Optical switch plays a very important role in optical network. In
WDM transmission system, optical switch can be used for wavelength
adaptation, regeneration and clock extraction. In OTDM system,
optical switch can be used for demultiplexing. In all-optical
switching system, optical switch is optical cross connect, OXC) is
the key device of wavelength conversion. According to the number of
input and output ports of optical switch, it can be divided into 1
× 1, 1 × 2, 1 × n, 2 × 2, 2 × n, m × N and so on. They have
different uses in different occasions.
JHBF OSW are widely used in the field of optical communication.
