Hey,

I do reprogram transceivers from time to time, and sometimes they require a password to be reprogrammed.

I'll just list all the passwords I have bruteforced here, feel free to let me know if you have other passwords available

Innolight TR-FC13T-NAZ0x00 0x00 0x10 0x11 (default QSFP password)@NablaSquaredG


BTW if you have transceivers you would like to have reprogrammed (but do not have the password), let me know, I can put them in the programmer and try to brute force the password

Any clue on Juniper Networks 740-021308 Rev 01 10GE SFP+ ?
I am about to receive a module so I can access the i2c bus and try myself, but I would be happy to send you one :)

It identified as a finisar module, so with a little(!) help from the Jamie's Hack Shack video I reprogrammed my Juniper SFP+ device and it happily now plays Quake 3 Arena over my 10Gb link :)
9B B0 3D FA was the magic number :D
