Magaca buuxa ee moduleka indhaha waatransceiver indhaha, taas oo ah qalab muhiim u ah nidaamka isgaarsiinta fiber optic.Waxay mas'uul ka tahay inay u beddesho calaamadda indhaha ee la helay signal koronto, ama u beddelka calaamadda korantada ee gelinta signalka indhaha oo deggan oo u dhigma.
Themodule indhaha wuxuu ka kooban yahay aaladaha indhaha, wareegyada shaqada iyo is-dhexgalka indhaha.Aaladaha optoelectronic waxaa ka mid ah laba qaybood: gudbinta (TOSA) iyo helitaanka (ROSA).
Halbeegyada farsamo ee muhiimka ah ee moduleka indhaha waxaa ka mid ah celceliska awoodda indhaha ee la kala qaado, saamiga baabi'inta, dareenka helidda, iyo awoodda indhaha oo buuxda.
1. Celceliska awoodda indhaha ee la kala qaado waxa ay tilmaamaysaa celceliska xisaabta ee awoodda indhaha marka caqli-galku yahay 1 iyo awoodda indhaha marka ay tahay 0.
2. Saamiga dabar goynta waxaa loola jeedaa saamiga celceliska awoodda indhaha ee la kala qaado ee dhammaan "1" codes ilaa celceliska awoodda indhaha ee la gudbiyo ee dhammaan "0" kood.Waxay saamayn doontaa dareenka helitaanka.Saamiga dabar goynta waa in lagu xakameeyaa ilaa xad macquul ah.Saamiga baabi'inta weyn ayaa wax tar u leh in la dhimo ciqaabta Awoodda, laakiin aad u weyn waxay kordhin doontaa jitter-ka la xiriira laysarka.
3. Helitaanka dareenka waxa loola jeedaa xadka ugu yar ee dhamaadka helaya uu heli karo calaamada.Marka tamarta calaamada dhamaadka hesha ay ka yaraato heerka caadiga ah ee dareenka, dhamaadka helitaanka ma heli doono wax xog ah.
4. Qiimaha awoodda indhaha ee saturated waxa loola jeedaa awoodda indhaha ee ugu badan ee la ogaan karo dhamaadka helitaanka moduleka indhaha, guud ahaan -3dBm.Marka awoodda indhaha ee la helay ay ka weyn tahay awoodda indhaha ee saturated, khaladaad yar ayaa sidoo kale soo bixi doona.Sidaa darteed, haddii moduleka indhaha ee leh awoodda gudbinta sare ee indhaha la tijaabiyo iyada oo aan la yarayn iyo dib u dhac, khaladaad yar ayaa dhacaya.
