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 eight logical units. Logical unit comprises inputs/outputs from the 1^st to the 8^th. The 1^st input/output of logical units from 1 to 8 is, respectively, input/output of the 1^st - the 8^th channels of the switching device. Logical units from 2 to 4 and from 6 to 8 comprise additional 9^th input/output. Inputs/outputs 2-8 of the first logical unit are connected, respectively, to the 2^nd input/output of the second logical unit and to inputs/outputs 3, 4, 5, 6, 7, 8 of the fifth logical unit. Inputs/outputs 3-9 of the second logical unit are connected, respectively, to inputs/outputs 3, 4, 5, 6, 7, 8, 9 of the sixth logical unit.

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