Abstract
Methods according to the disclosure include methods for controlling an optical communications system. The method may include adjusting a VCSEL transmitter of the optical communications system to operate at a second data bandwidth distinct from its first data bandwidth; reducing a data flow rate of a receiver during operation of the optical communications system at the second data bandwidth; determining whether a system quality metric for the receiver meets a specification requirement; in response to determining the system quality metric does not meet the specification requirement, adjusting an operational setting of the VCSEL transmitter or the receiver; in response to determining the system quality metric meets the specification requirement, continuing operation of the optical communications system at the second data bandwidth; and in response to receiving an override signal, resuming operation of the optical communications system at the first data bandwidth.
