A quality inspection process for quantum secure communication transmission optical fiber

Abstract

The invention belongs to the technical field of optical fiber quality testing, and particularly relates to a quality testing technology for quantum secure communication transmission optical fibers. The technology comprises the following steps that the produced optical fibers are sampled, and a sample to be detected is selected out; the optical fibers which are not subjected to any external pressure are tested through related testing tools; multi-angle pressurization is carried out on the optical fibers through a mold special for multi-angle pressure testing of the quantum secure communicationtransmission optical fibers, and then the optical fibers are correspondingly tested by using the related testing tools; and contrastive analysis is carried out on test data when the optical fibers arenot pressed and when the optical fibers are subjected to multi-angle pressurization, and whether the quality of the optical fibers is qualified or not is judged. According to the technology, whetherthe quality of the optical fibers is qualified or not can be rapidly tested, meanwhile, the test data has high persuasiveness, and the technology is suitable for quality testing of the high-performance optical fibers.

Description

technical field [0001] The invention belongs to the technical field of optical fiber quality inspection, and specifically relates to a quality inspection process of optical fiber for quantum secret communication transmission. Background technique [0002] In today's society, people's information transmission mode has gone beyond the stage of cable plus twisted pair, and now people generally use optical fiber to transmit data information. Optical fiber communication has a large transmission capacity and fast transmission speed, so it is very popular among people. However, with the development of information technology, people have higher and higher requirements for communication quality and communication security. Quantum communication is also gradually appearing in our sight. Quantum mechanics The uncertainty principle and quantum non-cloning principle make quantum communication absolutely safe, so that people's communication security is guaranteed. At present, quantum commu...

Optical fiber communication has a large transmission capacity and fast transmission speed, so it is very popular among people. However, with the development of information technology, people have higher and higher requirements for communication quality and communication security. Quantum communication is also gradually appearing in our sight. Quantum mechanics The uncertainty principle and quantum non-cloning principle make quantum communication absolutely safe, so that people's communication security is guaranteed. At present, quantum communication is also transmitted through optical fibers. The quality of quantum communication has a great relationship with the quality of optical fibers. The traditional quality inspection process cannot detect the impact of optical fiber performance when the optical fiber is subjected to different angles of pressure in nature, and cannot guarantee that the produced optical fiber can still be used normally when it is subjected to natural pressure. This has become a factor affecting the production of quantum secure communication optical fibers. a puzzle
