Sawubona Abafundi, Ngezansi sizokhuluma ngokuhlelwa kwamamojula e-PON futhi sizozama ukukuchaza kalula.
(1)OLToptical module futhiI-ONUimojuli ye-optical: Ngokwezigaba ezihlukene zamadivayisi we-plug-in kunezinhlobo ezimbili zamamojula we-PON optical:OLToptical module (le moduli ifakwe ikakhulukazi ku-OLTekugcineni, futhi ayikwazi ukwabelwa iI-ONUoptical module) kanyeI-ONU(le mojula ishuthekwa kakhulu kuyunithi yenethiwekhi yokubona) imojula yokubona. Iphakethe le-SFP.
Qaphela:OLTamamojula optical ayinkimbinkimbi kakhulu kuneI-ONUamamojula optical, ngoba ngayinyeOLTimojula ye-optical kufanele ikwazi ukudlulisa amasignali ngenani eliphakeme lama-64I-ONUamamojula optical.
(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. thayipha i-EPON ne-GPON.
Amamojula we-EPON optical ayatholakala kumaphakheji e-SFP, XFP kanye ne-SFP+, nebanga lokudlulisela elifika ku-20km, futhi ingxenye eyamukelayo ine-preamplifier evaliwe kanye ne-amplifier ekhawulelayo enokuphuma 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.
