Patent ID: 7720329

Claim:
An optical system, comprising: at least one first moveable mirror for receiving and reflecting at least one first selected wavelength from one or more input fiber ports to one output fiber port according to a position of said first mirror, said output fiber port transmitting an output optical signal of selected wavelengths from one or more input optical signals from said one or more input fiber ports; a tap for coupling a portion of said output fiber port output optical signal to a first monitoring port; at least one second moveable mirror for receiving and selectively reflecting at least one second selected wavelength from said first monitoring port to an output monitoring port according to a position of said second mirror; at least one steering element for steering the first selected wavelength from each of said one or more input fiber ports onto said first mirror, and steering the first selected wavelength from said first mirror to said output fiber port, and further steering the second selected wavelength from said first monitoring port onto said second mirror, and steering the second selected wavelength from said second mirror to said output monitoring port; and an optical measurement device for receiving the second selected wavelength of a portion of the output optical signal coupled to said output monitoring port and measuring at least one optical property of the output optical signal.
