Abstract: The present disclosure relates to the field of communications technologies, and in particular, to an optical add/drop multiplexer, such that the optical add/drop multiplexer can ensure proper processing of light in two directions. The optical add/drop multiplexer can complete an extraction of a signal in one direction using one microring resonant cavity and two optical circulators, and if a wavelength of a signal in the other direction is the same as a resonant wavelength of the microring resonant cavity, the signal may reenter an optical network after passing through two microring resonant cavities and one optical circulator, and is not affected. Therefore, proper processing of optical signals in the two directions is ensured, and the optical signals in the two directions do not interfere with each other.

Abstract: An optical transmitting apparatus is disclosed, in the apparatus, an array light source include M*N light sources, and an included angle between any column of light sources in the N columns of light sources and any row of light sources in the M rows of light sources is a preset angle. The array light source is located on a first side of a collimating lens, a plane on which the array light source is located is perpendicular to an optical axis of the collimating lens, and a distance between the plane on which the array light source is located and a center point of the collimating lens is a focal length of the collimating lens. An rotatable scanning mirror is located on a second side of the collimating lens, and a center point of a reflective surface of the scanning mirror is on the optical axis of the collimating lens.
