Molweni Abafundi, Ngezantsi ezantsi siza kuthetha malunga noHlelo lweeModyuli zePON kwaye siya kuzama ukukuchaza ngokulula.
(1)Imodyuli ye-OLT yokubona kunye nemodyuli ye-ONU yokubona: Ngokohlelo olwahlukileyo lwezixhobo zeplug-in kukho iindidi ezimbini zeemodyuli ezibonakalayo zePON: Imodyuli ye-OLT ebonakalayo (le modyuli ifakwe ikakhulu kwiOLTisiphelo, kwaye ayinakwabelwana ngayo neI-ONUimodyuli yokubona) kunye ne-ONU (le modyuli ifakwe ikakhulu kwiyunithi yenethiwekhi yokubona) imodyuli yokubona.Iphakheji ye-SFP.
Qaphela: Iimodyuli ze-OLT ezibonakalayo zinzima kakhulu kuneI-ONUiimodyuli zamehlo, kuba nganyeOLTimodyuli ye-optical kufuneka ikwazi ukuhambisa iimpawu kunye nobuninzi beemodyuli ze-ONU ze-64.
(2) Umahluko phakathi kwe-GPON imodyuli ye-optical, imodyuli ye-EPON kunye ne-APON imodyuli ye-optical.Ngokohlelo olwahlukeneyo lwemigangatho yobugcisa (oko kukuthi, iiprothokholi zothumelo),Iimodyuli ze-PON ezibonakalayo zinokwahlulwa zibe ziindidi ezine: i-APON yi-ATM ye-PON, i-BPON yinethiwekhi ye-broadband passive optical, i-EPON yinethiwekhi ye-Ethernet ye-passive optical kunye ne-GPON yi-gigabit passive network network.chwetheza iEPON kunye neGPON.
Iimodyuli ze-EPON ze-optical ziyafumaneka kwiiphakheji ze-SFP, i-XFP kunye ne-SFP +, kunye nomgama wokuhambisa ukuya kwi-20km, kwaye inxalenye yomamkeli ine-preamplifier etywiniweyo kunye ne-amplifier yokunciphisa kunye ne-LVPECL ehambelanayo ehambelanayo.
Imodyuli ye-GPON ye-optical module yimodyuli ephezulu yokusebenza kunye neyoqoqosho ye-serial optical data communication applications ye-2.5Gpbs (i-downlink inokufikelela kwizinga eliphezulu).Inzuzo yale modyuli ye-optical kukuba inokuqinisekisa ukuba akukho monakalo wamehlo kuyo nayiphi na imeko yempazamo.
Oku ngasentla yinkcazo yokuhlelwa kweemodyuli zePON eziziswe kuwe nguShenzhen HDV photoelectric Technology Company Ltd., Iimveliso zemodyuli eziveliswe 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.Iimodyuli, njl njl. Iimveliso zemodyuli ezingentla zinokubonelela ngenkxaso yeemeko ezahlukeneyo zenethiwekhi.Kwezi mveliso zingentla, iqela elinobuchule nelinamandla le-R&D linokubonelela ngenkxaso yobugcisa kubathengi, kwaye iqela leshishini elicingayo nelinobuchwephesha linokubonelela ngeenkonzo ezikumgangatho ophezulu kubathengi ngokubonisana kwangaphambili kunye nomsebenzi kamva.Wamkelekile kuweQhagamshelana nathikulo naluphi na uhlobo lombuzo.
