WAVELENGTH SELECTIVE SWITCH, RACK, AND OPTICAL TRANSMISSION DEVICE

원문 (중국어)

A wavelength selective switch, a rack, and an optical transmission device are disclosed. The wavelength selective switch includes an electrical interface connected to an optical cross-connector through a circuit and disposed on a first plane of a backplane. After the wavelength selective switch is installed onto the rack, the electrical interface is connected to a first electrical interface. The first electrical interface is included in the rack. An optical interface is connected to the optical cross-connector through an optical fiber. The optical interface is disposed on at least one of the first plane or a third plane. After the wavelength selective switch is installed onto the rack, the third plane is on a surface of the rack. When the wavelength selective switch is being installed onto the rack, a direction of a motion trajectory of the wavelength selective switch is perpendicular to the third plane.
