Cable selection rule

Selection of cable should pay attention to what? In addition to the selection of fiber optic cable fiber count and fiber according to types of thought, but also to choose based on the use of fiber optic cable outer sheath.
The following are selected cable law, we should note these points:
1 outdoor fiber optic cable buried the appropriate selection of Kay-like fiber. Overhead, can be selected with more than two root ribs and the black plastic outer sheath of the cable.
(2) buildings used in the selection of fiber optic cable should pay attention to the flame, smoke and toxicity characteristics. Generally in the pipe and forced ventilation can choose the type of fire, but smoke, exposure to the environment should be used flame retardant, smoke-free and non-toxic type.
3 vertical wiring inside the building, you can choose Layer Stranding Cable (Distribution Cables); horizontal cabling type, can be used to branch cable (Breakout Cables).
4 transmission distance in less than 2Km, the choice of multi-mode light, more than 2Km relay or use single-mode fiber optic cable can be used. These are put aside their own fiber optic cable price and quality factors, one should note from the application to consider several issues. Implementation need to be flexible. In fact, complex and diverse routing environment, all kinds of problems may arise, which we need in the planning and construction in strict accordance with wiring standards implementation, flexible analysis of a problem, I believe the problem will be resolved.
