Abstract
The utility model relates to a communication material, in particular to a cable for both an outdoor system and an indoor system in the optical fiber broadband access (FTTx) network engineering of the communication network. The utility model is characterized in that at least one optical fiber is wrapped with an enhancement sleeve, and the enhancement sleeve is wrapped by a protective sleeve. The cable improves the safety protection property for communication facilities and user terminal equipment; and particularly the cable diameter is tiny, and the curvature radius is small, so that the special requirements of the optical fiber broadband access (FTTx) network engineering, such as easy branching, easy accessing and convenient construction, can be met.
Description
Technical field:
The utility model relates to a kind of communication material, especially relates to the outdoor system of fiber broadband access (FTTx) network engineering in a kind of communication network and the optical cable of indoor heating system.
Background technology:
At present, transmit the main adopting quartz glass optical fiber of optical cable of communication signal, and all adopt the enhancement measures of naked fine surface-coated resin.There is the very low defective of tensile strength owing to apply its material of resin on naked fine surface, so, be around its optical fiber, to add some reinforcements in order to improve the tensile strength of optical cable.In addition, for protection against the tide, the water-impervious performance that satisfies optical cable, also will be around optical fiber parcel or fill waterproof material, thereby its manufacturing process complexity, optic cable diameter is big, quality is heavy, radius-of-curvature is big, the cost costliness, and fill waterproofing unction and easily environment is caused secondary pollution.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of prior art structure defective of having overcome, and can hold and cut big tensile strength, need not to add waterproof material, low cost of manufacture, the optical cable that radius-of-curvature is little.The technical scheme that its technical matters that solves the utility model adopts is: a kind of optical cable, it is parcel enhancing cover on an optical fiber at least, strengthens cover outer wrapping protective sleeve.Technical problem to be solved in the utility model also can further be solved by following technical solution: strengthen cover and adopt fibre reinforced plastics, the manufactured materials of fibre reinforced plastics and preparation method see the patent of invention " a kind of optical cable and the preparation method who is used for the fibre reinforced plastics and the fibre reinforced plastics of this optical cable " that the applicant applies on the same day for details.The utility model wraps up on optical fiber and strengthens cover and can adopt existing thermosetting, thermoplastic composite pultrusion technique at enhancing cover outer wrapping protective sleeve.The utility model is owing to adopt technique scheme, except having good tensile strength, lateral pressure resistant intensity, anti-electromagnetic field jamming performance, improve the Optical Fiber Transmission data stability, prolonged optical cable outside serviceable life, also has good impervious water permeability, need not to fill waterproof material, avoided second environmental pollution; And owing to adopt full dielectric material, can resist lightning-arrest hitting effectively, improve the security protection performance of communications service and subscriber terminal equipment; Especially the cable footpath is trickle, and radius-of-curvature is little, can satisfy the specific (special) requirements that fiber broadband inserts easily branched, the easy access of (FTTx) network engineering, easy construction.The utility model has not only demonstrated fully optical cable self-bearing type, full medium, dry type and microminiaturized development trend, and simple in structure, and processing is convenient, has both saved natural resources, has reduced production cost again.
Description of drawings:
Below in conjunction with accompanying drawing and specific embodiment of the utility model the utility model is described in further detail:
Fig. 1, Fig. 2 are cross-sectional structure synoptic diagram of the present utility model.
Embodiment
With reference to Fig. 2, parcel strengthens cover 2 on the optical fiber 1 of the present utility model, strengthens cover 2 outer wrapping protective sleeves 3.
Embodiment 1: with reference to Fig. 1.On an optical fiber, wrap up the enhancing cover and, can realize the goal of the invention of utility model by existing thermosetting, thermoplastic composite pultrusion technique at enhancing cover outer wrapping protective sleeve and because of the enhancing cover adopts fibre reinforced plastics.
Embodiment 2: with reference to Fig. 2.By existing thermosetting, thermoplastic composite pultrusion technique on two (comprising more than two) optical fiber respectively parcel strengthen cover and, can realize goal of the invention of the present utility model strengthening cover outer wrapping protective sleeve and adopting fibre reinforced plastics because of strengthening cover.
The utility model after testing, its pulling strengrth: 1403MPa, breaking elongation: 3.18%, minimum bending radius: 8mm.
Claims (2)
1. optical cable is characterized in that: it at least on an optical fiber parcel strengthen cover, strengthen cover outer wrapping protective sleeve.
2. a kind of optical cable according to claim 1 is characterized in that: strengthen cover and adopt fibre reinforced plastics.
