Abstract
The utility model relates to a bone-dry type waterproofing universal indoor and outdoor optical cable, which comprises a cable core and an outer protective sleeve, wherein a plurality of optical fiber units are arranged in the cable core, a center reinforcing element and waterproofing gauze are arranged in the cable core, a cable core waterproofing strip layer and an aluminum strip reinforcing layer are arranged between the cable core and the outer protective sleeve, a tight sheathing layer is covered outside the optical fiber of each optical fiber unit, and a waterproofing layer and a protective sleeve layer are sequentially covered outside the tight sheathing layer. After being paved into a high building, the bone-dry type waterproofing universal indoor and outdoor optical cable can be directly branched into each user terminal without being firstly connected into a distributing box in the building and then being connected to each user terminal, so the operation is convenient and fast. No ointment is filled in the optical cable, so no ointment flows out during branching operation, the pollution is avoided, and the utility model is also suitable for indoor vertical wire distribution. The optical cable has good waterproofing performance.
Description
Technical field
The utility model relates to a kind of optical cable, especially the general optical cable in dry type waterproofing type indoor and outdoor.
Background technology
The general optical cable in existing indoor and outdoor the outer general loose sleeve structure that adopts of optical fiber, factice for filling in the optical cable, fiber cable laying can't direct descendant be received each user terminal after entering building, can only receive cross-connecting box in the building, is forwarded to each user terminal again.Workload is increased; And, optical cable when switching ointment wherein can flow out, environment and operator are polluted; Because the ointment in the optical cable can flow, and also is unsuitable for indoor vertical wirings.
Summary of the invention
In order to overcome the deficiency of the general optical cable in existing indoor and outdoor, the utility model provides a kind of dry type waterproofing type indoor and outdoor general optical cable, after entering building, can direct descendant receive each user terminal, not need to receive earlier and be forwarded to each user terminal in the building behind the cross-connecting box again, convenient and swift; Do not have ointment in the optical cable, when branch, do not have ointment and flow out, do not pollute, be suitable for indoor vertical wirings yet.
The general optical cable in dry type waterproofing type indoor and outdoor that the utility model provides, comprise cable core and oversheath, cable core contains several fiber units, be provided with central reinforce member, water blocking yarn in the cable core, between cable core and oversheath, be provided with the aluminium strip enhancement Layer, the optical fiber of each fiber unit coats tight sleeve layer outward, coats water blocking layer and restrictive coating outside tight sleeve layer successively.
In order to strengthen block-water performance of the present utility model, between cable core and aluminium strip enhancement Layer, be provided with the cable core water blocking tape layer.
The beneficial effects of the utility model are: fiber cable laying can direct descendant be received each user terminal after entering building, does not need to receive earlier to be transferred to each user terminal in the building behind the cross-connecting box again, and is convenient and swift; Do not have ointment in the optical cable, when branch, do not have ointment and flow out, do not pollute, be suitable for indoor vertical wirings yet; The block-water performance of optical cable is good.
Description of drawings
Fig. 1 is a cross sectional representation of the present utility model.
In Fig. 1,1, optical fiber, 2, the optical fiber tight sleeve layer, 3, water blocking layer, 4, restrictive coating, 5, water blocking yarn, 6, central reinforce member, 7, the cable core water blocking tape layer, 8, the aluminium strip enhancement Layer, 9, oversheath, 10, cable core, 11, fiber unit.
Embodiment
With reference to Fig. 1, the optical fiber of each fiber unit 11 of the present utility model 1 outer optical fiber tight sleeve layer 2 that constitutes by polyurethane elaster that coats, the restrictive coating 4 that outside optical fiber tight sleeve layer 2, coats the water blocking layer 3 that constitutes by the glass yarn that blocks water successively, makes by polyolefine material.Several fiber units 11 are twisted into cable core 10 with central reinforce member 6, water blocking yarn 5, outside cable core 10, coat cable core water blocking tape layer 7, aluminium strip enhancement Layer 8 and oversheath 9 more successively, promptly make the utility model.
Claims (2)
1. general optical cable in dry type waterproofing type indoor and outdoor, comprise cable core and oversheath, cable core contains several fiber units, be provided with central reinforce member, water blocking yarn in the cable core, between cable core and oversheath, be provided with the aluminium strip enhancement Layer, the optical fiber that it is characterized in that each fiber unit coats tight sleeve layer outward, coats water blocking layer and restrictive coating outside tight sleeve layer successively.
