Abstract
The present disclosure relates to optical networking, namely a rapid channel plan optimization using fast tuning lasers. Fast tuning lasers, able to tune across the optical C-Band in < 10 ns, are becoming available. As such, the present disclosure explores using transceivers with fast tuning lasers and the coordination thereof to rapidly change the channel plan of a wavelength division multiplexed (WDM) system. This may be accomplished without the loss of traffic by briefly buffering data and ensuring the tuning + reacquisition occurs before the buffer overflows. An example of which is time division multiplexed (TDM) coherent passive optical networks (CPON) which attempt to achieve rapid acquisition (such as <2048 symbols target). This disclosure also explores a dual control signals scheme for fast tuning lasers, claiming the solution of using two power supplies: one low frequency control signal (LFCS) and one high frequency control signal (HFCS).
