Abstract
The present invention is directed to a method of synchronizing data transmission through optical links between first and second communications components. Each of the first and second communications components include an optical laser for transmitting and receiving laser signals to and from each other through the optical links. In an embodiment, the method comprises the steps of: (a) initializing each of the first and second communications components; (b) enabling the optical lasers and optical sensors; (c) exchanging idle packets between the first and second communications components to establish a datapath across the optical links; (d) exchanging test data packets across the datapath established in step (c) to verify connection of the optical links; and (e) upon verification of connection of said optical links in step (d), enabling data flow between said first and second communications components. In particular, this method is applicable to synchronizing data transmission across a parallel optical link comprising a plurality of parallel links.
