Abstract
Methods according to the disclosure include methods for managing data flow in an optical communications system having a plurality of vertical cavity surface emitting lasers (VCSELs). The method generally includes determining whether operation of the system exceeds a thermal threshold for a thermal parameter of the system, and switching from a first data bandwidth to a second data bandwidth when the thermal threshold is exceeded. Operation at the second data bandwidth further includes determining whether further operation of the system demands the first data bandwidth, and resuming operation of the system at the first data bandwidth only when the thermal parameter during operation at the second data bandwidth does not exceed the thermal threshold.
