摘要： A simultaneous optical compression and decompression apparatus having a simple symmetrical arrangement including a plurality of optical splitting/combining units capable of achieving simultaneous splitting and combining of optical signals in opposite directions, a plurality of optical delay units each arranged between adjacent ones of the optical splitting/combining units and adapted to delay the time taken for an optical signal to pass therethrough in each of opposite directions by a predetermined time, so as to reproduce the optical signal in accordance with a predetermined rule. The apparatus also includes a pair of optical isolation units respectively connected to opposite end-side ones of the optical splitting/combining units, each of the optical isolation units being adapted to allow an optical signal to pass therethrough in one direction; a pair of optical switching units respectively connected to opposite end-side ones of the optical splitting/combining units and adapted to switch optical signals output from the optical splitting/combining units in response to control signals, so as to allow predetermined optical signals to pass therethrough; and a pair of control units respectively connected to the optical switching units and adapted to apply the control signals to the optical switching units.
