DDM (Digital Diagnostic Monitoring) inyanzvi inoshandiswa mune optical modules. Inoshandiswa kuongorora mamiriro ekushanda e optical modules. Iyo chaiyo-nguva paramende yekutarisa nzira ye optical modules. Inobvumira vashandisi kutarisa ma parameter e optical modules munguva chaiyo, kusanganisira yakagamuchirwa optical simba, transmitted optical simba, tembiricha yekushanda, magetsi emagetsi uye laser bias ikozvino. Zvadaro, enzanisa kukosha kwakatariswa nehuwandu hwehuwandu hunodiwa neoptical module pasi pemamiriro ekushanda. Kana isiri mukati mechikamu chinodiwa, alarm ichapihwa. Kana iyo optical module inoratidzwa kuve mune yakaipa mamiriro, iyochinjaichamira kutumira data, uye haizotumire kana kugamuchira data zvakare kudzamara iyo optical module iri mune yakajairika mamiriro.
Iyo optical module DDM inoshanda zvichienderana neyakajairwa parameter tsika inotsanangurwa neSFF-8472 protocol. Iyo SFF-8472 protocol inotsanangura akajairwa parameter makoshero kana marenji anofanirwa kuteverwa nesoftware uye hardware ye optical modules uye network zvishandiso (senge switch), kuve nechokwadi chekudyidzana kwezvigadzirwa zvinopihwa nevakasiyana network network vatengesi uye optical module vatengesi. Muchidimbu, seti yeakajairwa OAM paramita inogona kugovaniswa neiyo yese indasitiri yekutaurirana. Zvinokosha kucherechedza kuti kururama kwezvimwe zvigadzirwa zvakapfuura zvinodiwa nechibvumirano. Iyi tafura inotevera inoratidza iyo parameter zviyero zveSFF-8472 protocol ye optical modules.
