4. Installation flow chart
The process of installing FOSC
Step One - Open the closure
Cleaning the locale and determine where to install the FOSC and then place
fiber cables required.
Check whether the main components and accessories have been well prepared
inside the package.
Open the closure by demounting the fixing bolt (5 pieces) of the housing, then succeed
in opening the closure.
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 . Fiber cable in 70mm length: the distance from seal fitting to fiber cable pressboard
. Fiber cable in 1720mm length: it is used to be winded and spliced after stripping.
. Fiber with protective coat in 120mm length: the distance from the fixing point of fiber cable to the fixing point of FOST (fiber optic splice tray).
. 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
Reserve enough length of fiber cable to be spliced.
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 strip off 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 prepare work prior to fixing fiber.
Wind 2 layers of insulation tape on protective coat of fiber core. Meanwhile, get rid of
the stuffing to separate fiber and clean them. Form a ring with the diameter of 100mm
or so and fix it on the fiber temporarily by adhesive tape.
This FOSC is provided with 2 inlet/outlet tubes, each of which suit for 1 piece of fiber
cable with max. diameter ф14mm or 2 pieces of fiber cable with max. diameter
ф11mm. The corresponding port plug could be taken out according to number of fiber
cable actually required. The max. number of fiber cables with diameter ф11mm to be installed is 4.
5.4.3 Reserve reinforced core in 30mm length and cut off the unnecessary ones.
5.4.4 See Drawing 4
Important Issues: Cut off reinforced core with a special cutting plier.
5.5 Step Five - Fix reinforced core and fiber cable
5.5.1 After deciding number of fiber cable inlet/outlet, demount the nut and gasket of the
corresponding inlet/outlet tube. Insert them into fiber cables in sequence, which are to be
inserted into inlet/outlet tube then.
Fix fiber cable to fixing device of fiber cable (while diameter of fiber cable is small,
enlarge the diameter with insulation tape), then fix the reinforced core to the fixing device
of the reinforced core.
Push the first gasket into inlet/outlet tube, then enlarge the diameter of fiber cable with
seal tape (to fit in with internal diameter of inlet/outlet tube). Then push the second
gasket and the seal tape into inlet/outlet tube, which is to be tightened with octagonal
See Drawing 5
Important issues: before the seal tape is used for enlarging the diameter of fiber cable, it should be scratched and to be cleaned with abrasive cloth and ethyl alcohol.
5.6 Step Six - Splice fibers
5.6.1 Follow user manual of fusion splicing machine to splice fiber.
Important issue: pay attention to the twist and bend of fiber.
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 protective sleeve.
( Firstly fix heat shrinkable protective sleeve into the slot, then enlarge the diameter of
fiber ring properly.)
5.7.2 see Drawing 6
Important issue: pay attention to the twist and bend of fiber.
Step Eight - Check up comprehensively
To ensure the technical requirements, the following instructions must be followed:
Fibers with protective coat are fixed with nylon tie at the entrance of FOST.
Grommet should be pressed from inside to outside in order to properly install FOST.
Check whether the internal tighteners and bolt of reinforced core is well tightened
Check whether integrated seal fitting is installed neatly and smoothly without any breakage. If not, level it up with seal tape.
See Drawing 7.
Important issues: If any problems occur, they should be solved right away.
5.9 Step Nine - Install FOSC housing
5.9.1 Tighten fixing bolts of the housing
5.9.2 Tighten octagonal nuts
5.9.3 Either wall mounting or aerial mounting is possible according to the actual installation
Wall mounting application: fixing device for wall mounting should be installed at the
bottom of FOSC, which is to be fixed with plastic intumescent screw and bolts.
Aerial mounting application: fix hanging hook on the wall.
5.9.3. See drawing 8
Important issues: 1. Clean the housing
2. Tighten bolts in sequence.
