1.1 Product Description
The FOSC-500-AA is a cold applied re-enterable splice closure for small fiber optic cables. It provides a
mechanical and environmental protection for fiber optic splices and permits easy access by the customer. The
closure is applicable underground, direct buried and aerial. The closure can handle maximum 48 splices and
can be used in-line and in butt configuration. The closure has 4 cable entry ports (two on each side). The cable
sealing is secured by gel-end pieces under compression on both of the closure ends.

depending on the selection and the ordering.
The minimum content will be: the joint body & cover with
• Pre installed - 1 splicing tray (24/48)
- 1 splicing tray cover
- 2 step splice holders
- 2/4 splice holders
- 2 longitudinal rubber seals
- 2 external cable strain relieves
- 1 re-entry label

2.2 Kit contents
3.1.1 Prepare the cable according to the drawing, remove the outer
cable jacket over a length of 1000/1300 mm (40”/50”) and cut the
strength member at 25 mm (1.0”) length.
3 Cable preparation
Cable diameter: minimum 5 mm (0.20”), maximum 15 mm (0.60”).
3.1 Loose tube cable preparation
3.1.2 Remove the loose tubes up to 35/60 mm (1.5”/2.5”) from the
cable cut.
A maximum of 4 loose tubes can be terminated.
Remark: for the 48 splice tray is at the hinge side maximum of 4 loose
tubes possible, on the front side only 2 loose tubes.

3.2 Central core cable preparation
3.2.1 Prepare the cable according to the drawing. Strip the cable
over a length of 1000 mm (40”) for the 24 splice tray, 1300 mm (50”)
for the 48 splice tray and remove the central core up to 35 mm (1.5”)
from the cable cut.
4 Cable installation
4.1 All the fibers should be cleaned and free from cable grease or
dirt.
4.2 Remove the protection foil from the gel sealing blocks of the
closure.
4.4 Remove the cover of the splicing cassette.
A Loose tube cable
4.5 Hold the cable in the correct position and slide the strength
member in the base part of the cable attachment bracket. The loose
tubes should protrude underneath the cable attachment bracket.
Note: the tubes should be oriented in such a way that they are at the
bottom of the cable.
4.6 Secure the cable attachment bracket with a stainless steel cable
clamp to the cable.
4.3 Turn the top part of the outer strain relief clamps 90 degrees to
facilitate the cable fixing on the cable termination point.

4.7 Install the cable with the cable attachment plate in the closure
body on the cable termination point.
4.8 Hold the cable in the correct position and secure the cable
attachment bracket with the stainless steel cable clamp to the cable.
Position the strength members between the plates.
4.9 Install the cable with the cable attachment plate in the closure
body on the cable termination point.

5 Fiber organisation
A 24 splice tray
5.2 Route first the incoming fiber from both sides into the groove
behind the splice holder. Be sure the fibers are beneath all the lips.

5.3 Install the splice protectors in the splice holder and route the
fibers underneath the splice holders and around the tabs (1) in the tray,
first one side and then the other side.
5.4 Splicing cable 1 to 3.
5.5 Route first the incoming fiber from both sides into the groove
behind the splice holder.
5.6 Install the splice protectors in the splice holder (2) and route the
fiber underneath the splice holders and around the tabs (1) in the tray,
fibers at one side of the splice protector you have to make an S to store
them as shown on the picture (3).
5.7 Install the splicing tray cover.

5.11 Install splices in the SMOUV holder (the non-hinged side).
5.9 Use the fiber guiding pin to hold the tray in the open position.
Remark: first use the SMOUV holders at the bottom side of the tray.
When fully populated, use the SMOUV holders at the top side of the
tray.

5.23 Install the splicing tray cover.
6.1.1 Remove 15 mm (0.6”) extra of the outer jacket as shown on the
picture and leave the shield. Install the cable attachment bracket on the
outer jacket. Place the braid (double layer) on top of the shield. Use the
standard steel cable clamp to fix everything on the cable.
6.1.2 Install the continuity braid in the closure as shown on the picture
at the backside of the closure.

6.2 Grounding
6.2.1 Secure the grounding wire with the eyelet to the grounding bolt.
6.2.2 Connect the outer grounding wire onto the outer grounding
feed through of the closure.
7.1 Insert the plugs between the outer strain relief in the unused
cable ports.
7.2 Write down the installation date on the re-entry label in the
cover of the closure.
7.3 Close the cover by closing the latches starting with the middle
latch of the closure.
7.4 Rotate the knob 2-3 times clockwise without pushing on it.
Position the two marking holes of the knob and the closure cover in line
before pushing the locking knob down.
