Abstract
The present invention discloses an optical switching apparatus, an optical cross-connect node, and an optical signal switching method. The optical switching apparatus includes: N input ports, N OAM modulators in a one-to-one correspondence with the N input ports, an OAM splitter, and M output ports, where the M output ports are in a one-to-one correspondence with M OAM modes; a first input port of the input ports is configured to input a first optical signal, a target output port of the first optical signal is a first output port; a first OAM modulator corresponding to the first input port modulates the first optical signal into an optical signal of a first OAM mode corresponding to the first output port; the OAM splitter transmits, to the first output port, the first optical signal received from the first OAM modulator; and the first output port outputs the first optical signal.
