4. Installation flow chart
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
- Demount the fixing bolt of insert plate with a special wrench. Put the fixing bolt into the hole with screw thread next to the fixing hole of the insert plate and push the insert plates out with the wrench.
- Use 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 according to 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
- Fiber cable in 60mm length: the distance from seal fitting to fiber cable pressboard
- Fiber cable in 1950mm length: it is used to be winded and spliced after stripping.
- Fiber with protective coat in 350mm 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
Important issues:
- 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 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 prepare work prior to fixing fiber cable.
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 6 inlet/outlet ports. The inlet/outlet ports could be decided according to number and diameters of fiber cables to be actually installed, then the corresponding number of port plugs should be taken out.
5.4.3 This FOSC is suitable for the following diameters of fiber cables respectively:
Port A: suitable for fiber cable with max. diameter ф16mm
Port B: suitable for fiber cable with max. diameter ф13mm
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 seal tape should be used to enlarge the diameter of fiber cable, of which the perimeter could be measured by the corresponding measuring paper (marked with Hole A, Hole B).
5.4.5 The corresponding entry/exit tube cover could be slightly knocked out with screwdriver from inside to outside according to number and diameter of fiber cable required.
5.4.6 Reserve reinforced core in 35mm length and cut off the unnecessary ones.
5.4.7 See Drawing 4.
Important Issues:
- 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.
- Cut off reinforced core with a special cutting plier.
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 small, 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).
5.5.4 See Drawing 5
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.
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 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.
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 installed 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. If not, level it up with seal tape.
5.8.6 Seal the cover of seal fitting
5.8.7 See Drawing 7
5.9 Step Nine – Assemble FOSC housing and fix FOSC
5.9.1 Put the FOSC cover on the FOSC bottom directly.
5.9.2 Insert locating bolt of FOSC and tighten it with the special wrench.
5.9.3 Put the insert plates into the slot (one pair on each side, one piece with a hole with screw thread in the middle, the other with a hole without screw thread in the middle). Tighten bolts of insert plate with the special wrench .
5.9.4 If the FOSC is for aerial application, then put the hanging hook on one side of the closure and then tighten fixing bolts on both sides. Otherwise tighten the 4 fixing bolts at four corners respectively.
5.9.5 See drawing 8
Important issues:
- cleaning the housing and pay attention to the above sequence.
5.10 Step Ten - Fix FOSC .
5.10.1 Fixing the FOSC and tighten bolts in sequence as per drawing 9.
Important issues: Retighten in five minutes
