ABSTRACT:
Systems and methods for validating a data link between two communication modules, such as optical transceiver modules configured for bidirectional optical communication, are disclosed. In one embodiment a method according to the invention includes a first optical transceiver module transmitting a first validation optical signal to a second optical transceiver module via an optical waveguide, such as an optical fiber, that physically interconnects both transceivers. The first validation optical signal is received by the second optical transceiver module, which lights an indicator light on its housing and returns a second validation optical signal to the first optical transceiver module. Upon receipt of the signal, the first transceiver lights its indicator light and enables data transfer to occur between both transceivers. In other embodiments, the validation signals can be encrypted or scrambled to authenticate the transceivers as legitimate devices, or can contain identifying or descriptive information regarding the transceivers.
