Description

Technical Field

[0001] The utility model relates to the field of optical cables, in particular to a composite optical cable. Background Art

[0002] Optical cable, also known as fiber optic cable, is a communication cable used for long-distance, high-speed data transmission. It communicates based on the transmission of optical signals by optical fibers. Optical cables are composed of multiple optical fibers. These optical fibers are made of extremely fine glass or plastic fibers and can conduct light pulses to transmit information. The core part of the optical cable is composed of a core, a cladding, and a protective layer. The core is the part that transmits the optical signal. The refractive index of the cladding is lower than that of the core, which is used to keep the optical signal reflected and propagated in the core. The protective layer protects the optical fiber from physical damage. Composite optical cable, also known as optoelectronic composite cable, integrated optical cable or optical fiber composite overhead ground wire, is a new type of optical cable that combines the functions of optical fiber communication with power transmission, overhead ground wire and other functions. It not only transmits data signals, but also can meet the needs of power transmission or serve as a component of a transmission line, realizing the integration of multiple functions. It is widely used in power communication, smart grid, railway communication and other fields.

The device provides a composite optical cable with strong weather resistance, strong pressure resistance and shielding ability, and long life. Although the device has strong weather resistance, strong pressure resistance and shielding ability, and long life, the device has poor heat dissipation effect during the use of the optical cable, which can easily cause the optical cable temperature to be too high and affect its use, thereby causing damage to the optical cable and affecting the service life of the optical cable.

[0004] Therefore, it is necessary to design a composite optical cable that can dissipate heat for the optical cable, reduce the contact area, improve the heat dissipation effect, prevent the optical cable from being damaged due to excessive temperature, and extend the service life of the optical cable.

[0006] The technical solution is: a composite optical cable, including an optical cable core, a loose tube, an inner liner and a filling layer. The optical cable core is provided with multiple loose tubes, the outer sides of the optical cable cores are connected to the loose tubes, the outer sides of the loose tubes are connected to the inner liner, and the outer sides of the inner liner are connected to the filling layer.

[0007] Furthermore, a central reinforcement piece is also included, and the middle part of the filling layer is connected with the central reinforcement piece.

[0012] Furthermore, it also includes a reinforcing wire, and the reinforcing wire is wound inside the anti-wear layer.

[0013] Beneficial effects: 1.
