An optical test apparatus. The test apparatus includes an optical source.
A first optical switch is connected to the optical source. An attenuated
responsivity test path may be selectively coupled to the first optical
switch. A return loss test path may alternatively be selectively coupled
to the first optical switch. A second optical switch may be selectively
coupled to the attenuated responsivity test path or the return loss test
path. An optical splitter is connected to the second optical switch. The
optical splitter is configured to connect to a ROSA. A detector is
connected to the optical splitter. The detector is configured to connect
to a test meter.
