I-DDM (i-Digital Diagnostic Monitoring) iteknoloji esetyenziswa kwiimodyuli ze-optical. Isetyenziselwa ukuxilonga imeko yokusebenza yeemodyuli ze-optical. Lixesha lokwenyani iparameter esweni iindlela zeemodyuli zamehlo. Ivumela abasebenzisi ukuba babeke iliso kwiiparitha zeemodyuli ze-optical ngexesha langempela, kubandakanywa amandla optical afunyenweyo, amandla okukhanya adlulisiweyo, ukushisa okusebenzayo, umbane wombane kunye ne-laser bias current. Emva koko, thelekisa ixabiso elisweni kunye noluhlu lwexabiso olufunwa yimodyuli ye-optical phantsi kweemeko eziqhelekileyo zokusebenza. Ukuba akukho phakathi koluhlu olufunekayo, i-alam iya kunikwa. Ukuba imodyuli ye-optical iboniswa ukuba ikwimeko embi, itshintshaizakuyeka ukuthumela idatha, kwaye ayizukuthumela okanye yamkele idata kwakhona de umnqongo wokukhanya ukwimeko eqhelekileyo.
Imodyuli ye-Optical i-DDM isebenza ngokusekelwe kumaxabiso eparamitha asemgangathweni achazwe yi-SFF-8472 protocol. I-protocol ye-SFF-8472 ichaza amaxabiso eparameter asemgangathweni okanye uluhlu oluza kulandelwa yi-software kunye ne-hardware yeemodyuli ze-optical kunye nezixhobo zenethiwekhi (ezifana nokutshintsha), ukuqinisekisa ukusebenzisana kweemveliso ezibonelelwa ngababoneleli bezixhobo zenethiwekhi ezahlukeneyo kunye nababoneleli bemodyuli ye-optical. Ngamafutshane, isethi yeeparamitha ze-OAM eziqhelekileyo zingabelwana ngayo yonke imboni yonxibelelwano. Kuyafaneleka ukuba uqaphele ukuba ukuchaneka kwezinye iimveliso kudlule iimfuno zesivumelwano. Itheyibhile ilandelayo ibonisa imigangatho yeparameter ye-SFF-8472 protocol yeemodyuli ze-optical.
