The present invention provides a receiving device and an optical switching fabric apparatus, where the receiving device includes: multiple selecting modules, a fast optical switch connecting to each selecting module, an output module connecting to all the fast optical switches, and a receiver connecting to the output module, where the selecting module is configured to receive a multiwavelength optical signal, select and filter a first optical signal of a preset time segment in the multiwavelength optical signal, and send the first optical signal to the fast optical switch; the fast optical switch is configured to select a second optical signal from the first optical signal filtered by the selecting module, and send the second optical signal to the output module; the output module is configured to combine optical signals separately selected by all the fast optical switches into one optical burst signal, and send the optical burst signal to the receiver; and the receiver is configured to perform optical-to-electrical conversion on the optical burst signal, and extract service data from an electrical signal. An optical switching fabric apparatus that includes the foregoing receiving device can solve a problem in the prior art that a capacity of an optical switching matrix is small or a switching speed cannot meet a requirement. |
