Description

Technical Field

[0001] The utility model relates to the technical field of optical cables, in particular to the technical field of extrusion-resistant optical cables. Background Art

[0002] Optical fiber cables are manufactured to meet optical, mechanical, and environmental performance specifications. They utilize one or more optical fibers enclosed in a sheath as the transmission medium and can be used individually or in groups. Optical fiber cables primarily consist of optical fibers (hair-thin glass filaments) protected by a plastic sheath and outer sheath. They contain no metals such as gold, silver, copper, or aluminum and are generally not worth recycling. Optical fiber cables are communications lines composed of a number of optical fibers arranged in a specific pattern, surrounded by a sheath and, in some cases, an outer protective layer, to transmit optical signals. Existing optical fiber cables have a simple structure and low strength, making them susceptible to damage when subjected to external forces. Utility Model Content
