With the rapid development of 5G technology

the rapid construction and expansion of communication room

the number and power of equipment in the room increase sharply. There are some shortcomings in traditional electronic temperature measurement methods

such as limited number of temperature measurement points

complex laying transmission cables

and unfavorable maintenance and management.Aiming at the difficult problem of temperature monitoring for such communication equipment

a distributed optical ? ber temperature measurement method based on Raman scattering and time domain re? ection is proposed. It can effectively improve the spatial resolution of temperature measurement and reduce the difficulty of system laying. It can provide high quality temperature data for the computer room efficiency analysis and dynamic simulation platform. The feasibility of the system is verified by experimental application

and it can provide design reference for the follow-up energy-efficient construction planning of communication computer room.
