1. CDR: Txoj haujlwm ntawm lub moos cov ntaub ntawv rov qab nti yog los txheeb lub moos lub teeb liab los ntawm lub teeb liab tawm tswv yim thiab nrhiav kev sib raug zoo theem ntawm lub teeb liab moos thiab cov ntaub ntawv, uas yog tsuas yog rov qab lub moos. Tib lub sijhawm, CDR kuj tseem tuaj yeem them nyiaj rau qhov poob ntawm cov xov tooj ntawm cov xaim thiab kab txuas.
2. LDD: Hloov cov teeb liab tso zis ntawm CDR rau hauv cov lus coj qhia coj los tsav lub laser ua lub teeb ci. Ntau yam ntawm cov lasers xav tau xaiv ntau hom LDD chips. Hauv luv-nrug ntau hom kho qhov muag module, feem ntau CDR thiab LDD yog sib xyaw ntawm tib lub nti.
3. TOSA: Txheeb hluav taws xob / kho qhov muag hloov pauv, feem ntau suav nrog laser, MPD, TEC, cais tawm, Mux, txuas lub teeb tsa thiab lwm yam khoom siv, nrog TO-CAN, Kub-BOX, COC, COB thiab lwm cov ntawv ntim khoom. Rau cov khoos phis tawm kho qhov muag siv nyob rau hauv cov chaw zov me nyuam cov ntaub ntawv, txhawm rau txuag cov nqi, TEC, MPD, thiab cov cais tawm tsis yog cov khoom tsim nyog. Mux kuj tseem siv nyob rau hauv cov kho qhov muag uas yuav tsum tau faib cov ntev sib faib. Ib qho ntxiv, LDD ntawm qee qhov khoos phis tawm kho qhov muag kuj tseem muaj nyob rau hauv TOSA.
