1. The protective structure of the outer layer of the optical fiber can prevent damage to the optical fiber from the surrounding environment. Optical cable includes optical fiber, buffer layer and coating. Optical fiber is similar to coaxial cable, except that there is no mesh shield. In the center is the glass core through which light propagates.
Optical fibers are usually bundled and protected by a casing. The fiber core is usually a double-layer concentric cylinder with a small cross-sectional area made of quartz glass. It is brittle and easy to break, so an external protective layer is required. So their difference lies in this.
2. Optical fiber cable: It is mainly composed of optical fiber (glass filaments as thin as hair), plastic protective sleeve and plastic sheath. There is no metal such as gold, silver, copper and aluminum in the optical cable, and generally has no recycling value.
An optical cable is a communication line in which a certain number of optical fibers compose a cable core in a certain manner, and are covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission. Namely: Optical cable is a cable formed by optical fiber (optical transmission carrier) through a certain process.
