Abstract:
In order to improve the reliability of a reconfigurable optical add/drop multiplexing (ROADM) device, provided is an optical add/drop device that comprises the following: a first wavelength selection unit and a second wavelength selection unit that can select and output an optical signal of a prescribed wavelength from among inputted optical signals; a first branching unit that selectively outputs a first signal being an optical signal that has been inputted from a first terminal station on a main route to the first wavelength selection unit and the second wavelength selection unit; a second branching unit that selectively outputs a second signal being an optical signal that has been inputted from a second terminal station on a sub-route to the first wavelength selection unit and the second wavelength selection unit; and a first output unit that can selectively output to the second terminal station, as a third signal, either the optical signal outputted by the first wavelength selection unit on the basis of the first signal and the second signal, or the optical signal outputted by the second wavelength selection unit on the basis of the first signal and the second signal.

Claim (Index 10):
An optical add/drop method comprising:\n selecting and outputting an optical signal of a predetermined wavelength from an input optical signal by a first wavelength selector; selecting and outputting an optical signal of a predetermined wavelength from an input optical signal by a second wavelength selector; selectively outputting a first signal being an optical signal input from a first terminal station on a main route, to the first wavelength selector and the second wavelength selector; selectively outputting a second signal being an optical signal input from a second terminal station on a sub-route, to the first wavelength selector and the second wavelength selector; and selectively outputting, to the second terminal station, one of an optical signal to be output from the first wavelength selector, based on the first signal and the second signal, and an optical signal to be output from the second wavelength selector, based on the first signal and the second signal, as a third signal.
