Abstract
The utility model discloses a kind of coil type light unit optical cable, comprise light unit and sheathcoat, light unit comprises an aramid fiber at coil type fibre ribbon and center, coil type fibre ribbon is enclosed with material water-proof material and band outward successively, sleeve pipe, the utility model due to optical fiber be the state of optical fiber cylinder in sleeve pipe, to lean against on smooth jacket wall and to have material water-proof material to cushion, the diameter of sleeve pipe is less, the optical cable made is from heavy and light, diameter is little, and adopt 200 μm of small diameter fiber, the cable bend radii made is little, construction is laid easily, network diaphragm fibre ribbons is with fine heat sealing machine once to whole optical fiber welding in fibre ribbon by being clamped in of mould simultaneously, it is convenient and swift when construction continues.
Description
Technical field
The utility model relates to a kind of coil type optical fibre band optical cable.
Background technology
With urban construction and communication construction development, the optical fiber of required optical cable is increasing, the above high fiber count cable of 144 core generally adopts 245 μm of optical fiber with 12 cores often pipe employing multilayer twisted synthesizing cable, execute man-hour requirement use butt fusion tool optical fiber is docked one by one, often continue the fiber cable joint of 144 cores, need the engineering time spending several hours, and cable configuration is also comparatively large, wastes time and energy during mounting and installation.Along with the development of communication construction, people investigated optical fibre band optical cable, have developed optical fiber splicer simultaneously, this heat sealing machine can say whole optical fiber welding of a fibre ribbon, make high fiber count cable welding convenient like this, but this optical fibre band optical cable also has its defect, because optical fibre band optical cable adopts Special Resin to be bonded together formation 4 some optical fiber, 6, 8, 12, the lock-in type of 24 equal-specifications or sticky limit type fibre ribbon, then some fibre ribbons are placed in sleeve pipe simultaneously, a sleeve pipe is made Central Core Optical Cable or many sleeve pipes stranded after make stranded optical fiber band optical cable, due to fibre ribbon at sleeve pipe orthogonal or rhombus arrange, the optical fiber of water caltrop easily and internal surface of sleeve pipe extrude and produce high loss point, so often diameter of inner pipe do larger, simultaneously the bending radius of fibre ribbon require more greatly and the optical fibre band optical cable made so often structure and deadweight larger when urban duct construction is laid due to from great, be laid with larger difficulty, and because crooked process radius has less than normal, disconnected fine accident that is that cause happens occasionally in work progress.
Utility model content
For above problem, the utility model discloses a kind of coil type light unit optical cable.
The technical solution adopted in the utility model is:
A kind of coil type light unit optical cable, light unit and sheathcoat is comprised in described smooth unit optical cable, described smooth unit comprises coil type fibre ribbon, and described coil type fibre ribbon center is an aramid fiber, and described coil type fibre ribbon is enclosed with material water-proof material and band, sleeve pipe outward successively.
Advantage of the present utility model: because optical fiber is the state of optical fiber cylinder in sleeve pipe, to lean against on smooth jacket wall and to have material water-proof material to cushion, the diameter of sleeve pipe is less, the optical cable made is little from heavy and light, diameter, and adopt 200 μm of small diameter fiber, the cable bend radii made is little, construction is laid easily, and network diaphragm fibre ribbons is with fine heat sealing machine once to whole optical fiber welding in fibre ribbon by being clamped in of mould simultaneously, convenient and swift when construction continues.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the light cell schematics of the utility model with multilayer winding;
Fig. 2 is layer-stranding cable schematic diagram of the present utility model.
Wherein: 1, aramid fiber; 2, coil type fibre ribbon; 3, material water-proof material and band; 4, sleeve pipe; 5, sheathcoat; 6, light unit.
Embodiment
As shown in Figure 1-2, a kind of coil type light unit optical cable, light unit 6 and sheathcoat 5 is comprised in described smooth unit optical cable, described smooth unit comprises coil type fibre ribbon 2, described coil type fibre ribbon center is an aramid fiber 1, and described coil type fibre ribbon is enclosed with material water-proof material and band 3, sleeve pipe 4 outward successively.
The utility model due to optical fiber be the state of optical fiber cylinder in sleeve pipe, to lean against on smooth jacket wall and to have material water-proof material to cushion, the diameter of sleeve pipe is less, the optical cable made is little from heavy and light, diameter, and adopt 200 μm of small diameter fiber, the cable bend radii made is little, construction is laid easily, and network diaphragm fibre ribbons is with fine heat sealing machine once to whole optical fiber welding in fibre ribbon by being clamped in of mould simultaneously, convenient and swift when construction continues.
