Abstract:
A CO comprises a plurality of IM lasers and a Butler matrix system coupled to the plurality of IM lasers. The Butler matrix system comprises a plurality of optical input ports corresponding to the plurality of IM lasers, Butler matrix components coupled to the plurality of optical input ports, and a plurality of optical output ports coupled to the Butler matrix components and corresponding to the plurality of optical input ports. A method comprises generating an optical signal; receiving an analog electrical signal; modulating the analog electrical signal onto the optical signal using IM to create a modulated optical signal; and introducing, using a Butler matrix system, a phase shift to the modulated optical signal to create a phase-shifted modulated optical signal.

Claim (Index 16):
A central office (CO) comprising:\n a Butler matrix system configured to:\n receive an intensity-modulated (IM) optical signal, and \n phase shift the IM optical signal to create a phase-shifted modulated optical signal; and \n an optical switch coupled to the Butler matrix system, comprising an input port and an output port, and configured to direct the shifted optical signal from the input port of the optical switch to the output port of the optical switch.
