Abstract: A fiber access terminal including a first assembly and a second assembly. The first assembly includes a first box body and an optical fiber adapter. The second assembly includes a second box body, an optical splitter, an optical fiber connector, and a plurality of optical fiber adapters. The optical fiber adapter of the first assembly is disposed outside the first box body. The optical splitter is disposed inside the second box body, and the optical fiber connector and the plurality of optical fiber adapters of the second assembly are disposed outside the second box body. A first end of the optical fiber connector is detachably connected to the optical fiber adapter of the first assembly, a second end of the optical fiber connector is connected to an input port of the optical splitter, and each output port is connected to one optical fiber adapter of the second assembly.

Abstract: A tunable filter includes a first waveguide body, a second waveguide body, a metal plate, a tuning piece, and a driving piece. A first cavity is disposed in the first waveguide body, and a second cavity is disposed in the second waveguide body. The metal plate is sandwiched between the first waveguide body and the second waveguide body, multiple windows are disposed on the metal plate, and the first cavity and the second cavity are in communication and are symmetrically distributed on both sides of the metal plate. The tuning piece includes a dielectric pull-rod and multiple metal sheets connected to the dielectric pull-rod, the dielectric pull-rod protrudes out of the first waveguide body and is connected to the driving piece, the multiple metal sheets are disposed inside the first cavity, and the multiple metal sheets are disposed corresponding to the multiple windows.
