CIRCUIT CHANGER OF OPTICAL SIGNALS Russian patent published in 2009 - IPC G02B6/35 

FIELD: physics; communication.

SUBSTANCE: invention concerns to devices for coding, decoding and the 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 accordingly an inlet-exit of the first-fourth channels of the circuit changer. The fifth and sixth logic blocks contain the first-fourth inlets-exits. The second inlet-exit of the third logic block is joined to the second inlet-exit of the fifth logic block. Its third inlet-exit is joined to the second inlet-exit of the fourth logic block. The third inlets-exits of the third and fourth logic blocks are the first and second inlets-exits of expansion of the circuit changer of optical signals. The first and fourth inlets-exits of the fifth logic block are joined accordingly to the second inlets-exits of the first and second logic blocks. The third inlets-exits of the first and second logic blocks are joined to the first and fourth inlets-exits of the sixth logic block.

EFFECT: simplification of the circuit changer of optical signals and expansion of its functionality.
