OPTICAL SIGNAL SWITCHING UNIT Russian patent published in 2009 - IPC G02B6/35 

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 six logical units. Logical unit comprises inputs/outputs from the first to the sixth one. The first input/output of the1^st - the 6^th logical units is input/output of the 1^st - the 6^th channels of the switching device, respectively. The 2^nd - the 6^th inputs/outputs of the first logical unit are connected, respectively, to the 2^nd input/output of the second logical unit, to the 3^rd input/output of the sixth logical unit, to the 4^th input/output of the third logical unit, to the 5^th input/output of the fifth logical unit and to the 6^th input/output of the fourth logical unit. The 3^rd - the 6^th inputs/outputs of the second logical unit are connected, respectively, to the 3^rd input/output of the third logical unit, to the 4^th input/output of the fourth logical unit, to the 5^th input/output of the sixth logical unit and to the 6^th input/output of the fifth logical unit. The 2^nd, the 5^th and the 6^th inputs/outputs of the third logical unit are connected, respectively, to the 2^nd input/output of the fourth logical unit, to the 4^th input/output of the fifth logical unit and to the 6^th input/output of the sixth logical unit.

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