Abstract
A method in a transceiver apparatus for monitoring an optical link over which one or more data signals are to be transmitted comprises time interleaving a test signal with an auxiliary management and control channel, AMCC, signal to form a time-interleaved signal. The time-interleaved signal is transmitted with one or more downstream data signals over the optical link. A backscattered test signal is received to monitor the optical link.
