Abstract:
A method of fine training a micro-electromechanical mirror (MEMS) optical cross connect (OXC) system containing a plurality of input ports (Ni) and a plurality of output ports (No), the method comprising the steps of:creating a set of time-delayed input optical pulses, said set of time-delayed input optical signals having optical signals that occupy a unique, non-overlapping time slot with respect to other pulses in the set; supplying the set of time-delayed input optical signals to at least some (K) of the plurality of input ports Ni of the OXC, where K<=Ni, such that each of the K input ports receives a time-delayed input signal during a unique time slot; causing the OXC to switch the signals supplied at the K input ports to provide K output signals at the plurality of output ports No, where K<=No; receiving the switched OXC output optical signals at the K output ports; combining the K output signals to form a combined output signal; and measuring the optical energy in the combined output signal.
