The "personality" for these modules is stored in a bog standard 3.3V 256 byte I2C EEPROM (address 0xA0). The I2C bus is n the connector. An Arduino can reprogram that memory. For the simplest case you just change the vendor ID info. I think the kilobuck level programmers is just a simple I2C interface with some software that knows what to change.
-------------- >As far as the reprogramming goes (another comment on the list) - I understand that is to make the unit have some particular flavor SFP-wise. If you were plugging them into a Cisco switch and all you had was ones configured for Juniper switches, then you'd want to do that. At the multikilobuck level to do this, you'd need a LOT of them to make it worthwhile. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
