FIELD: physics; communication. ^ SUBSTANCE: invention concerns to devices for coding, decoding and data transmission, presented by optical signals, in particular, to the circuit changers of optical signals applied in computer networks. The circuit changer contains four logic blocks, the logic block contains the first-third inlets-exits, the first inlet-exit of the first-fourth logic blocks is the an inlet-exit of the first-fourth channels of the circuit changer. The fifth and sixth logic blocks are in addition entered into the circuit changer. ^ EFFECT: simplification of the circuit changer of optical signals and expansion of its functionality. ^ 2 cl, 14 dwg |
