Outdoor optical cable with strong compression resistance

Technical Field

The utility model relates to an optical cable technical field particularly, relates to an outdoor optical cable that compressive property is strong.

Background

Optical fiber cables (optical fiber cables) are manufactured to meet optical, mechanical, or environmental performance specifications and are telecommunication cable assemblies that utilize one or more optical fibers disposed in a surrounding jacket as the transmission medium and that may be used individually or in groups. 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 existing outdoor optical cable is easy to crack and extrude the fiber core after being pressed, so that the fiber core is broken or the normal work of the outdoor optical cable is influenced.
