Abstract
The utility model relates to an skeleton-type optical cable with micro-clusters, including oversheath and cable core, its characterized in that the cable core include the skeleton, the micro-cluster unit has been installed to the skeleton inslot of skeleton, the beneficial effects of the utility model reside in that 1, adopt the rigid-flexible structure that skeleton and micro-cluster unit combined together, make the optical cable have the advantage that the optic fibre integrated level is high, easy divergence is convenient for indoor laying and continuing, 2, skeleton-type optical cable has higher resistance to compression tensile strength, can provide fine protection to the micro-cluster unit, makes it be suitable for the use and the laying of various indoor and outdoor environment, 3, can also lay power wire and/or signal line in the cable, can make to lay and use more convenient.
Description
Technical Field
The utility model relates to an skeleton type optical cable that micro-clusters belongs to optical communication transmission technical field.
Background
The micro-cluster unit adopting soft materials such as TPE, TPEE, TPU, PVC and the like as the protective sleeve is favored by users due to the advantages of higher optical fiber integration level, easy tearing, convenient manual branching and the like, and is suitable for application occasions such as FTTH access networks and the like, but because the sleeve is softer, the sleeve adopts a conventional layer-stranded optical cable structure, has lower strength, ensures that the application of the sleeve is limited by standards, and can only be used indoors or outdoor occasions with low requirements on the optical cable strength.
Disclosure of Invention
The utility model aims to solve the technical problem that not enough and provide kinds of skeleton-type optical cable in micro cluster exists to above-mentioned prior art, this optical cable branch not only is convenient for, and the optic fibre integrated level is high, and the sleeve pipe is flexible good, and optical cable compressive tensile strength is high moreover, enables the unit in micro cluster and obtains abundant protection, can be suitable for the use of various indoor and outdoor environment and lay.
The utility model discloses a solve the technical scheme that the problem that the aforesaid provided adopted and be: the cable comprises an outer sheath and a cable core and is characterized in that the cable core comprises a framework, and a micro-cluster unit is arranged in a framework groove of the framework.
According to the scheme, the micro-cluster unit is formed by sleeving optical fibers with flexible sleeves, and the flexible sleeves are made of TPE (thermoplastic elastomer), TPEE (thermoplastic elastomer), TPU (thermoplastic polyurethane) or PVC (polyvinyl chloride).
According to the scheme, the number of the optical fiber cores of each micro-cluster unit is 2-48 cores.
According to the scheme, the thickness of the single side of the flexible sleeve is 0.1-0.2 mm.
According to the scheme, 4-8 framework grooves are distributed along the circumferential direction, and the radial sections of the framework grooves are rectangular or C-shaped.
According to the scheme, 2-144 micro-cluster units are laid in the framework groove.
According to the scheme, a power supply lead and/or a signal wire are laid in the framework groove.
According to the scheme, the steel wire or nonmetal reinforcing piece is arranged at the center of the framework, the cable core is wrapped by layers of water-blocking tapes, and the outer side of the cable core is provided with the outer sheath.
The beneficial effects of the utility model reside in that: 1. the rigid-flexible structure combining the framework and the micro-cluster units is adopted, so that the optical cable has the advantages of high optical fiber integration level, easiness in branching and convenience in indoor laying and connection; 2. the skeleton type optical cable has higher compression strength and tensile strength, can provide good protection for the micro-cluster unit, and is suitable for use and laying in various indoor and outdoor environments; 3. the cable can also be provided with power supply leads and/or signal wires, so that the cable is more convenient to lay and use.
Drawings
