Since the 21 st century, the telecommunications industry has grown dramatically and optical cables, which are manufactured to meet optical, mechanical or environmental performance specifications, are widely used in a variety of applications, and utilize one or more optical fibers disposed in a covering jacket as the transmission medium and may be used individually or in groups as a telecommunications cable assembly. The optical cable is mainly composed of optical fibers (thin glass filaments like hair), a plastic protective sleeve and a plastic sheath, and metals such as gold, silver, copper and aluminum are not contained in the optical cable, so that the optical cable generally has no recycling value. The optical cable is a communication line which is formed by a certain number of optical fibers into a cable core in a certain mode, is externally coated with a sheath, and is also coated with an outer protective layer for realizing optical signal transmission. Namely: a cable formed by subjecting an optical fiber (optical transmission carrier) to a certain process. The basic structure of the optical cable generally comprises a cable core, a reinforcing steel wire, a filler, a sheath and other parts, and further comprises a waterproof layer, a buffer layer, an insulated metal wire and other components according to requirements.

The optical cable is noticed that generally bending is avoided too much in the use process, because the optical fiber inside the optical cable is realized through the total reflection principle of light, the light ray is injected perpendicular to the end face of the optical fiber, and when coinciding with the axis of the optical fiber, the light ray is transmitted forwards along the axis, the bending degree is too great, and partial light ray can not normally pass through, so that the light power is reduced, further the signal loss is caused, when the bending amplitude is too great, even the light transmission is damaged, the communication fault is caused, and huge loss can be caused.

Especially, once an optical fiber is bent too much, an important communication part in a communication project, such as a data transmission node, interferes with data transmission or has a very large loss of interrupting data transmission, so that the optical fiber of the part should be protected mainly to prevent the over-bending phenomenon, then in the prior art, a foreign object is mostly adopted for protection, but the bending phenomenon in the laying process is still difficult to avoid, particularly, the micro-bending which is not easy to be perceived by naked eyes, and the optical fiber is easy to be damaged.
