1 Introduction
The FOSC-450 is an environmentally sealed enclosure for the fiber management system that provides the function
of splicing in the external network.
The FOSC-450 has provision for all cable terminations and sealing requirements.
The closure is a single ended design made of a thermoplastic material. The base and dome are sealed with a
clamp, pre installed Gel-O-ring system. For cable sealing, a wrap-around block with 6 ports is used that contains
a pre-installed gel profile. One can terminate 6 cables, with a diameter of minimum 9 mm and maximum 25 mm.
It can be opened and closed repeatedly without the need to replace the gel.

fibers to the tray.
4.4.10 Install the spiral tubes of 20 cm on the cable. Fix the spiral tube
on the basket in the middle with tie-wraps and route the bare fiber in the
basket, wrap some foam around the spiral tube for good fixation with
the tie-wrap.

the unused ports.
Remark: when installing the plugs be sure not to bend the crowns in the
gel block.

6.1.1 Direct from the cable to the tray. Strip the loose tube at 55 mm
from the outer jacket.
6 Fiber routing
6.1 Fiber routing to the tray
Loose tube (looped cable and track joint)
6.1.3 For proper routing to the individual trays.
6.1.2 Select a transportation tube that fits over the loose tube. Slide
the transportation tube over the fibers and the loose tube. Place the
transportation tube on the tray, mark at 15 mm of the tray edge and
cut. 6.1.4 Cable installed with single bracklet.

11
6.1.5 From the basket to the trays with the transportation tube. Routing
always from one side to the other side, see picture.
6.2 Fiber routing on the tray
6.2.1 Splicing
For heat shrinkable splice protectors:
• slide the heat-shrinkable splice protector over one fiber.
• fuse the fibers according to local recommendations and procedures.
• after the fusion splice is made, install the heat shrinkable splice
protection (e.g. smouv) with appropriate heating source.
• allow the splice protection to cool down to ambient temperature.
For ANT splice protectors:
• fuse the fibers according to local recommendations and procedures.
• after the fusion splice is made, install the ANT splice protector with
appropriate tool.
6.2.2 Storage
After each splice is made, the splice should be stored in the splice
holder. Do not deform the splice during insertion. The fiber slack should
be coiled into the tray. Follow the routing as shown.
6.2.3 If a tray for up to 16 heat shrinkable fusion splice protectors
is used
• The tray organizer has 6 locations to store splice protectors.
Each location can hold maximum 4 fusion splice protectors of type
smouv-1120-02 (length 45 mm, installed outer diameter is 2,4 mm)
or equivalent.
• After each splice is made, the splice should be stored as
indicated on the drawing. First protector in position 1, the second
in position 2. Continue for other fibers. Fiber nr 5 will be in position
1 of next location.
• If splice protectors are stored on the side with the 4 locations,
the fibers from the locations on the outside are first guided through
the passage between the locations and then coiled into the tray.
6.1.4 First to the basket (see 5.1.11).
Central core

12
6.2.5 If a tray for up to 16 ant splice protectors is used
(FOSC-A-TRAY-A16)
• The tray organizer has 4 locations to store protectors. Each
location can hold maximum 4 fusion splice protectors of type ANT.
• Coil the excess length of fiber each time you have positioned the
splice protector.
6.2.6 If a tray for up to 24 ant splice protectors is used
( FOSC-A-TRAY-A24).
• The tray organizer has 6 locations to store splice protectors. Each
location can hold maximum 4 fusion splice protectors of type ANT.
• After each splice is made, the splice should be stored in the splice
holder.
• If splice protectors are positioned on the side with the 4 locations,
The fibers from the locations on the outside are first routed through
the passage between the locations and then coiled into the tray.
6.2.4 If a tray for up to 24 heat-shrinkable fusion splice protectors is
used ( FOSC-A-TRAY-S24)
• The tray organizer has 6 locations to store splice protectors. Each
location can hold maximum 4 fusion splice protectors of type smouv-
1120-02 (length 45 mm, installed outer diameter is
2,4 mm) or equivalent.
• After each splice is made, the splice should be stored as indicated
on the drawing. First protector in position 1, the second in
position 2. Continue for other fibers. Fiber nr. 5 will be in position
1 of next location.
• If splice protectors are stored on the side with the 4 locations, the
fibers from the locations on the outside are first guided through the
passage between the locations and then coiled into the tray.

7.2 Protect with tape.
6.2.7 Follow the arrows on the trays. For this tray smouv-1120-02
and SMOUV-1120-02 can be used for splice protection
(FOSC-ACC-A-TRAY-12). 7.1 Install the grounding wire as shown on the picture.

8.1 Place the hook and loop fastener over the trays and basket,
place the hook and loop fastener eye on top of the trays.
8.2 Slide the base back over the Gel block and insert the frame
into the base (check proper position).
8.3 Tighten the trigger until it butts. If necessary, use wrench
(n° 12) to tighten the trigger.
8.4 Place the dome. At the end turn the dome until it fits. Use the
clamp to seal dome and base.
9 Important steps
• Before starting, slide the base over the cables.
• Routing from the basket to the trays, always from one side to the
other side.
• Avoid in all cases crossing of fibers and loose tubes.
• Replace the silica gel after each re-entry.
• Do not mount the closure with the base pointing up.
