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.

2.4.5 FOSC-WORK-STAND

FOSC holder device

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 Cable installation in oval

outlet

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.

5 Cable preparation

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.

for up to 8 splices
