A Python library to create, read and modify the 256-byte A0h page of SFP EEPROM per SFF-8472. It exposes named fields (vendor, part, serial, wavelength, bit rate, encoding, link lengths, diagnostics options), generates images from scratch or from a binary, and validates/recalculates checkssums. It…
Bench work: re-coding a small batch of SFP+ modules so they carry the vendor string and part number the customer's kit expects. The edit itself is trivial in a hex editor, the write goes through, the read back matches byte for byte what I wrote - and the host still throws the module out. generic…
I keep a shelf of pulled SFPs at home and I would like to be able to read their EEPROM, repair a module whose checksum got mangled, and occasionally recode one for a switch that is picky about vendor strings. Buying a commercial programmer for a handful of modules a year makes no sense here, so I…
