4. 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

  • Demount hoop fixing bolt and pull hoop locking system out, then proceed in

demounting the hoop.

  • Pull the FOSC cover upwards out, installation could begin.

See Drawing 1

Important issues: If the weather condition is not good enough, then a tent must

be pitched for waterproof and dustproof.


Step Two -Determine length of fiber cable to be fixed and stripped inside FOSC

4.2.1 ①. Fiber cable in 120mm length: the distance from small gasket ring to fiber cable

pressboard

②. Fiber cable in 1740mm length: it is used to be winded and spliced after stripping.

③. Fiber with protective coat in 140mm 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

4.2.2 See Drawing 2

Important issues: 1. Reserve enough length of fiber cable to be spliced.

2. Stripping length also could be decided by customers according to

installation requirement
