The multistage switching device contains in a first switching stage (KS1) a plurality of n/2n space couplers (RKL1 RKLx), in the middle switching stage (KS2) "m" x/x space couplers (RK11-RK1m, ...) are combined to form a switching matrix (KE1, ... KEy), in a third switching stage (KS3) a plurality of 2n/n space couplers (RKR1-RKRx) are provided and instead of canonically wired intermediate lines between the switching stages (KS1, KS2, KS3), connecting cables (VK) are provided which respectively connect interface output ports (L11-L1y, ...) of the first switching stage (KS1) to coupler input ports (E11-E1x, ...) and coupler output ports (A11-A1x) to interface input ports (R11-R1y, ...) of the third switching stage (KS3).
