Fiber Optic Outdoor Cabinet is used for cable connection between optical cable and optical communication equipment. Through the adapter in the outdoor cabinet, the optical signal is led out with optical jumper to realize the optical wiring function. It is suitable for the protective connection of optical cables and distribution pigtails, and also suitable for the use of optical fiber terminal points in the optical fiber access network. Its connector plugging and unplugging durability life>1000 times. The entire curvature radius is controlled to ensure that the curvature radius of the optical fiber at any position is greater than 30mm, and each optical fiber is clearly marked, thereby avoiding the confusion that may be caused by disassembly during the maintenance process.
