Abstract
The utility model discloses a nonmetallic loose-tube-layer stranded optical cable. The nonmetallic loose-tube-layer stranded optical cable comprises optical fibers. The central part of the nonmetallic loose-tube-layer stranded optical cable is provided with a nonmetallic reinforcing member, around which the plurality of optical fibers are arranged. Each of the plurality of optical fibers is sleeved with a PBT loose tube. Fiber grease is filled between each optical fiber and each PBT loose tube. The PBT loose tubes are externally wrapped by a waterproof cable compound layer, the external of which is wrapped with a wrapping tape layer. The wrapping tape layer is externally wrapped by an aramid yarn layer, which is externally wrapped by an MDPE outer sheath. The nonmetallic reinforcing member is a wire body made of fiber reinforced plastics (FRP). Through the addition of the aramid yarn layer and the wrapping tape layer in the MDPE outer sheath, the nonmetallic loose-tube-layer stranded optical cable of the utility model achieves excellent flexibility and anti-bending ability and therefore has good mechanical performance and environmental performance. The waterproof cable compound is filled outside the reinforcing member and inside the cable core, guaranteeing the moistureproof and waterproof effects. The whole optical cable, free of nonmetallic materials, is light in weight and excellent in anti-electromagnetic-interference ability and is suitable for long-distance communication and strongly electromagnetic places.
Description
Technical field:
The utility model relates to field fiber, relates in particular to a kind of nonmetal loose jacketed stranded optical cable.
Background technology:
Existing optical cable mostly is the optical fiber overcoat sleeve pipe, and cooperates the structure of oversheath, and its mechanical property is relatively poor, easily go wrong when growing apart from backguy, secondly cable outer sheath adopts the PE sheath usually, and its pressure-proof and snap-resistent ability is relatively poor, in case dug or bumped, be easy to occur the situations such as breakage, fracture by mistake by mistake.Therefore imagination provides a kind of new construction to solve this problem.
The utility model content:
The purpose of this utility model just provides a kind of nonmetal loose jacketed stranded optical cable, the existing optical cable of solution mostly is the optical fiber overcoat sleeve pipe, and the structure of cooperation oversheath, its mechanical property is relatively poor, easily go wrong when growing apart from backguy, secondly cable outer sheath adopts the PE sheath usually, and its pressure-proof and snap-resistent ability is relatively poor, in case dug or bumped, be easy to occur the problem of the situations such as breakage, fracture by mistake by mistake.
The technical solution adopted in the utility model is:
A kind of nonmetal loose jacketed stranded optical cable, comprise optical fiber: central part has non-metal reinforcement member, make a circle in non-metal reinforcement member week and have some optical fiber, some optical fiber all are set with PBT pine sleeve pipe outward, be filled with fine cream between optical fiber and the PBT pine sleeve pipe, all PBT pine sleeve pipes are wrapped with the cable cream layer that blocks water, and the cable cream layer that blocks water is wrapped with belting layer, belting layer is wrapped with the aramid fiber layer, and the aramid fiber layer is wrapped with the MDPE oversheath.
Described non-metal reinforcement member is the line body that fibre-reinforced plastics (FRP) is made.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is by increasing the structure of aramid fiber layer and belting layer in the MDPE oversheath, pliability and counter-bending ability are good, can make optical cable have good mechanical property and environmental performance; Be full of the cable cream that blocks water outside the reinforcement and in the cable core, guarantee protection against the tide, block-water effect, whole cable is without metal material, and is lightweight, and anti-electromagnetic capability is good, is applicable to long distance communication and strong electromagnetic place.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Embodiment:
Below in conjunction with accompanying drawing, by embodiment the utility model is described in further detail:
A kind of nonmetal loose jacketed stranded optical cable, comprise optical fiber: central part has non-metal reinforcement member 1, make a circle in 1 week of non-metal reinforcement member and have some optical fiber 2, the some optical fiber 2 outer PBT pine sleeve pipes 3 that all are set with, be filled with fine cream 4 between optical fiber 2 and the PBT pine sleeve pipe 3, all PBT pine sleeve pipes 3 are wrapped with the cable cream layer 5 that blocks water, the cable cream layer 5 that blocks water is wrapped with belting layer 6, belting layer 6 is wrapped with aramid fiber layer 7, aramid fiber layer 7 is wrapped with MDPE oversheath 8, the line body that non-metal reinforcement member 1 is made for fibre-reinforced plastics (FRP).
Above-described embodiment only is better embodiment of the present utility model, and in addition, the utility model can also have other implementations.Need to prove, under the prerequisite that does not break away from the utility model design, any apparent improvement and modification all should fall within the protection domain of the present utility model.
