One of optical packets x copied by an optical copying mechanism 11 is converted into an electric packet by an optic/electric converting mechanism 13 . An address information extracting mechanism 14 extracts address information from a header of the packet converted into the electric packet. A control light generating mechanism 15 generates a control light based on the extracted address information. The other of the copied optical packets x is delayed by an optical delaying mechanism 12 for a predetermined time, and entered to a third nonlinear optical effect device 1 b. The third nonlinear optical effect device 1 b switches a route of the optical packet x based on the control light. The optical packet x is outputted through an optic/electric converting mechanism 1 h 0 , a buffer 1 i 0 , a multiplexing mechanism 1 j, and an electric/optic converting mechanism 1 k.
