It is used in routing switchwavelength choice optical cross connection natural repair protection and so on.

Optical switch is chiefly used in OXC (optical Cross Connection) system in optical network. It can fulfill many functions such as routing, selecting optical wavelength and OXC etc.
Optical switch based on MOEMS technology obviously has more advantages than optical switch base on other technologies, such as wavelength transparence and polarize independence.
