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).
5.5.4 See Drawing 5
