1 General
1.1 The installation instruction describes the
necessary steps to install the
FOSC-400A4. The used optical fiber cables
may consist of a loose tube, slotted core,
central core or ribbon construction depending
on the type of FOSC kit. Illustrated are the
loose tube construction and fusion splicing
protected by
heat-shrinkable splice protectors.
1.2 The FOSC-400A4 kit is supplied with
one splice tray organizer. One tray (S16)
can accommodate up to 16 fiber splices,
depending the type of tray. A second tray kit
may be used (maximum 2 trays per closure).
1.3 All splice trays accommodate fusion
splice protection types such as Raychem
SMOUV-1120-serie and some types of trays
(S12) most common types of mechanical
splices.
(GTE, FIBRLOK or other similar products).
1.4 FOSC-400A4 closure system has one
oval cable entry port which can handle 2
cables e.g. looped cable and four small
circular ports.
1.5 The seals may only be installed with
hot air (hot-air temperature should be at least
350°C). An open flame is not allowed.
1.6 The FOSC-400A4 can be installed in
direct buried, manholes or aerial locations.
1.7 The kit contents listed in this installation
instruction reflect the standard contents.
Alternative configurations are possible.

4.3 Remove any dirt, mud or other
contaminants from the cable sheath for
approximately 2 meters with a clean cloth.
Take the oval cable seal and slide it over the
cables. The non-coated edge of the sleeve
and the arrows should be pointed to the base
of the closure.
4.2 Install the FOSC in the FOSC-STAND
and open the oval port for cable entry by
cutting the port at the ridge with a hacksaw.
Deburr the inner edge of the port opening
with abrasive strip.
4.1 Loose the clamp.
Push the lever down to release the locking tab.
Open the clamp lever and release the clamp
using the lever legs.
Remove the clamp, dome and sealing ring
and store carefully for later use.
3 General precautions
3.1 Do not use damaged sleeve nor trim
heat-shrinkable sleeve before installation.
3.2 The FOSC-400A4 closures can be
installed at temperatures between -1°C and
+45°C.
3.3 Generators used should have enough
capacity for the hot air gun utilisation.
Optical fiber infrastructure network
elements may contain end of optical fiber
attached to the optical output when the
device is operational. Laser radiation can
seriously damage your eyesight. Please
follow your local safety guidelines.

4.4 Slide the cables through the opened
oval port. Prepare cables as described in
section 5 (cable preparation).
5.2 Order the FOSC-A-SHIELD-CON-KIT if a
shield continuity is required. Cut cable
sheath axially for 25 mm from cable ring cut.
Crimp shield clip on cable sheath with pair
of pliers.
Protect the clip with self adhering tape.
5.3 Cut the loose tube, at a distance of
35 mm from the cable ring cut and remove
and degrease fiber bundle. Select a
transportation tube which fits over the loose
tube. Slip transportation tube over fibers and
the loose tube.
Note: for slotted core cable: use an
appropriate kit which converts the slotted
cable construction into a loose tube
construction.
5.1 Remove the cable sheath (and shield if
present) over a length as required by locally
approved practice (e.g. 1,2 meters). 1.1 m
is the maximum allowed length if the ribbon
(4R4) or high capacity trays (S16) are used.
Clean filling compound from fiber tubes and
cut central strength member at a distance of
75 mm from outer jacket.

6.1 Thoroughly clean oval port and cable
sheath with the cleaning tissue over a
distance of 100 mm from the edge of the
port.
6.2 Abrade oval port and cable sheath
circumferentially on the cleaned area with the
abrasive strip. Remove any abraded material
with a clean cloth.
6.3 Place oval seal over the oval port and
cable. Mark the sleeve length onto the cable.
5.4 Align cable ring cuts with edge of
base.
5.5 Install the screw and washer into the
strength member fixation device. Slide the
cable strength member under the washer and
tighten the screw. Cut the excess length of the
cable strength member.
5.6 If required, connect shield continuity
wire of both cables with shield continuity
clip. Talk pairs, if present, will be connected
together according to the local procedures.

6.7 Shrink down the end of the sleeve on
the cable side. Heat until the sleeve shrinks
down on the cables and take care that the
green thermo-indicating paint is converted to
black. Postheat the clip on both sides till the
adhesive shows a proper flow on the clip
between the two cables.
Wait until the sleeve is cool to the touch
before moving the cables.
6.6 Shrink the oval cable seal on the FOSC-
base side with the recommended hot air gun
device with reflector. Shrink sleeve until the
green thermo-indicating paint is converted to
black. (Make sure the hot-air temperature is at
least 350°C).
(If a FACC-HEAT-GUN-220V is used, set
position on scale 10).
6.4 Match the blue line of the aluminium
cable protection foil with the marks on the
cables. Wrap aluminium cable protection foil
around cable.
6.5 Slide the oval cable seal over the oval
port. Install the branch-off clip. Check that
the heat-shrinkable sleeve butts up against
the FOSC-base and the branch-off clip is
completely inserted. Tape the two cables
together.

Splicing and fiber storage
7.1.3 Position the FOSC-400A4 by the
splicing machine in a convenient location,
and secure the closure.
7.1.4 Slide the heat-shrinkable splice
protection over one fiber and fuse 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.
7.1.1 Each splice tray accommodates 8 fiber
splices maximum and each side of the tray
holds a maximum of 4 big transportation
tubes.
Position the transportation tubes on bottom
tray and align the tubes along the tray. Place
a mark on each tube on tray side at 15 mm
from tray edge.
7.1.2 Carefully cut the transportation tubes at
the mark and secure to splice tray with two tie
wraps. The transportation tube may not be in
contact with fibers stored in the organizer.
7.1.5 After each splice is made, the splice
should be stored in the splice holder. Do not
deform the splice protector during insertion.
The fiber slack should be coiled into the tray.
7 Organization of the fibers
7.1 If a FOSC-A-TRAY-S08-1 is used. Tray
for up to 8 splices
