Abstract
The utility model discloses a small-cross-section-dimension wireless radio frequency remote optical cable. The small-cross-section-dimension wireless radio frequency remote optical cable comprises a sheath. Two to four single-core tight buffered optical fibers are arranged inside the sheath. Nonmetal reinforcement materials fill between the single-core tight buffered optical fibers and the sheath. The small-cross-section-dimension wireless radio frequency remote optical cable of the utility model is compact in structure, small in external diameter, light in weight and small in bending radius. The small-cross-section-dimension wireless radio frequency remote optical cable is also soft, and is excellent in stretching strain performance. The small-cross-section-dimension wireless radio frequency remote optical cable is easy to lay and can different usage performance requirements in indoor environments and outdoor conditions. Ends of the small-cross-section-dimension wireless radio frequency remote optical cable can be directly made into movable joints or to be directly connected with standard joints, and the usage is relatively convenient.
Description
Technical field
the utility model relates to a kind of transmission cable that wireless radio remote unit is used that is applicable to.
Background technology
between the machine room that less radio-frequency dragging optical cable is mainly used in communication base station and antenna for base station, Optical Fiber Transmission route is connected.At present, conventionally use dragging optical cable to support special plug/unplug connector, therefore require the transmission medium of dragging optical cable to adopt tight tube fiber.
as shown in Figure 1, existing less radio-frequency dragging optical cable comprises multiple tight tube fibers 01, multiple gasket for packings 02, nonmetal reinforcement material 03 and sheath 04, described tight tube fiber 01 is coated with stiffener 05 and sub-cable sheath 06 and forms sub-cable, spaced apart and the stranded formation cable core of described sub-cable and gasket for packing 02, described sheath 04 is coated on outside above-mentioned cable core, described nonmetal reinforcement material 03 is filled in sub-cable, between gasket for packing 02 and sheath 04, the less radio-frequency dragging optical cable of this kind of structure is all take the sub-cable of diameter 2.0mm as subelement, entire outer diameter is 7.mm, its size is larger, when bending, feel harder, transportation, construction is trouble relatively, while making connector at this kind of optical cable two ends simultaneously, cumbersome.
Summary of the invention
the utility model object is: a kind of small bore size less radio-frequency dragging optical cable is provided, its compact conformation, external diameter is little, lightweight, soft, bending radius is little, stress, strain property are good, be easy to lay, can meet the different usability requirements of indoor environment and outdoor conditions simultaneously, directly creative activity connector or be directly connected with modular connection of its termination, uses more in addition.
the technical solution of the utility model is: a kind of small bore size less radio-frequency dragging optical cable, comprise sheath, and in described sheath, be provided with 2-4 root list core tight tube fiber, between described single core tight tube fiber and sheath, be filled with nonmetal reinforcement material.
further, described nonmetal reinforcement material is water resistance aramid fiber fiber; Described sheath adopts low smoke halogen-free flame-retardant polyolefin (LSZH), polyurethane (TPU) or high density polyethylene (HDPE) material to make; The diameter of described single core tight tube fiber is 0.6-0.9mm.Wherein, the effect of described nonmetal reinforcement material is the longitudinal water-blocking effect for ensureing sheath, and increases the longitudinal tensile strength of optical cable.Adopt these nonmetal reinforcement materials, can meet the compatibility of itself and tight tube fiber, and can not produce influence of fading.
the utility model has the advantages that: the utility model compact conformation, external diameter is little, lightweight, soft, bending radius is little, tensile strain function admirable, be easy to lay, can meet the different usability requirements of indoor environment and outdoor conditions simultaneously, directly creative activity connector or be directly connected with modular connection of its termination, uses more in addition.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is further described:
fig. 1 is the schematic cross-section of existing less radio-frequency dragging optical cable;
fig. 2 is schematic cross-section of the present utility model.
wherein: 01 tight tube fiber; 02 gasket for packing; 03 nonmetal reinforcement material; 04 sheath; 05 stiffener; 06 sub-cable sheath;
1 single core tight tube fiber; 2 nonmetal reinforcement materials; 3 sheaths.
Embodiment
embodiment: as shown in Figure 2, a kind of small bore size less radio-frequency dragging optical cable, comprises sheath 3, is provided with 2-4 root list core tight tube fiber 1 in described sheath 3, is filled with nonmetal reinforcement material 2 between described single core tight tube fiber 1 and sheath 3.Described nonmetal reinforcement material 2 is water resistance aramid fiber fiber; Described sheath 3 adopts the materials such as low smoke halogen-free flame-retardant polyolefin (LSZH), polyurethane (TPU), high density polyethylene (HDPE) to make; The diameter of described single core tight tube fiber 1 is 0.6-0.9mm.Wherein, the effect of described nonmetal reinforcement material 2 is the longitudinal water-blocking effects for ensureing sheath 3, and increases the longitudinal tensile strength of optical cable.Adopt these nonmetal reinforcement materials 2, can meet the compatibility of itself and tight tube fiber 1, and can not produce influence of fading.
the utility model compact conformation, external diameter is little, lightweight, soft, bending radius is little, stress, strain property are good, be easy to lay, can meet the different usability requirements of indoor environment and outdoor conditions simultaneously, directly creative activity connector or be directly connected with modular connection of its termination, uses more in addition.
below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on the utility model scope required for protection.
