The invention discloses a miniature indoor optical distribution cable with good mechanical properties. The miniature indoor optical distribution cable with the good mechanical properties comprises anouter sheath, the inner wall of the outer sheath is bonded with a wrapping tape by an adhesive, one side of the wrapping tape is bonded with a tear rope, unit cables are arranged on the inner wall ofthe outer sheath, a cushion layer is arranged between the opposite sides of the two unit cables, a strengthening core is fixedly connected into the cushion layer, the unit cables comprise inner sheaths, tight buffered fibers are arranged on the inner walls of the inner sheaths, the inner parts, located on the surfaces of the tight buffered fibers, of the inner sheaths are filled with aramid yarns,the outer sheath is a low smoke halogen-free sheath, and the invention relates to the technical field of optical distribution cable. According to the miniature indoor optical distribution cable withthe good mechanical properties, the strengthening core is strengthened for protecting by adopting the aramid yarns, lateral compression resistance and impact resistance properties of the optical cableare improved, prepared sheath materials have the good wear-resisting property, the service life is greatly prolonged, cost inputting is small, environmental protection is realized, and the economic benefit is improved.
Description
technical field [0001] The invention relates to the technical field of distribution optical cables, in particular to a miniature indoor distribution optical cable with good mechanical properties. Background technique [0002] Indoor distribution optical cable is an indoor optical cable suitable for the distribution and wiring of optical cables in the central office and the integrated wiring of optical cables for urban buildings. The design of the indoor optical cable requires that the signal be fully Considering the mechanical performance requirements of the optical cable under the indoor operating environment conditions, such as twist resistance, extrusion resistance, impact resistance and tensile resistance, as well as the interference effect of electromagnetic field radiation on the signal in the optical fiber in the space application environment, and the air Hydrogen-oxygen (-OH) in water vapor directly invades the optical fiber. It adopts a new structural design and pro...
