Abstract
Methods of operating an optical circuit switch and optical circuit switches are disclosed. A command to make an optical connection between a first port and a second port may be received. A determination whether or not input signal light is present at the first port may be made. When light is present at the first port, an optical connection may be made between the first port and the second port. When light is not present at the first port, the optical circuit switch may wait until light is present at the first port before making the connection.
