5. The process of installing FOSC
5.1 Step One - Open the closure
5.1.1 Cleaning the locale and determine where to install the FOSC and then place
fiber cables required.
5.1.2 Check whether the main components and accessories have been well prepared
inside the package.
5.1.3 Open the closure
①Demount the fixing bolt of insert plate with a special wrench. Put out the fixing
bolt，Use the special wrench and stroke on the other side of the insert plate . The
insert plate will be unloading.
2Use the special wrench to demount all the locating bolts on the housing as well as
fixing bolts (it is also possible to install hanging hook depending on the installation
requirement) at four corners, then succeed in opening the closure.
5.1.4 See Drawing 1
Important issues: If the weather condition is not good enough, then a tent must be pitched
for waterproof and dustproof.

5.2 Step Two -Determine length of fiber cable to be fixed and stripped inside FOSC
5.2.1 ①. Fiber cable in 70mm length: the distance from seal fitting to fiber cable pressboard
②. Fiber cable in 2050mm length: it is used to be winded and spliced after stripping.
③. Fiber with protective coat in 450mm length: the distance from the fixing point of
fiber cable to the fixing point of FOST (fiber optic splice tray).
④. Fiber in 1600mm length: after stripping off the protective coat, it is to be winded
inside the FOST after splicing with other fibers
5.2.2 See Drawing 2
Important issues:
1. Reserve enough length of fiber cable to be spliced.
2. Stripping length also could be decided by customer according to installation requirement.

5.3 Step three – Strip off fiber protective coat of fiber cable and fiber
5.3.1 Strip off protective coat of fiber cable from the temp. locating mark with the cutter and the
stripper, please refer to Drawing 2 for stripping length. Stripping length also could be
decided according to installation requirement
5.3.2 See Drawing 3.
Important issues: If it is difficult to pull all the protective coat of fiber cable at one time, strip
it off section by section to avoid fiber breakage.

5.4 Step Four – Separate fiber cores and prepares work prior to fixing fiber.
5.4.1 Wind 2 layers of insulation tape on protective coat of fiber core. Meanwhile, get rid of
the stuffing to separate fiber core and clean them. Form a ring with the diameter
of 100mm or so and fix it on the fiber temporarily by adhesive tape.

5.4.2 This FOSC is provided with six inlet/outlet ports. Number of fiber cables is determined
by the customers according to their actual requirements and the corresponding number
of port plugs should be taken out. The max number of fiber cables to be installed is six.
5.4.3 This FOSC is suitable for the following diameters of fiber cables respectively:
Port A: suitable for fiber cable with max. external diameter ф23mm
Port B: suitable for fiber cable with max. external diameter ф20mm
Port C: suitable for fiber cable with max. external diameter ф16mm
5.4.4 The corresponding inlet/outlet ports are to be selected according to fiber cables
actually installed. When the diameter of fiber cable is smaller than that of the
inlet/outlet port, then the sealing tape should be used to enlarge the external diameter of
fiber cable, of which the perimeter could be measured by measuring paper marked by
Hole A, Hole B, Hole C, coming as accessories.
5.4.5 Reserve reinforced core in 40mm length and cut off the unnecessary ones.
5.4.6 See Drawing 4
Important Issues: 1. Before the seal tape is used for enlarging the fiber cable diameter, it
should be scratched and to be cleaned with abrasive cloth and ethyl
alcohol.
2. Cut off reinforced core with special cutting pliers.

5.5 Step Five - Fix reinforced core and fiber cable
5.5.1 Upon finishing the above steps, then demount port plugs, pressboard and fixing nut of
reinforced core. Make sure to check whether the fiber cable stripped fits in with the
fixing ports or not. If not, the adjustment should be done in time. Otherwise it will affect
installation quality.
5.5.2 Tighten fiber cable pressboard. If the diameter of fiber cable is not long enough, then
enlarge it with insulation tape.
5.5.3 Tighten nut of reinforced core with the special wrench (plastic) and then retighten it with
the metal wrench.(the metal wrench should be provided by operator).

5.6 Step six - Splice fibers
5.6.1 Follow user manual of fusion splicing machine to splice fiber cores.
Important issue: pay attention to the twist and bend of fiber.
5.7 Step Seven -Install heat shrinkable protective sleeve and house fibers
5.7.1 When having completed splicing the fibers, the first fiber ring should be housed
on the farthest side of FOST, the remaining fiber should be winded, forming a ring
with diameter not less than 80mm. then put it into FOST (Fiber Optic Splice Tray)
together with heat shrinkable sleeve for splice protection.
( Firstly fix heat shrinkable protective sleeve into the slot, then enlarge the diameter of
fiber ring properly.)

5.8 Step eight - Check up comprehensively
To ensure the technical requirements, the following instructions must be followed:
5.8.1 The fibers in the FOST are spliced and installed orderly. The curved diameter
of fiber meets with the technical requirements.
5.8.2 The internal tighteners are tightened.
5.8.3 The inlet/outlet ports without fiber cables must be blocked up with the port plugs.
5.8.4 Control the amount of seal tape within a proper range.
5.8.5 Seal fitting is installed neatly and smoothly.
5.8.6 Seal the cover of seal fitting
