Claim 0:
1. An optical source switching apparatus comprising:
one or more first optical sources;
an optical cross-connect device;
one or more second optical sources;
a first coupler;
a second coupler;
a first optical modulator; and
a second optical modulator, wherein an input of the optical cross-connect device is connected to the one or more first optical sources, a first output of the optical cross-connect device is connected to a first input of the first coupler, a second output of the optical cross-connect device is connected to a first input of the second coupler;
a second input of the first coupler is connected to the one or more second optical sources, a second input of the second coupler is connected to the one or more second optical sources;
an output of the first coupler is connected to the first optical modulator, and an output of the second coupler is connected to the second optical modulator;
the one or more first optical sources and the one or more second optical sources are configured to output continuous optical energy;
the optical cross-connect device is configured to enable optical energy output by at least one of the one or more first optical sources to enter the first coupler and the second coupler, wherein the first coupler is configured to couple optical energy output by the one or more second optical sources or the optical cross-connect device into the first optical modulator, and the second coupler is configured to couple optical energy output by the one or more second optical sources and the optical cross-connect device into the second optical modulator; and
the first optical modulator is configured to modulate optical energy from the first coupler and the second optical modulator is configured to modulate optical energy from the second coupler.
