The Application Research of Passive Coarse Wavelength Division in 5G Indoor Distribution Prequel Bearing
Aiming at the large number of optical fiber cores required for the scale deployment of 5G rooms,this paper innovatively proposes three schemes of 5G forward transmission,namely passive coarse wavelength division multiplexing,optical fiber direct connection and source cascade,and compares and analyzes the schemes from the aspects of resource occupation,security and so on.Subdivide buildings,subways,campuses and other rooms into scenes,and put forward passive coarse wavelength division construction schemes in different scenes through comprehensive analysis.Combined with the actual engineering situation,some suggestions on the setting and installation of passive coarse wave splitter are put forward.This study is helpful to solve the practical application problem of building more optical cables with multiple cores under the scale deployment of 5G rooms,and achieve the purpose of saving optical fibers and reducing costs.
