Large-core-number optical cable for pipelines

Abstract

The invention belongs to the technical field of communication optical cables, and relates to a large-core-number optical cable for pipelines. 2-6 optical cable sub-units and a same number of optical cable temperature-measuring sensing units are arranged around a central transmission unit in an alternate manner to form a cable core with a circular section in an SZ twisted manner. In a multi-layer superposed twisted optical fiber ribbon group of the optical cable sub-unit, each layer is an optical fiber ribbon, each optical fiber ribbon comprises 4-24 optical fiber cores, the optical fiber ribbon layer number and the optical fiber core number included by each optical fiber ribbon are the same, the optical fiber core number included by each optical cable sub-unit is 16-core to the minimum and 576-core to the maximum, and the total optical fiber core number of the formed large-core-number optical cable for the pipeline is 33-core to the minimum and 3457-core to the maximum. According to the optical cable, on the premise of guaranteeing that the external diameter of the optical cable is not greater than the external diameter of the conventional pipeline optical cable, the requirement of large core number is satisfied, the requirement that the central transmission unit reliably transmits center network information is guaranteed, and the optical cable is applicable to a pipeline communication laying system with large optical fiber capacity demand and difficult laying.

Description

technical field [0001] The invention belongs to the technical field of communication optical cables, in particular to a large-core optical cable for pipelines. Background technique [0002] With the accelerated integration of new-generation information technologies represented by mobile Internet, Internet of Things, cloud computing, big data, and artificial intelligence with traditional industries, higher requirements are placed on the capacity and reliability of the Internet. The current use of communication optical cables has problems in terms of external impact resistance, bending, and water resistance, which lead to serious security threats while improving network performance. Due to the high-speed characteristics of optical network data transmission, the network is very short-lived. All attacks may lead to a large amount of data error or leakage. In addition, the capacity of the existing optical cables cannot meet the demand. According to the current situation, while i...

The current use of communication optical cables has problems in terms of external impact resistance, bending, and water resistance, which lead to serious security threats while improving network performance. Due to the high-speed characteristics of optical network data transmission, the network is very short-lived. All attacks may lead to a large amount of data error or leakage

In addition, the capacity of the existing optical cables cannot meet the demand. According to the current situation, while increasing the capacity of the optical fiber, the outer diameter of the optical cable needs to be increased. It is almost more difficult to dig a new pipeline in the city than to reach the sky. However, it is now Some pipelines cannot be expanded, and the optical fiber capacity can only be increased under the condition that the outer diameter of the optical cable used in the existing pipeline remains unchanged.
