OPTICAL SWITCHING EQUIPMENT FOR THE THROUGH-CONNECTION OF OPTICAL MESSAGE CELLS

摘要

An optical switching network for through-connecting optical message cells has at least one optical space-switching multiple connected at its input side to the inputs thereof and has at least. one optical transit time harp formed with a plurality of light waveguides with graduated transit times of whole-number, n- multiples (with n ~ 0) of the message cell duration. The outputs of a transit time harp following a space-switching multiple are respectively combined to a concentrator output of the optical switching network.
