The physical structure of indoor optical cables

Indoor optical cable is a cable formed by a certain process of optical fiber (optical transmission carrier).

Indoor optical cables are mainly composed of optical fibers (glass fibers as thin as hair), plastic protective sleeves, and plastic sheaths. There are no metals such as gold, silver, copper, or aluminum inside the cable, and it generally has no recycling value.

Indoor optical cable is a communication line that uses a certain number of optical fibers to form a cable core in a certain way, wrapped with a sheath, and some even wrapped with an outer protective layer, to achieve optical signal transmission.
