Molo, Wamkelekile.Masifunde uthelekiso phakathi kweemodyuli ze-GPON kunye ne-EPON kwinkcazo elula.
Imodyuli yokubona yeGPON inokusebenza okungcono kunemodyuli ye-EPON yokubona.Ngokwesantya, i-downlink ingcono kune-EPON;Ngokweshishini, i-GPON igubungela uluhlu olubanzi;Ukusuka kubuntununtunu bothumelo, kungcono kune-EPON.Nangona kunjalo, imodyuli ye-EPON ye-optical ineenzuzo ezininzi kwiindleko.Ezi zimbini zineenzuzo zazo kunye nezingeloncedo, ezinokuhlalisana kwaye ziyancedisana.
Makhe sijonge iteknoloji yeGPON.Ukususela kwimiba yokusetyenziswa kwe-bandwidth, iindleko, inkxaso yeenkonzo ezininzi, umsebenzi we-OAM kunye nokunye, i-GPON ingcono kune-EPON.I-GPON isebenzisa ikhowudi yokukrazula njengekhowudi yomgca, ukutshintsha kuphela ikhowudi ngaphandle kokunyusa ikhowudi, ngoko akukho kulahleka kwe-bandwidth ekuhanjisweni;Ngesantya esiphezulu se-Gigabit (i-downlink 2.5Gbps), ixabiso liphantsi ngokwexabiso elincinci;Ngenxa yefom yokupakisha ekhethekileyo, inokuxhasa kakuhle iinkonzo ze-ATM kunye neenkonzo ze-IP;I-OAM ityebile ngolwazi, kubandakanywa ukunikezelwa kogunyaziso lwe-bandwidth, i-dynamic bandwidth allocation (DBA), ukubeka iliso kwikhonkco, ukutshintshwa kokukhusela, ukutshintshiselana okubalulekileyo kunye nemisebenzi eyahlukeneyo ye-alamu.
Ukudibanisa, xa ukhetha i-GPON kunye ne-EPON: ukuba abasebenzisi baneemfuno eziphezulu ze-bandwidth, iinkonzo ezininzi, i-QoS kunye nokhuseleko, kunye nobuchwepheshe be-ATM njengenethiwekhi ye-backbone, kucetyiswa ukuba ukhethe imodyuli ye-GPON optical;Ukuba ufuna ukugcina iindleko kwaye uneemfuno eziphantsi ze-QoS kunye nokhuseleko, iimodyuli ze-EPON ezibonakalayo zinokuthi zifaneleke ngakumbi.Ungakhumbula: khetha iGPON yakho yokusebenza okuphezulu kunye nenkonzo ezininzi;Abaqhelekileyo bangakhetha iEPON enexabiso eliphantsi.
Oku kungasentla luthelekiso lwentsebenzo phakathi kwemodyuli yokubona yeGPON kunye nemodyuli yokukhanya ye-EPON eziswe kuwe yiShenzhen HDV photoelectric Technology Co., Ltd.Imveliso yemodyuli eveliswe yikhava yenkampani.iimodyuli zefiber optical, Iimodyuli ze-Ethernet, iimodyuli ze-fiber optical transceiver, iimodyuli zokufikelela kwifiber optical, Iimodyuli ze-SSFP ezibonakalayo, kwayeI-SFP optical fibers, njl. Ezi mveliso zemodyuli zingentla zinokubonelela ngenkxaso yeemeko ezahlukeneyo zenethiwekhi.Iqela le-R&D elinobuchwephesha kunye nelomeleleyo linokunceda abathengi abanemiba yobugcisa, kwaye iqela leshishini elicingayo nelinobuchule linokunceda abathengi bafumane iinkonzo ezikumgangatho ophezulu ngexesha lokubonisana kwangaphambili kunye nomsebenzi wasemva kokuvelisa.Wamkelekile kuweQhagamshelana nathikulo naluphi na uhlobo lombuzo.
