OPTICAL SIGNAL SWITCHING UNIT Russian patent published in 2009 - IPC G02F7/00 

FIELD: physics; optics.

SUBSTANCE: invention relates to optical data encoding, decoding and transmitting devices, in particular, to optical signal switching devices used in computer networks. Switching device comprises four logical units. Logical unit comprises inputs/outputs 1, 2, 3. The 1^st input/output of the 1^st - the 4^th logical units is input/output of the 1^st - the 4^th channels of the switching device, respectively. The 2^nd input/output of the 1^st logical unit is connected to the 2^nd input/output of the 3^rd logical unit. The 2^nd input/output of the 2^nd logical unit is connected to the 2^nd input/output of the 4^th logical unit. The 3^rd input/output of the 1^st logical unit is connected to the 1^st input/output of added 5^th logical unit. Its 2^nd input/output is connected to the 3^rd input/output of the 2^nd logical unit. The 3^rd input/output of the 4^th logical unit is connected to the 3^rd input/output of the 5^th logical unit. Its 4^th input/output is connected to the 3^rd input/output of the 3^rd logical unit.

EFFECT: simplified optical signal switching device and enhanced functional capabilities thereof.
