It is a user terminal for FTTH (Fiber To The Home) solution, with reasonable interior space design. It is used at homes or in work areas for single-core or double-core fibers and port output. It can fully meet the requirement for bending radius of fibers, protect inlet/outlet of fibers, provide safe protection for fiber cores and appropriate bending radius, allow storage of a small quantity of redundant fibers, and implement application of the FTTH system.
