Detailed Description
The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
Referring to fig. 1, a schematic view of an embodiment of an easy-to-open optical cable for an outdoor testing station according to the present invention is shown. The utility model discloses an optical cable is photoelectric composite optical cable, including oversheath layer 1, optical fiber unit 2 and electric unit 3 strand each other according to certain pitch, strengthen the intensity of optical cable on the one hand, and on the other hand guarantees that optical fiber unit 2 and electric unit 3 have certain extra length, can not be broken easily at the laying process. The optical fiber unit 2 and the electric unit 3 are directly provided with a water blocking yarn 4 in the center, and the water blocking yarn 4 serves as a central reinforcing piece on one hand and prevents the optical fiber unit 2 and the electric unit 3 from water seepage on the other hand. In the embodiment, the optical fiber unit 2 and the two electric units 3 are arranged, and the arrangement of a central reinforcing piece is cancelled, so that the optical cable is simpler and lighter; secondly, the dry-type water-blocking structure of the water-blocking yarn 4 with light weight is adopted, so that the diameter of the optical cable is reduced, the structural size and the weight of the optical cable are optimized, and the material and the production cost are relatively reduced. And reinforcing layers 5 are arranged outside the optical fiber unit 2 and the electric unit 3 and used for protecting the optical fiber unit 2 and the electric unit 3 from the influence of external mechanical action and environmental conditions, and simultaneously, the tensile strength of the optical cable is enhanced, and the mechanical property of the optical cable is improved. In this embodiment, the reinforcing layer 5 is a plastic-coated steel belt. In order to further protect the optical fiber unit 2 and the electrical unit 3, an outer sheath layer 1 is arranged outside the reinforcing layer 5.
Referring to fig. 1 and 2, in the present embodiment, in order to facilitate stripping the optical cable, grooves 6 are alternately formed on both sides of the outer sheath layer 1 along the axial direction. Because the thickness of the outer sheath layer 1 at the position of the groove 6 is smaller, the outer sheath layer 1 is easily torn from the position of the groove 6, and therefore the core at the end part of the optical cable is exposed. Because the grooves 6 are discontinuous, only the positions of the end grooves 6 can facilitate tearing, and the optical cable is prevented from being excessively torn to influence the use of the optical cable. Further, in order to prevent the optical cable from being excessively torn and ensure the torn length to be convenient for operation, the length of each groove 6 is set to be 5-10cm in the embodiment. Meanwhile, the grooves 6 are alternately arranged on the two sides of the outer sheath, namely the grooves 6 are continuous in the axial direction, so that the grooves 6 which are easy to tear at one end always exist at the end part of the optical cable no matter where the optical cable is cut off. To facilitate tearing the cable for longer lengths, in this embodiment a tear string 7 is provided in the gap between the reinforcing layer 5 and the fibre unit 2 or the electrical unit 3. After the groove 6 at the end part is torn, the end part of the tearing rope 7 is exposed, and the optical cable can be conveniently pulled and torn continuously by pulling the tearing rope 7. In order to ensure the strength of the tear string 7, in this embodiment, the tear string 7 is made of high-strength low-density polyester fiber. The presence of the ripcord 7 in the reinforcement layer 5 in this embodiment also protects the tear from infestation by eggs.
Referring to fig. 3, in order to further prevent the problem of oil contamination of the optical cable during splicing, a water blocking yarn 4 is filled in the gap between the optical fiber unit 2 and the electrical unit 3 or between the electrical unit 3 and the electrical unit 3. The gaps among the optical fiber unit 2, the electric unit 3 and the reinforcing layer 5 are filled, and the stability of the optical fiber unit 2 and the electric unit 3 in the reinforcing layer 5 is ensured. Furthermore, a longitudinal wrapping water-blocking tape 8 is arranged outside the optical fiber unit 2 and the electric unit 3, and the reinforcing layer 5 is arranged outside the water-blocking tape 8. The water-blocking and moisture-proof performance of the whole cross section of the optical cable and the ultraviolet aging resistance are ensured, and the requirement of the field pipeline wiring of the optical cable is met.
Referring to fig. 1 and 3, the optical fiber unit 2 includes an optical fiber bundle 9, a loose tube 10, and a polyester tape 11, the optical fiber bundle 9 being disposed inside the loose tube 10, the polyester tape 11 being wrapped outside the loose tube 10. The loose tube 10 is filled with fiber paste. Forming a protection for the bundle 9. 4-12 optical fibers are arranged in the optical fiber bundle 9, and the optical fibers are microbend-resistant optical fibers. The corner wiring can be realized, and the harsh wiring requirement can be met.
The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
