Background technique

As people's demand for information in production and life becomes larger and wider, communication technology advances by leaps and bounds, presenting a prosperous scene of information technology in the ascendant. Under the demand of widely adopting information technology in various fields, communication products that are born on demand have sprung up one after another. However, in major equipment such as aerospace, ships, offshore platforms, oil exploration, power plants and other major equipment with large temperature difference between high and low temperatures, high flame retardancy requirements, and strict communication requirements, due to the small demand for communication products, strict quality requirements, and performance factors The requirements are constantly changing due to different occasions. So far, no professional industry standards and product series have been formed in terms of high-end communication products, especially communication cable products. the

Existing marine engineering, large-scale power equipment, oil production equipment, underwater sewage discharge or monitoring systems generally use mutually independent cable systems. This type of cable usually has problems such as high cable laying cost and high difficulty factor. In order to monitor the working status of the equipment, laying monitoring cables independently not only takes up expensive equipment space, but also easily damages the previous cables when laying cables repeatedly, increasing the laying time. Difficulty, there are problems such as difficult cable installation, excessive space occupation, insufficient product reliability, and low system integration. the
