Embodiment Construction
[0023] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] Such as figure 2 As shown, it is a multi-scenario indoor wiring optical cable, which adopts a micro flexible optical cable 10 structure, and is mainly used for floor level optical cable wiring. The miniature flexible optical cable 10 includes a first core 16 located at the center, and a strengthening layer 12 and a sheath 11 covering the first core 16 sequentially. The reinforcing layer 12 is made of non-metallic fiber material, such as aramid fiber. The thickness of the sheath 11 is greater than or equal to 0.3 mm, and its material is low-smoke halogen-free polyolefin, including flame-retardant materials such as polyvinyl chloride and acrylic resin.
[0025] The first cable core 16 includes a plurality of micro-tight-bu...

Abstract
The invention relates to a multi-scenario indoor wiring optical cable including a micro flexible optical cable and a large-core-number flexible optical cable. The micro flexible cable includes a first cable core, and a reinforcing layer and a sheath which successively coat the outside of the first cable core. The first cable core includes a plurality of micro-tightening optical fiber units, each of which is composed of an optical fiber and a tight sleeve coating the optical fiber. The large-core-number flexible optical cable comprises a second cable core, and a wrapping tape layer and an outer sheath successively coating the second cable core. The second cable core comprises a center reinforcement member and a plurality of the micro flexible optical cables twisted outside the center reinforcement member. The multi-scenario indoor wiring optical cable has small outer diameter and better bending flexibility compared with a conventional optical cable with the same core capacity, can be arranged in narrow wire ducts, dark pipes and dark boxes in buildings, and has more wiring scenarios than a conventional optical cable.
Description
technical field [0001] The invention relates to a communication optical cable for supporting an indoor passive optical network (ODN) integrated wiring system of a commercial complex (commercial office building, professional cluster market, etc.), specifically a multi-scenario indoor wiring optical cable. Background technique [0002] With the implementation of the national "Broadband China" strategy, accelerating the upgrading of broadband networks, promoting fiber-optic access to households, and coordinating the improvement of urban broadband network penetration and access capabilities have become the focus of telecommunications infrastructure construction. [0003] The large-scale development of optical fiber access network construction and the wide application of FTTH / FTTO technology will gradually realize the full coverage of FTTH / FTTO and realize the large-scale and efficient development of FTTH / FTTO. In the construction and transformation of FTTH / FTTO, at present, a la...
