DDM (Digital Diagnostic Monitoring) yog ib qho cuab yeej siv hauv optical modules.Nws yog siv los kuaj xyuas lub xeev ua haujlwm ntawm optical modules.Nws yog ib lub sij hawm ntawm parameter saib xyuas txhais tau tias ntawm optical modules.Nws tso cai rau cov neeg siv los saib xyuas qhov tsis zoo ntawm cov khoom siv kho qhov muag hauv lub sijhawm tiag tiag, suav nrog kev txais lub zog kho qhov muag, xa hluav taws xob kho qhov muag, kev ua haujlwm kub, hluav taws xob hluav taws xob thiab hluav taws xob laser tam sim no.Tom qab ntawd, sib piv tus nqi saib xyuas nrog tus nqi ntau yam uas xav tau los ntawm qhov kho qhov muag module nyob rau hauv ib txwm ua haujlwm.Yog tias nws tsis nyob hauv qhov xav tau, lub tswb yuav raug muab.Yog tias qhov kho qhov muag pom tau tias muaj qhov tsis zoo, qhov hloov pauv yuav tsum tsis txhob xa cov ntaub ntawv, thiab yuav tsis xa lossis tau txais cov ntaub ntawv ntxiv mus txog thaum lub optical module nyob rau hauv ib txwm muaj.
Optical module DDM ua haujlwm raws li tus qauv ntsuas qhov tseem ceeb uas tau teev tseg los ntawm SFF-8472 raws tu qauv.SFF-8472 raws tu qauv qhia cov qauv ntsuas qhov tseem ceeb lossis ntau yam uas yuav tsum tau ua raws li software thiab kho vajtse ntawm cov khoom siv kho qhov muag thiab cov khoom siv hauv network (xws li cov keyboards), ua kom muaj kev sib cuam tshuam ntawm cov khoom muab los ntawm cov khoom siv sib txawv network thiab cov khoom siv kho qhov muag.Hauv luv luv, cov txheej txheem ntawm OAM tsis tuaj yeem sib koom los ntawm tag nrho kev lag luam kev sib txuas lus.Nws yog tsim nyog sau cia tias qhov tseeb ntawm qee cov khoom lag luam tau dhau qhov kev xav tau ntawm qhov kev pom zoo.Cov lus hauv qab no qhia cov qauv ntsuas ntawm SFF-8472 raws tu qauv rau optical modules.
