Abstract
A method for optical transceiver misconnection identification that allows a simple low-level process to monitor and communicate optical transceiver characteristics information between two optical transceiver modules regardless of their transceiver type to determine if they are correctly connected or mismatched. If a mismatch is determined, the knowledge gained about the transceiver type of a far end module may be obtained (and presented to an installer) and used by an installer to select and install a module that is operationally compatible with the far end optical module.
