Abstract
The invention discloses a high-strength submarine optical cable which comprises three parallel cable cores. The outer surface of each cable core is provided with an insulating layer, a first waterproof layer, a first reinforcing protective layer, a second waterproof layer, an inner shielding layer, a second reinforcing protective layer, a waterproof filling layer, an outer shielding layer, a third reinforcing protective layer, a third waterproof layer and an outer reinforcing protective jacket sequentially from inside to outside. By the mode, the high-strength submarine optical cable has the advantages of high breaking resistance and good waterproof and anticorrosion performance.
Description
Technical field
The present invention relates to the optical cable field, particularly relate to a kind of high strength submarine optical fiber cable.
Background technology
Submarine optical fiber cable is the optical fiber with wrapped with insulation, is laid on the seabed, is used for telecommunication transmission, transmission phone and internet signal.The submarine optical fiber cable design must guarantee that optical fiber is not subjected to the impact of external force and environment, can adapt to the environment such as seabed pressure, wearing and tearing, corrosion.Submarine optical fiber cable is most important in design process to be exactly the anti-fracture strength of optical cable and the Corrosion Protection that blocks water, and also there is defective in this respect in existing submarine optical fiber cable.
Summary of the invention
The technical matters that the present invention mainly solves provides a kind of high strength submarine optical fiber cable, can solve problems of the prior art, and anti-fracture strength is high, and the antiseptic property that blocks water is good.
For solving the problems of the technologies described above; the technical scheme that the present invention adopts is: a kind of high strength submarine optical fiber cable is provided; comprise: three parallel cable cores, described cable core outside surface from inside to outside are provided with insulation course, the first water blocking layer, the first heavy seal coat, the second water blocking layer, internal shield, the second heavy seal coat, the packed layer that blocks water, external shielding layer, the 3rd heavy seal coat, the 3rd water blocking layer and outer reinforcement protective sleeve successively.
In a preferred embodiment of the present invention, described the first water blocking layer, the second water blocking layer and the 3rd water blocking layer are waterstop.
In a preferred embodiment of the present invention, the described packed layer that blocks water is the fine cream that blocks water.
