1.1 Installation Instruction description
Theinstallation instruction describes the necessary steps to install the SCIL-B.
The installation instruction illustrates the use on loose tube cables. If other cable types (slotted
core or central core) are used, supplementary installation steps have to be made. Contact the
local agent to get the relevant accessories and instructions.
1.2 Product description
TheSCIL-B splice closure in-line is a gel-sealed fiber optic splice closure designed for cable joint
applications in the telecom outside plant network. Theclosure has maximum splicingcapacity of
192 splicesand is suitablefor deploymentin aerial,undergroundor directburied environments.
Sealing is achieved via built-in gel technology, resulting in extremely convenient re-entry and re-
sealing. Theclosure has four cable ports, two onboth sides.

4 Cable Installation (Floating cable bracket)
4.1 Looped Cable
4.1.1 Make a window cut of 2600mm
4.1.2 Cut the loose tube of the to be spliced fibers in the
middle (1300mm) and continue the installation on 4.3
4.2 Drop cables
4.2.1 Remove the cable sheath over 1300 mm.

3
4.3 Cut the strength member on both sides at a distance
of 50 mm from the cable window cut.
4.4 Install the strength member into the holding lug and
secure the lug to the cable attachment bracket with the bolt.
4.5 Terminate and secure the cable attachment bracket to
the cable sheath with the cable hose clamp.
4.6 Assure that the lug lip, the securing bolt and the hose
clamp head are positioned downwards to the bottom of the
closure. Protect the cable hose clamp and the termination with
some layers of PVC tape.
4.7 Clean the cable sheath with the cleaning tissue
4.8 Select the appropriate blocking rings according to the
cable outer diameter. It is preferred that the blocking ring is
slightly larger than the cable diameter.
4.9 Cut the selected rings on the mark.
4.10 Insert the cable attachment bracket into the bracket
holding slot as shown.

4
4.11 Mark the cable where blocking rings will be installed as
shown. Install the rings over the cable with the slit positioned
under the cable.
4.12 Wrap gel strip around cable between the two blocking
rings. Press first part of the strip onto the cable to ensure the
strip sticks to the cable firmly. Make sure the strip is wrapped
smoothly without twisting between layers.
4.13 Verify with a flat tool. Continue wrapping the strip
smoothly till the area between the two blocking rings is filled with
gel strip.
4.14 At the cable port where cable will be installed, install
two pieces of black tie wraps.
4.15 Position the cable with the pre-installed cable sealing
block into the cable port and insert the cable attachment bracket
into the holding slot as picture shown.
4.16 Secure the cable with the black tie wraps.
4.17 Apply unused cable ports with cable plugs. Wrap cable
plug with gel strip in the same way as wrapping cable.
50mm

5
4.18 Install a cable plug (hole towards outside) in all unused
closure cable ports.
5 Cable Installation (Fixed Cable Bracket)
5.1 Repeat the step 4.1 – 4.2
5.2 Cut the strength member on both sides at a distance
of 30 mm from the cable window cut.
5.3 Mark at 55mm and 90mm from the cable jacket end.
5.4 Repeat installation step 4.8 -4.9. Install 2pc ring trees
over the cable.
5.5 Wrap the cable with gel strip. Verify with a flat tool.
Continue wrapping the strip smoothly till the area between the
two blocking rings is filled with gel strip.
5.6 Remove the block when cable OD>16mm.
5.7 Tighten the screw to secure the strength member.
30mm

6
5.8 Make sure the ring tree in the slot and secure the
cable.
5.9 Secure the cable with UV-resistant tie wrap
5.9.1 Apply unused cable ports with cable plugs. Wrap cable
plug with gel strip in the same way as wrapping cable.
5.9.2 Install a cable plug (hole towards outside) in all unused
closure cable ports.
6 Fiber preparation
6.1 When using Tray 24
6.1.1 In case of a looped cable, coil the loops and store
them in the space in front of the tower of the closure (loops can
be stored around the tower as well).
6.1.2 Remove the loose tubes of the to be spliced fiber
bundles up to 150 mm from the cable jacket (see drawing 5.1.4).
6.1.3 Degrease the fiber bundle. Slide the transportation
tubes over the fibers up to 50 mm from the cable jacket end (see
drawing 6.1.4).
6.1.4 Sketch for tube installation.

7
6.1.5 Route the transportation tubes to the tray entrance.
Always route the tubes around the tray tower before entering the
tray.
6.1.6 Secure the transportation tube at the splice tray
entrance with two tie-wraps.
6.2 When using Tray 48
6.2.1 In case of a looped cable, Coil the loops and store
them under the tray, and use tie wraps to tie up the bundle。
6.2.2 Remove the loose tubes up to 100mm from the cable
jacket end。
6.2.3 Degrease the fiber bundle and slide the transportation
tubes over the fibers with overlap 100mm
6.2.4 Route the transportation tubes to the tray entrance as
shown.
6.2.5 Secure the transportation tube at the tray entrance
with two tie wraps
100 mm
50 mm

8
6.2.6 Store fibers on the tray properly.
6.2.7 Remove/Install tray 48 as following shows
6.3 When using Tray 12 (Thin tray)
6.3.1 Same as 6.1.1
6.3.2 Same as 6.1.2
6.3.3 Degrease the fiber bundle. Slide the thicker
transportation tubes over the fibers up to 50 mm from the cable
jacket end and then insert the thinner transportation tube into the
thicker one with overlap 30mm (see drawing 6.2.4).
6.3.4 Sketch for tube installation.
6.3.5 Same as 6.1.5
6.3.6 Insert the thinner transportation tube to the splice tray
entrance directly.

7.1
Splicing and fiber storage
Position the SCIL-B close to the splicing machine
in a convenient location and secure the closure.
7.2 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 an appropriate
heating source. Allow the splice protection to cool down to
ambient temperature.
7.3 After each splice is made, the splice should be stored
in the splice holder in the appropriate position. Do not deform the
splice protector during insertion.
7.4 Incoming fibers should be routed first behind the splice
holder before the over-length is coiled into the tray. Route the
fibers through the cross of the tray as shown.
30mm Thinner tube

7.5 In case of two or more trays, use tray wedge to keep
the upper trays in upward position during installation on lower
tray.
7.6 After use, the tray wedge can be stored on the tower
underneath the installed trays.
7.7 Put on butterfly tabs and tray lid to secure the fiber if
using 48 trays
7.8 Secure the trays by the Velcro.
8 Closing of the closure
8.1 Close the cover by closing the latches in the proper
sequence shown in 7.2.

9 Field mounting of the closure
9.1 Termination on aerial cables. Use the special designed
bracket to secure the closure onto the supporting wire of the
aerial cable. Install the two pieces bracket facing with bowing
outwards to interlock the aerial cable.
9.2 Termination in manholes. Secure the closure to the
manhole frames with bolts in the provided positions on the
bottom part of the closure.
10 Re-opening
