Example Embodiment

[0021] Examples:

[0022] Such as figure 1 , figure 2 , image 3 As shown, in this embodiment, a high mechanical strength optical cable includes an outer sheath 1, a support provided in the outer sheath 1, an inner sheath 4 provided between the outer sheath 1 and the support, and Several optical fiber protection sleeves 5 in the sheath 4 and the optical fibers 6 arranged in the optical fiber protection sleeve 5 are provided with an armor layer 3 on the outside of the inner sheath 4. By providing a support in the outer sheath 1, the outer The sheath 1 is divided into multiple areas to facilitate the installation of multiple groups of optical cables, and the support can play a role of isolation, prevent the inner sheath 4 from being entangled, and make the optical cable easy to branch. The support can also be used to support It can improve the compression and bending resistance of the present invention and the mechanical strength of the optical cable. By providing the armor layer...

Abstract

The invention discloses a high mechanical strength optical cable, comprising an outer sheath (1), a support member arranged inside the outer sheath (1), and an inner sheath (4) arranged between the outer sheath (1) and the support member , Several optical fiber protective sleeves (5) arranged in the inner sheath (4) and optical fibers (6) arranged in the optical fiber protective sleeve (5), and an armor layer ( 3). The beneficial effects of the present invention are: the present invention can divide the interior of the sheath into multiple regions by providing a support in the outer sheath, so as to facilitate the installation of multiple groups of optical cables, make the optical cables easy to branch, and can also play a supporting role, improving The compression resistance and bending resistance of the present invention improve the mechanical strength of the optical cable, and the mechanical strength of the present invention can be increased by setting the armor layer, which is beneficial to prevent the deformation of the inner sheath from compressing the optical fiber, thereby protecting the optical fiber, and It is also possible to improve the pressure resistance of the present invention.

Description

technical field [0001] The invention relates to the field of optical cables, in particular to an optical cable with high mechanical strength. Background technique [0002] Optical fiber, referred to as optical fiber, is a light transmission tool that transmits light on the principle of total reflection in fibers made of glass or plastic. The tiny fiber is encapsulated in a plastic sheath that allows it to be bent without breaking. Typically, a transmitting device at one end of the fiber uses a light-emitting diode or a laser to transmit light pulses into the fiber, and a receiving device at the other end of the fiber uses a photosensitive component to detect the pulses. Cables that contain optical fibers are called fiber optic cables. Because the transmission loss of light in optical fibers is much lower than that of electricity in wires, and because the main raw material is silicon, which has a huge reserve and is easy to mine, it is cheap, which prompts optical fibers to...
