• 1. Introduction Optical fiber sensing takes advantage of the physical properties of light as it passes through the optical fiber to detect changes in temperature, strain and other parameters. Optical fiber has wide working frequency band and large dynamic range, which is suitable for remote measurement and remote control. It is an excellent low loss transmission line. Under certain conditions, optical fiber is particularly easy to accept the measured or field loading, and is an excellent sensing element. The optical fiber is electrically neutral, small in size, light in weight, flexible, anti electromagnetic interference, and good in radiation resistance. It is especially suitable for use in flammable, explosive, space restricted, strong electromagnetic interference and othe...

    Cloud data center is the infrastructure of cloud computing. Cloud computing business is continuing to penetrate, driving the construction of cloud computing super data center. The cloud IT infrastructure is mainly composed of switches, servers, and optical cables and optical modules (or AOC) that interconnect all these. The large-scale cloud data center will greatly increase the use of optical modules, and have more requirements for the transmission distance of optical modules, which will increase the proportion of single-mode optical modules.The explosive growth of cloud data center traf...

    With the rapid development of science and technology, we have entered the information age. All over the world, people use computers for work and mobile phones for entertainment to upload and download data all the time. These data contain a lot of information, and most of which should be gathered in the data center, exchanged and processed through the switch, or uploaded to the server for backup storage. In order to prevent the information of individuals, enterprises and governments circulating on the network and stored on the server from being leaked or even stolen, server and networ...
