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 operates purely on data and does not talk to hardware.

  • Transceivers: SFP, SFP+, SFP28, QSFP variants
  • Form factor: SFP, SFP+

Accepted answer

Use the library to author or edit the A0h fields and let it compute the checksums, then export the 256-byte binary for flashing with separate hardware.
