DDM (Digital Diagnostic Monitoring) ni tekinoroji ikoreshwa muburyo bwiza. Byakoreshejwe mugupima imikorere yimikorere ya optique. Nigihe-nyacyo cyo kugenzura uburyo bwa optique modules. Iyemerera abakoresha kugenzura ibipimo bya optique mugihe nyacyo, harimo imbaraga za optique, amashanyarazi yoherejwe, ubushyuhe bwo gukora, amashanyarazi ya voltage na laser bias. Noneho, gereranya agaciro gakurikiranwa nurwego rwagaciro rusabwa na optique module muburyo busanzwe bwakazi. Niba itari murwego rusabwa, impuruza izatangwa. Niba optique module yerekanwe kuba mumeze nabi ,.hinduraizahagarika kohereza amakuru, kandi ntabwo izohereza cyangwa kwakira amakuru kugeza igihe optique module iri mumiterere isanzwe.
Module optique DDM ikora ishingiye kubintu bisanzwe byagenwe na protocole ya SFF-8472. Porotokole ya SFF-8472 yerekana ibipimo ngenderwaho bisanzwe cyangwa urwego rugomba gukurikizwa na software hamwe nibikoresho bya optique ya modul optique hamwe nibikoresho byurusobe (nka switch), byemeza imikoranire yibicuruzwa bitangwa nabatanga ibikoresho bitandukanye byurusobe hamwe nabatanga module ya optique. Muri make, urutonde rwibipimo rusange bya OAM birashobora gusangirwa ninganda zose zitumanaho. Birakwiye ko tumenya ko ibicuruzwa bimwe byarenze ibisabwa mumasezerano. Imbonerahamwe ikurikira irerekana ibipimo ngenderwaho bya protocole ya SFF-8472 ya optique.
