Method for producing long-distance transmission optical cable made of manganese and cupronickel special alloy

Abstract

The invention provides a method for producing long-distance transmission optical cables made of manganese and cupronickel special alloy. A preformed rod made of the manganese and cupronickel special alloy is subjected to high-speed wiredrawing and becomes a fiber core of an optical fiber. The fiber core is subjected to coating and cladding to obtain the optical fiber with the depletion rate of less than 3dB / km. The optical fiber with the depletion rate of less than 3dB / km reaches the international leading level of the manganese and cupronickel alloy optical fiber. The optical cable made of the manganese and cupronickel special alloy is an insulator material, has strong immunity on electromagnetic interference in the process of transmitting signals, and is free from natural thunder interference and interference of artificially released electromagnetism. Moreover, the optical cable made of the manganese and cupronickel special alloy is thin in wire diameter, light in weight, flexible, small in occupied space, little in pollution, high in electrical conductivity, corrosion-resistant, heat-resistant, simple in technological process, long in service life and wide in application range. Therefore, products developed through adoption of the method not only can be applied to main communication lines, but also can be applied to an electric power telecommunication control system for industrial monitoring and control. The application range of the optical cables is substantially expanded.

Description

technical field [0001] The invention relates to a production method of a digital optical fiber cable, in particular to a production method of a digital optical fiber cable for long-distance transmission of a special alloy of manganese and white copper. Background technique [0002] At present, the common digital optical fiber cables in the power communication industry mostly use pure silica cores, and silica glass optical fibers are used as optical transmission media for long-distance and large-capacity public networks due to their advantages such as low attenuation and high bandwidth. Due to the high purity of raw materials, complex manufacturing, resistance to bending and extrusion, and difficulty in continuous operation, quartz glass optical fibers limit the advantages of low-voltage power cable composites, and restrict their extensive use as composite transmission media for short-distance optical fiber access. .

Problems solved by technology

Due to the high purity of raw materials, complex manufacturing, resistance to bending and extrusion, and difficulty in continuous operation, quartz glass optical fibers limit the advantages of low-voltage power cable composites, and restrict their extensive use as composite transmission media for short-distance optical fiber access.

In the current market and in the planning and design of communication networks, regardless of the communication distance and broadband requirements, special quartz optical fibers are generally used to transmit optical signals, resulting in high communication costs and excessive costs for short distances.
