Intshayelelo yePON Modyuli

Imodyuli yePON luhlobo lwemodyuli yokubona. IyasebenzaOLTizixhobo zetheminali kwaye iqhagamshela ngeI-ONUizixhobo zeofisi. Yinxalenye ebalulekileyo yenethiwekhi yePON. Iimodyuli ze-PON ezibonakalayo zingahlulwa zibe yi-APON (ATM PON) iimodyuli ze-optical, i-BPON (i-broadband passive network) iimodyuli ze-optical, i-EPON (Ethernet) iimodyuli ze-optical, kunye ne-GPON (i-gigabit passive network) iimodyuli ze-optical ngokwe-protocol yokudlulisa. Okwangoku, iimodyuli ze-EPON kunye neemodyuli ze-GPON ezibonakalayo zisetyenziswa kakhulu. Lo mzobo ulandelayo ubonisa imodyuli yokubona yeGPON.   Inxalenye yokudluliselwa kwe-PON imodyuli ye-optical ikwimo eqhubekayo. IOLTithumela umqondiso wombane ngesantya bit ethile ngomnwe wegolide kwimodyuli, kwaye uqhuba isixhobo BOSA ukuhambisa umqondiso optical modulated ngesantya ehambelanayo emva kokuba kusetyenzwe yitshiphu yomqhubi ngaphakathi kwimodyuli. Imodyuli inomsebenzi we-alamu yokubeka iliso yedijithali, engakwazi ukulawula ngokuzenzekelayo isiphaluka kwaye igcine ukuzinza kwe-output optical signal. Imodyuli ye-PON ikhupha ukukhanya kwi-1490nm.
Inxalenye yokufumana imodyuli yePON ikwimo yokugqabhuka. Xa imodyuli ifumana isignali ye-optical kunye neqondo elithile lekhowudi, i-optical diode yokufumanisa imodyuli iguqula ukukhanya okufunyenweyo kwisignali yombane, eyandisiweyo yi-preamplifier kwaye ikhupha umqondiso wombane kunye neqondo lekhowudi ehambelanayo.OLTIndawo yokukhwelela. Ubude bokukhanya obufunyenwe yimodyuli yePON yi-1310nm. Imodyuli yePON ngokubanzi inomgama wothumelo we-10KM kuphela okanye i-20KM. Uhlobo lojongano ngokuqhelekileyo lujongano lwe-SC, kwaye izinga lokusebenza ngokubanzi yi-gigabit okanye i-10 gigabit. Imodyuli yePON yokubona, njengenye yezixhobo eziyimfuneko zeFTTH, isetyenziswa ngokubanzi kuthungelwano lofikelelo. Oku kungentla yi-PON Module Intshayelelo evelaShenzhen HDV Phoelectron Technology Co., Ltd.
