[0002] The basic structure of an optical cable is generally composed of a cable core, reinforcing steel wire, sheath and loose tube. At present, the structure of the butterfly optical cable causes the compressive performance of the ribbon optical cable to be poor. After being subjected to force, it is easy to produce large optical fiber attenuation, resulting in reduced transmission performance. In order to improve the performance of the ribbon optical cable, it is necessary to ensure the quality of the loose tube in the optical cable.

[0003] During the processing of outdoor butterfly optical cables, loose tube detection plays a key role in the manufacturing process of butterfly optical cables. It can discover problems in the production process, such as equipment status, and help prevent the performance degradation of optical cables during use due to loose tube problems. It also avoids the expansion and contraction of loose tubes when the temperature changes, which affects the performance of optical fibers. Therefore, optimizing extruded loose tubes is of great significance to improving the performance and quality of butterfly optical cables.

[0004] A Chinese patent with publication number CN115468739B discloses a processing method and system for a highly integrated ribbon optical cable, which obtains multiple loose tube thickness parameters, multiple fullness parameters and multiple gap parameters in the target optical cable, obtains loose tube data analysis results based on the multiple loose tube thickness parameters and multiple fullness parameters, and inputs them into a loose tube quality analysis module to obtain a loose tube quality analysis result. Similarly, a sheath quality analysis result is obtained based on the sheath quality analysis module.

[0005] In the prior art, the parameters of the loose tube and the sheath in the optical cable are analyzed, and an optical cable processing evaluation space is constructed to generate a processing evaluation result of a target optical cable. The target optical cable processing evaluation result is obtained based on the optical cable processing evaluation space, and the processing adjustment of the target optical cable is performed. However, no specific adjustment process for unqualified loose tubes is given, and the degree of influence of unqualified loose tubes on the target optical cable is analyzed. There is no pressure adjustment for extruded loose tubes, and an adjustment coefficient is provided for extruded loose tube equipment, which optimizes the pressure parameters when extruding loose tubes and reduces the performance stability of optical cables caused by loose tube manufacturing defects.

The method for processing an outdoor butterfly optical cable according to claim 5, characterized in that: In step 4, the target optical cable stability value is obtained by: In the target optical cable, the influence number ratio of unqualified loose tubes and the influence range ratio of unqualified loose tubes are obtained, and the influence number ratio of unqualified loose tubes and the influence range ratio of unqualified loose tubes are added and summed to obtain the stability value of the target optical cable.

7. The method for processing an outdoor butterfly optical cable according to claim 6, characterized in that: In step 4, the method for obtaining the ratio of the number of unqualified loose tubes is as follows: Obtain the distance between the unqualified loose tube and the qualified loose tube, and mark it as the positive difference spacing value; The positive difference spacing value is compared with the positive difference spacing threshold. The comparison process is as follows: If the positive difference spacing value is less than the positive difference spacing threshold, the qualified loose casing is marked as an abnormal loose casing; The number of abnormal loose tubes is obtained, and the ratio of the number of abnormal loose tubes to the number of loose tubes is calculated to obtain the ratio of the number of unqualified loose tubes.

8. The method for processing an outdoor butterfly optical cable according to claim 6, characterized in that: In step 4, the method for obtaining the influence range ratio of unqualified loose tube is as follows: The cross-sectional area of ​​the abnormal loose tube is obtained, and the cross-sectional areas of all the abnormal loose tubes are added together to obtain the total area of ​​the abnormal loose tubes. The ratio of the total area of ​​the abnormal loose tubes to the cross-sectional area of ​​the target optical cable is calculated to obtain the influence range ratio of the unqualified loose tubes.

9. An outdoor butterfly optical cable, characterized in that: The outdoor butterfly optical cable is prepared by the processing method described in any one of claims 1 to 8.
