Description

technical field [0001] The invention relates to an optical cable structure, in particular to a rectangular optical fiber core optical cable. Background technique [0002] Optical cable is a light transmission tool that achieves the principle of total reflection of light in fibers made of glass or plastic. An optical cable is a communication line in which a certain number of optical fibers 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. In the prior art, the structure of the optical cable includes an internal optical fiber module and an external protective layer structure. The optical fiber module is formed by a circular array of multiple optical fibers, and there is no filling material between the optical fibers. , Arbitrarily make the internal optical fibers squeeze each other, which is very harmful to the optical fiber. At the same time, this kind of optical fiber ...

In the prior art, the structure of the optical cable includes an internal optical fiber module and an external protective layer structure. The optical fiber module is formed by a circular array of multiple optical fibers, and there is no filling material between the optical fibers. , arbitrarily make the internal optical fibers squeeze each other, which is very harmful to the optical fiber. At the same time, this type of optical fiber is easy to cause the optical cable to rotate around its own axis during the laying of long lines, which will aggravate the mutual extrusion between the optical fibers.
