How to choose the fiber optic cable correctly

How to choose the fiber optic cable correctly? When outdoor optical cables are directly buried, loose armored optical cables should be selected. For overhead use, loose-buffered cables with a black PE outer jacket with two or more ribs are available.

When choosing optical cables for buildings, you should choose tight-buffered optical cables, and pay attention to their flame-retardant, toxic, and smoke-free characteristics. General ducts or forced ventilation can use flame-retardant and smoke-free (Plenum) or flammable and non-toxic (LSZH), and flame-retardant, non-toxic and smoke-free (standpipe) should be used in exposed environments.

When wiring vertically or horizontally in a building, you can choose tight sleeve optical cables, distribution optical cables or branch optical cables that are commonly used in buildings.

Single-mode and multi-mode optical cables are selected according to network application and optical cable application parameters. Usually indoor and short-distance applications are dominated by multi-mode optical cables, and outdoor and long-distance applications are dominated by single-mode optical cables.

Matters needing attention in optical fiber engineering design

What factors should be paid attention to in system design?

In the application of "fiber to the desktop" in the horizontal subsystem, the relationship with copper cables is complementary and indispensable. Optical fiber has unique advantages such as long transmission distance, stable transmission, no electromagnetic interference, high support bandwidth, and no electromagnetic leakage. These characteristics make optical fiber play an irreplaceable role for copper cables in certain specific environments:

1. When the transmission distance of information points is greater than 100m, if you choose to use copper cables. It is necessary to add repeaters or add network equipment and weak current rooms, thereby increasing costs and hidden dangers, which can be easily solved by using optical fibers.

2.There are a large number of electromagnetic interference sources in specific working environments (such as factories, hospitals, air-conditioning machine rooms, electric machine rooms, etc.), and optical fibers can resist electromagnetic interference and stabilize the operating environment in these environments.
