Embodiment

[0032] like figure 1 As shown, a compression-resistant optical cable with torsion performance, with a circular cross-section, includes a skeleton 1, an optical fiber bundle 2, a support member 3 and a sheath 4;

[0033] The skeleton is fan-shaped, with a plurality of blades 11 in the circumferential direction, an axial through hole 12 in the center, and a limit groove 13 is formed between adjacent blades inwardly recessed. The number of blades is the same as the number of supporting parts. If the number of blades is too large, the limit slot will become smaller, which will weaken the supporting effect of the skeleton on the supporting parts. If the number of blades is too small, the compressive effect of the skeleton will not be good. Usually, the number of blades is set at 4-8. In this embodiment, the blade The number is set to 5.

[0034] The optical fiber bundle is formed by combining multiple optical fibers or twisting multiple optical fibers around the central reinforcin...

Abstract

The invention discloses a compression-resistant optical cable with distortion performance, which comprises a framework, an optical fiber bundle, a supporting component and a sheath, and is characterized in that the framework is provided with a plurality of blades in the circumferential direction, and the center is provided with an axial through hole; the optical fiber bundle is axially arranged in the through hole; the supporting component is composed of a connecting part, a first support and a second support, is in an inverted U shape and is evenly distributed on the periphery of the framework, the outer wall of the connecting part is attached to the inner wall of the sheath, and the two ends of the connecting part are connected with the first support and the second support respectively. The inner end of the first support is adaptively inserted into the limiting groove, and the inner end of the second support is embedded into the fixing groove in the right side. And the sheath is extruded on the outer surface of the supporting part. According to the optical cable, the compression resistance effect is maintained, meanwhile, the distortion performance of the optical cable is considered, wiring is convenient, the transmission capacity is large, meanwhile, the optical cable can be converted into a photoelectric hybrid cable, repeated wiring is avoided, and time and space are saved.

Description

technical field [0001] The invention belongs to the field of cables, and in particular relates to a compression-resistant optical cable with twist performance. Background technique [0002] Optical fiber cable is a medium for transmitting optical signals with optical fiber or optical fiber bundle as the cable core and outer extruded sheath. With the rapid development of the Internet, optical cable has now become the most important carrier of signal transmission. In order to improve the compressive performance of the optical cable, the mainstream method is to wind the metal tape outside the cable core, and the winding of the metal tape makes the anti-twist performance of the optical cable also taken into account, such as GYTA and GYTS layered stranded optical cables, but this kind of The disadvantage of the product is the heavy weight and high cost, which is not conducive to overhead use. [0003] In order to reduce the weight and cost of the optical cable, CN112037979A dis...
