Abstract
The utility model provides a small-outer-diameter communication air-blowing optical cable and relates to an optical cable, which comprises a central reinforcing assembly. The central reinforcing assembly is in the form of a non-metallic reinforcing assembly. The optical cable also comprises a plurality of optical fiber assemblies. Each optical fiber assembly comprises a plurality of optical fibers, the fiber paste and a loose tube, wherein the optical fibers are directly arranged in the loose tube and the fiber paste is filled between the loose tube and the optical fibers. The optical cable also comprises tying yarns, the cable paste and a PE outer sheath layer. The optical fiber assemblies are twisted together around the central reinforcing assembly. The optical fiber assemblies and the central reinforcing assembly are lapped by means of the tying yarns. The cable paste is filled among the tying yarns, the optical fiber assemblies and the central reinforcing assembly. The outermost layer of the optical cable is coated with the PE outer sheath layer. According to the technical scheme of the utility model, compared with traditional optical cables, the small-outer-diameter communication air-blowing optical cable is smaller in outer diameter, lighter in self-weight and lower in pipe consumption. Meanwhile, the small-outer-diameter communication air-blowing optical cable is good in high/low temperature performances and excellent in high-side-pressure performance.
Description
Technical field
The utility model relates to a kind of optical cable, relates in particular to a kind of air-blowing optical cable.
Background technology
Communications optical cable is the main transmission medium of social various Information Networks now.Traditional communications optical cable structural rigidity is large, emits rear one-tenth spring-like from dish tool, becomes " C " font after bending, easily causes pipeline crowded in the time laying, and pipeline can not be used to greatest extent.In addition, along with the development of communication network, original conduit resource cannot satisfy the demands, and newly-built communication pipe face cost high, destroy the problems such as periphery traffic and environment.
Utility model content
The purpose of this utility model is to propose little external diameter communication air-blowing optical cable for the problems referred to above; This little external diameter communication air-blowing optical cable, little, the soft lightweight of diameter, and the characteristic of air-blowing optical cable itself can solve the problem that conduit resource is inadequate.
The technical solution of the utility model is as follows:
The utility model is little external diameter communication air-blowing optical cable:
Comprise central reinforce member, described central reinforce member is non-metal reinforcement member;
Also comprise some optical fiber components, described optical fiber component comprises some optical fiber, fine cream and loose sleeve pipe; Described optical fiber direct amplification, in loose sleeve pipe, and is filled by fine cream between loose sleeve pipe and optical fiber;
Also comprise and prick yarn, cable cream and PE outer jacket;
Described optical fiber component is stranded around central reinforce member, and described bundle yarn, by wrapped to optical fiber component and central reinforce member, is filled by cable cream between described bundle yarn, optical fiber component and central reinforce member; Outermost is being coated PE outer jacket again.
More preferably, the material of described central reinforce member is FRP.
Beneficial effect:
The utility model is less than conventional cable external diameter, from heavy and light, the few conduit resource of joint, also has good high temperature performance and does side pressure performance.
Brief description of the drawings
Fig. 1 is cross-sectional view of the present utility model.
Embodiment
Now to be described further the utility model with accompanying drawing in order better illustrating in conjunction with the embodiments, to should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model is little external diameter communication air-blowing optical cable:
Comprise central reinforce member 1, described central reinforce member 1 is non-metal reinforcement member, and central reinforce member 1 keeps soft lightweight for non-metal reinforcement member can make little external diameter communication air-blowing light; Also comprise some optical fiber components, described optical fiber component comprises some optical fiber 2, fine cream 3 and loose sleeve pipe 4; Described optical fiber 2 is directly put in loose sleeve pipe 4, and is filled by fine cream 3 between loose sleeve pipe 4 and optical fiber 2; Also comprise and prick yarn 6, cable cream 5 and PE outer jacket 7; Described optical fiber component is stranded around central reinforce member 1, and described bundle yarn 6, by wrapped to optical fiber component and central reinforce member 1, is filled by cable cream 5 between described bundle yarn 6, optical fiber component and central reinforce member 1; Outermost is being coated PE outer jacket 7 again.More preferably, the material of described central reinforce member 1 is FRP.
