<p>The present invention relates to an optical signal distribution device. An optical distribution device (10) in an embodiment includes: a first 1×2 electro-optical switch (20a), adapted to receive a first voltage control signal; a second 1×2 electro-optical switch (20b), having an input port coupled to a first output port of the first switch, and adapted to receive a second voltage control signal; a third 1×2 electro-optical switch (20c), having an input port coupled to a second output port of the first switch, and adapted to receive a third voltage control signal; and a controller (30), configured to generate the first voltage control signal, the second voltage control signal, and the third voltage control signal according to expected outputs of the second switch and the third switch. The controller is capable of selecting any combination of the outputs of the second switch and the third switch, so as to flexibly meet service requirements of an optical access network.</p> |
