Abstract
A system and method for transmitting an optical signal. The system includes a first optical transmitter capable of transmitting a first optical signal under one or more first operating conditions, and the first optical signal corresponds to a first wavelength. Additionally, the system includes a second optical transmitter capable of transmitting a second optical signal under one or more second operating conditions, and the second optical signal corresponds to a second wavelength. Moreover, the system includes an optical multiplexer coupled to the first optical transmitter and the second optical transmitter and capable of generating a multiplexed optical signal, a detection component configured to determine at least whether the first optical transmitter satisfies one or more predetermined conditions, and a tunable optical transmitter capable of transmitting a third optical signal. The third optical signal corresponds to a third wavelength.
