Sawubona Abafundi, Ngezansi sizokhuluma ngokuhlelwa kwamamojula e-PON futhi sizozama ukukuchaza kalula.
(1)Imodyuli ye-OLT ye-optical kanye ne-ONU optical module: Ngokwezigaba ezihlukene zamadivayisi e-plug-in kunezinhlobo ezimbili zamamojula we-PON optical: I-OLT optical module (le module ifakwe ikakhulukaziOLTekugcineni, futhi ayikwazi ukwabelwa iI-ONUimojula yokubona) kanye ne-ONU (le mojula ifakwe ikakhulukazi kuyunithi yenethiwekhi yokubona) imojula yokubona.Iphakethe le-SFP.
Qaphela: Amamojula okusebenza we-OLT ayinkimbinkimbi kakhulu kuneI-ONUamamojula optical, ngoba ngayinyeOLTimojuli ye-optical kumele ikwazi ukudlulisa amasiginali ngamamojula abonakalayo angama-64 ONU.
(2) Umehluko phakathi kwe-GPON optical module, i-EPON optical module kanye ne-APON optical module.Ngokwezigaba ezehlukene zamazinga obuchwepheshe (okungukuthi ama-transmission protocols),Amamojula e-PON optical angahlukaniswa abe izinhlobo ezine: I-APON iyi-ATM PON, i-BPON iyinethiwekhi ye-broadband passive optical, i-EPON iyinethiwekhi ye-Ethernet ye-passive optical kanye ne-GPON inethiwekhi ye-gigabit passive optical network.thayipha i-EPON ne-GPON.
Amamojula we-EPON optical ayatholakala kumaphakheji we-SFP, XFP kanye ne-SFP+, nebanga lokudlulisela elifika ku-20km, futhi ingxenye eyamukelayo ine-preamplifier evaliwe kanye ne-amplifier ekhawulayo enokukhishwa okuhlukile okuhambisanayo kwe-LVPECL.
I-GPON optical module iyimojula ye-optical esebenza kakhulu futhi eyongayo yezinhlelo zokusebenza zokuxhumana zedatha ye-serial optical ye-2.5Gpbs (i-downlink ingafinyelela izinga eliphezulu kakhulu).Inzuzo yale module ye-optical ukuthi ingaqinisekisa ukuthi akukho monakalo wamehlo kunoma yikuphi ukulimala kwesimo sephutha.
Okungenhla incazelo yezigaba zamamojula we-PON olethwe kuwe yi-Shenzhen HDV photoelectric Technology Company Ltd., Imikhiqizo yemojula ekhiqizwe ikhava yenkampaniamamojula we-fiber optical,Amamojula we-Ethernet,amamojula we-fiber optical transceiver,amamojula okufinyelela kwefiber optical,Amamojula we-SSFP optical, futhiImicu ye-Optical SFP.amamojula, njll. Imikhiqizo yemojula engenhla inganikeza ukwesekwa kwezimo zenethiwekhi ezahlukene.Kule mikhiqizo engenhla, ithimba le-R&D elichwepheshile nelinamandla linganikeza usekelo lobuchwepheshe kumakhasimende, futhi ithimba lebhizinisi elicabangayo nelichwepheshile lingahlinzeka ngamasevisi ekhwalithi ephezulu kumakhasimende ekubonisaneni kusenesikhathi kanye nomsebenzi wakamuva.Siyakwamukela kuXhumana nathinganoma yiluphi uhlobo lombuzo.
