About fiber optic cables
A cable formed by a certain process of optical fiber is called an optical cable. The basic structure of optical cable is generally composed of cable core, reinforcing steel wire, filler and sheath, etc. In addition, there are waterproof layer, buffer layer, insulated metal wire and other components as needed.
Layer twisted structure optical cable
It is formed by twisting the loosely molded optical fiber around the reinforcing core. The layered structure optical cable is similar to the traditional cable structure, so it is also called the classical optical cable. It is characterized by simple cable core manufacturing equipment, mature technology, good tensile strength and improved temperature characteristics.
Skeleton structure optical cable
The skeleton structure optical cable is formed by placing the tight-buffered optical fiber or the once-coated optical fiber into the spiral plastic skeleton groove around the reinforcing core. This structure has good lateral pressure resistance and is beneficial to the protection of the optical fiber.
Bundled tube structure optical cable
The primary coated optical fiber or optical fiber bundle is put into a large ferrule, and the reinforcing core is arranged around the ferrule. This structure is lighter in weight.
Stranded Ribbon Cable
Put the ribbon fiber unit into the groove or loose tube to form a skeleton or layered structure. It is conducive to the use of high-density access network optical cables.
Single core structure optical cable
Referred to as single-core flexible optical cable for short, the optical cable of this structure is mainly used for intra-office (or station) or for making instrument test cords and special optical cables for special communication places and optical fibers for making single-core flexible optical cables.
Special structure optical cable
Optical cables with special structures, mainly submarine optical cables and metal-free optical cables.
(1) Submarine optical cable
(2) Metal-free optical cable
Metal-free optical cable means that the optical cable is all plastic except for the optical fiber and insulating medium (including reinforcing members and sheaths), which is suitable for strong electrical occasions, such as power stations, electrified railways and strong electromagnetic interference areas.
