Abstract
The utility model relates to a communication apparatus and aims to provide a cable with a nonmetal reinforcing belt. The cable comprises an optical fiber or an optical fiber belt enclosed and protected by fiber paste, wherein a loose tube sleeve is wrapped outside the fiber paste and a jacket is wrapped at the outermost layer. The cable is characterized in that a layer of nonmetal reinforcing belt is also arranged between the loose tube sleeve and the jacket. The utility model has the advantages that: (1) the cable cannot be struck by lightning; (2) the cable cannot enable the optical fiber to have hydrogen loss because of the oxidation of parkerising steel wires or steel strips to lead to the significant increase of the transmission loss of the cable; (3) the cable can be used under the environment with strong electromagnetic field; and (4) the cable plays the roles of moisture protection, stretching resistance, side compression resistance, shock resistance, and the like.
Description
Technical field
The utility model relates to a kind of communication apparatus.More particularly, the utility model relates to a kind of optical cable with non-metal reinforcing band.
Background technology
Traditional optical cable generally adopts phosphatization steel wire or phosphatization steel band to twine braiding as reinforcement between sandwich layer and outermost sheath.Though this mode can have than hard intensity, also has following shortcoming: subject to thunderbolt; Can make optical fiber suffer hydrogen loss because of the oxidation of phosphatization steel wire or steel band, thereby cause the loss of optical cable significantly to increase; Influence is used under the environment of strong-electromagnetic field.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of optical cable with non-metal reinforcing band is provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The optical cable with non-metal reinforcing band that the utility model provides comprises the optical fiber or the fibre ribbon of being gone along with sb. to guard him by fine cream, fine cream outer wrapping pine pipe box, and the outermost layer wrap jacket also has one deck non-metal reinforcing band between loose pipe box and sheath.
As a kind of improvement, described non-metal reinforcing band is the glass fiber reinforced plastics band.
As a kind of improvement, described non-metal reinforcing band vertically surrounds along optical cable.
Compared with prior art, the beneficial effects of the utility model are:
(1) can be struck by lightning; (2) can not make optical fiber suffer hydrogen loss because of the oxidation of phosphatization steel wire or steel band, thereby cause the loss of optical cable significantly to increase; (3) under the environment of strong-electromagnetic field, also can use; (4) play moistureproof, anti-ly open, effects such as lateral pressure resistant and shock resistance.
Description of drawings
Fig. 1 is a horizontal section synoptic diagram of the present utility model.
Among the figure, 1-optical fiber or fibre ribbon, the fine cream of 2-, 3-pine pipe box, 4-non-metal reinforcing band, 5-sheath
Embodiment
With reference to the accompanying drawings, will be described in detail the utility model below.
The optical cable with non-metal reinforcing band in the present embodiment comprises the optical fiber or the fibre ribbon of being gone along with sb. to guard him by fine cream, fine cream outer wrapping pine pipe box, and the outermost layer wrap jacket also has one deck non-metal reinforcing band between loose pipe box and sheath.Non-metal reinforcing band is the glass fiber reinforced plastics band, vertically surrounds along optical cable.
With the butt joint of non-metal reinforcing band side, the heat that utilizes sheath is produced the various optical cable of structure to the reinforcement pipe of a driving fit of the bonding one-tenth of reinforcing band so can design during vertical the bag.
This cable configuration compactness, production technology are simple.Present domestic optical cable manufacturer utilizes existing equipment to produce, and need not to add any servicing unit.
Following table is a kind of typical structure parameter of 12 core optical cables:
| Title | Beam tube external diameter (mm) | Beam tube thickness (mm) | Reinforcing band (pipe) thickness (mm) | Jacket thickness (mm) | Cable outer diameter (mm) | Optical cable weight (kg) |
| |
3 | 0.5 | 0.7 | 1.0 | 6.4 | 35 |
This optical cable has following characteristics:
1. cost has reduced 5-30%,,
2. physical dimension is little.Compare with tradition, cross-sectional area dwindles 60-70.
3. in light weight.Compare with traditional structure, weight reduces 60-70%.
4. weather resistance is good, high temperature performance is excellent; When low temperature, the contraction of no sheath and beam tube.
5. protection against rodents, mosquito-proof, shellproof.
7. good bending property.
8. be nonconductive optical fiber cable.
9. outdoor general with the city.
10. meet existing corresponding optical cable standard.
11. the lateral pressure resistant function admirable, 〉=4500N/10mm. can directly buried installation.
At last, it is also to be noted that what more than enumerate only is specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
Claims (3)
