Digital Diagnostic Memory Memo (Inoenderana neSFF-8472)

Iwo ma-transceivers anopa serial ID memory yemukati uye yekuongorora ruzivo nezve iripo yekushanda mamiriro neiyo 2-waya serial interface (SCL, SDA).

Irwo ruzivo rwekuongorora nemukati calibration kana yekunze calibration zvese zvinoitwa, kusanganisira yakagashirwa magetsi ekutarisa, inofambiswa magetsi ekutarisa, bias ikozvino yekutarisa, yekugovera voltage yekutarisa uye tembiricha yekutarisa.

Iyo yedhijitari yekuongorora mepu yemepu yedata data inotsanangura seinotevera (Kuti uwane rumwe ruzivo, ndapota tarisa kune SFF-8472).
