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 seven logic blocks, the logic block contains the first-seventh inlets-exits, the first inlet-exit of the first-seventh logic blocks is accordingly an inlet-exit of the first-seventh channels of the circuit changer, the first-sixth logic blocks in addition contain the eighth inlet-exit, the second-eighth inlets-exits of the first logic block are joined accordingly to the second inlet-exit of the second logic block, with the third inlet-exit of the seventh logic block, with the fifth inlet-exit of the third logic block, with the fifth inlet-exit of the sixth logic block, with the seventh inlet-exit of the fourth logic block, with the seventh inlet-exit of the fifth logic block and with the eighth inlet-exit of the second logic block, the third-seventh inlets-exits of the second logic block are joined according to the third inlet-exit of the third logic block, to the fourth inlet-exit of the fourth logic block, with the fifth inlet-exit of the seventh logic block, with the sixth inlet-exit of the fifth logic block and with the seventh inlet-exit of the sixth logic block. ^ EFFECT: simplification of the circuit changer of optical signals and expansion of its functionality. ^ 2 cl, 13 dwg |
