standard practice and store the splice protector in
the splice protector holder.
Note
: the FAS on the tray can be used to make crossings on
the tray; if the fibers need to be spliced enters the tray from
the same side, one fiber can make a S-shaped U-turn on the
tray using the openings in the island (see blue dotted line on
the image above).
Note:
When storing (over length) fibers, observe the
following general rules:
1. The fibers may not be routed too tight around the island.
2. Make sure all fibers are properly positioned under the lips.
