Title:
OPTICAL AUTODISCOVERY FOR AUTOMATED LOGICAL AND PHYSICAL CONNECTIVITY CHECK BETWEEN OPTICAL MODULES
Document Type and Number:
WIPO Patent Application WO2007005970
Kind Code:
B1
Abstract:
Optical autodiscovery is provide between two optical modules to insure that when an optical signal is coupled between the two optical module, the optical signal from a first module does not interfere with operation of a second module. The autodiscovery is implemented by sending an optical identification signal from the first optical module via the coupling to the second optical module from which signal, the second optical module can verify and determined acceptance of the coupled first optical module. During this autodiscovery process, the optical identification signal from the first optical module may be attenuated or shifted in optical spectrum so as not to interfere with the operation of the second optical module. Autodiscovery may also be employed in cases where a first optical module is to receive an optical signal from a second module.
