Optical signals can propagate and advance in the fiber core, so they are mainly used as the medium of communication transmission. However, because the optical fiber itself is very fragile, it cannot be directly applied.

Since the optical fiber itself is very fragile and cannot be directly connected to the wiring system, the optical fiber is often protected by a casing with a reinforcement in the middle. This is the optical fiber cable we usually hear and see. According to the use environment, the optical fiber cable is generally divided into outdoor and indoor. The following editor will explain the difference between outdoor optical fiber cable and indoor optical fiber cable.

Indoor fiber optic cable

There is no metal in the indoor optical fiber cable, and generally has no recycling value. It is a kind of communication line that uses a certain number of optical fibers to form a cable core in a certain way, and is covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission. Indoor optical fiber cable have low tensile strength and poor protective layers, but are also lighter and more economical. Indoor optical fiber cable are mainly used for wiring in buildings and connections between network devices.

Outdoor fiber optic cable

The outdoor optical fiber cable is similar to the indoor optical cable in terms of structure and composition, but because of its particularity, the use environment is different. The outdoor optical fiber cable has a higher tensile strength, a thicker protective layer, and is usually armored (that is, wrapped in a metal skin). ). Outdoor optical cables are mainly used for interconnection between buildings and between remote networks.
