Title: Multistage optical switch and connecting method used therefor
Inventor: SCHROEDER DALE
IPC: H04Q11/00
Filed: 2000-08-08
Abstract: PROBLEM TO BE SOLVED: To obtain a multistage optical switch whose position-dependent loss is kept in uniform level by optically connecting the high-order output port of the switching unit of one stage to the low-order input port of the switching unit of a succeeding stage. SOLUTION: The 1st output ports I (P, 0) of the respective switching units 68, 70 and 72 of the 1st stage 62 are connected to the 5th input ports Mid (M, 4) of the intermediate switching units 74, 76 and 78. On the contrary, the respective 5th output ports I (P, 4) of the 1st stage 62 are connected to one of the 1st input ports Mid (M2, 0) of an intermediate stage 64. As a result, an optical signal is outputted from/inputted to the 1st stage through the input/output port of the same rank. When the optical signal is outputted from/inputted to the 2nd stage through the input/output port of the same rank, all the optical signals inputted to the 1st stage and outputted from the 2nd stage are maintained with the loss of the positional dependency of 8K.
