Title: WAVELENGTH SELECTION SWITCH APPARATUS, COMMUNICATION DEVICE AND WAVELENGTH SWITCHING METHOD
Abstract:
A wavelength selection switch apparatus, a communication device and a wavelength switching method. The wavelength selection switch apparatus comprises an incident/outgoing unit (10), a wavelength dispersion/synthesis unit (20), a light beam focusing unit (30), a first light beam deflection unit (40), an optical path conversion unit (50) and a second light beam deflection unit (60). The incident/outgoing unit (10) comprises M incident ports and N outgoing ports. The first light beam deflection unit (40) comprises M incident sub-blocks corresponding to M incident ports on a one-to-one basis, the second light beam deflection unit (60) comprises N outgoing sub-blocks corresponding to N outgoing ports on a one-to-one basis, and each incident sub-block and each outgoing sub-block respectively comprises a plurality of deflection regions respectively corresponding to a plurality of wavelengths.
