Abstract
An optic module is disclosed having a shared bus interface, a transmit disable line, a memory and control logic or a processor configured to facilitate address modification via a bus shared by multiple optic modules. A single housing may contain multiple modules, all of which are preferably accessible via a shared host via a shared bus. Standard compliant modules share a common address, which inhibits communication with only a particular optic module, via the shared bus, in a housing containing multiple optic modules. Using a common message to all modules to treat a transmit disable line as a module select line, a single module may be active during an address re-write operation. This process may repeat until all the modules within the housing have unique addresses.
