Abstract:
1. An optical switching equipment for switching a route of an optical signal received from any one of a plurality of optical transmission routes and outputting said optical signal to any one of a plurality of optical transmission routes, comprising: first interfaces for transmitting or receiving optical signals to or from other optical switching equipment through a plurality of first optical transmission routes; second interfaces for transmitting or receiving optical signals to or from a communicating equipment connected to said optical switching equipment through a plurality of second optical transmission routes; at least one optical switch for providing routes of optical signals between interfaces; and a control circuit for setting the route of each the optical signals inside said at least one optical switch; wherein: each of said second interfaces includes means for splitting a signal received from a second optical transmission route into a plurality of optical signals for output to said optical switch, and means for selecting one of a plurality of optical signals received from said optical switch for output as a selected signal to a second optical transmission route, said control circuit sets a route between first interfaces in said at least one optical switch, and said control circuit sets in said at least one optical switch at least one of:
