    10G PON Technology Development

    Nako ea poso: Sep-04-2023

    (1) 10G PON Tsela ea ntlafatso ea Theknoloji

    EPON e busoang ke IEEE, le GPON e busoang ke ITU ka bobeli li fetohela sethaleng sa 10 GPON hajoale mme moralo o latelang ke 100G PON ka bobeli. Ho na le liphapang tse itseng litseleng tse ikhethileng tsa ho iphetola ha lintho, 'me tsela e tsamaellanang le eona e bonts'oa setšoantšong se latelang:

    (2) EPON theknoloji ea ho iphetola ha lintho

    The 10G EPON symmetric and asymmetric technical standards and products have been perfected, Ho phaella moo, e na le molemo oa ho phela hammoho le EPON terminal ka marang-rang a tšoanang a ODN ntle le ho eketsa multiplexer. Ka mor'a ho reka thepa e bohareng eaOLTka 2016, li-module tsa OLT's 10G PON Optical li theohile ka theko.

    . Ha re nahana ka tsoelo-pele ea nakong e tlang ea marang-rang, basebetsi ba ile ba qala ho hlahisa 10G EPON esale pele qetellong ea sebaka seo, 'me ba ntse ba sebelisa EPON ONT ho mofani oa ho etsa FTTH kaho. Ka nako e ts'oanang, hobane phapang ea theko pakeng tsa symmetric optical module le asymmetric optical module ha e kholo, 'me ha ho nahanoa ka karolelano ea bandwidth ea 10G EPON ea holimo le tlaase ho ea holimo ke 1:10, e le ho qoba tlhokahalo ea ntlafatso e bakoang ke se latelang. nts'etsopele ea lits'ebeletso tsa uplink, basebelisi ba na le tšekamelo ea ho sebelisa 10G EPON symmetric mode hoOLTlehlakore. Mohato o latelang oa EPON o tla fetohela ho theknoloji ea 100G PON.

    (3) GPON theknoloji ea ho iphetola ha lintho

    Bakeng sa maemo a 10G GPON, maemo a tekheniki a asymmetric XG-PON le lihlahisoa li entsoe hantle. The wavelength e tsitsitseng symmetric 10G GPON standard XGS-PON e ile ea lokolloa ka February 2016. Ka lebaka la lisebelisoa tse batlang li hōlile tse amehang ka mokhoa o tloaelehileng, lihlahisoa tse ling tsa baetsi ba lihlahisoa li itokiselitse ho sebelisoa khoebong. Tekanyetso ea NGPON2 (TWDMPON) e nang le maqhubu a feto-fetohang a phethiloe. Hajoale,OLTlihlahisoa li 'nile tsa rekisoa Europe le Amerika.Ka nako e ts'oanang, ho na le lihlahisoa tsa MDU tse tsamaisanang le' maraka oa khoebo o inehetseng. Optical module e nang le wavelength e feto-fetohang ea NGPON2 e theko e boima ebile e thata ho e finyella.Ka mor'a hore ITU e tlatse mokhoa oa symmetrical fixed wavelength 10G standard (XGS-PON), baetsi ba bang ba lumela hore NGPON2 e ka 'na ea tlōla' me ea fetoha ka ho toba ho tharollo ea 4 * 25G 100G PON, 'me hoa khoneha ho kopanya le 100G EPON standard.

    Ka nako e khutšoanyane, theko ea ONT ea 10G PON e ke ke ea oela ho theko e teng ea EPON / GPON, kahoo ho ke ke ha qojoa ho tobana le boemo ba ho phela hammoho ha 10 GPON le lehlakoreng la mosebedisi EPON / GPON terminal. Hobane li-terminals tsa GPON le XGPON li kopane ka marang-rang a tšoanang a ODN, li-module tsa WDM1r li hloka ho eketsoa, ​​​​e leng ho fokotsang ho kenngoa ha XG-PON marang-rang a hona joale. Ka hona, bahlahisi ba molemo ba na le morero oa Combo PON oa encapsulate GPON le XGPON optical modules le WDM1r ka mochine o le mong oa optical. Leha ho le joalo, optical module ea Combo PON scheme e ka kenngoa feela ke XFP, 'me boto e le' ngoe e ka lemoha likou tse 8 tsa PON (tse tloaelehileng.SFP+ ho paka, 'me boto e le' ngoe e ka fumana likou tse 16 tsa PON). Ho sa le joalo, ka lebaka la keketseho ea tahlehelo ea ho kenya WDM1r, litlhoko tsa matla tse khanyang tsa optical modules li phahame. Hajoale, matla a khanyang a B +/N1 a ka phethahala feela, 'me mojule oa matla a phahameng oa C +/N2a o ke ke oa fanoa ka nako e khuts'oane, e fokotsang ts'ebeliso ea maemo a malelele a boholo ba spectral ratio.

    Ka holimo ke tlhaloso ea EPON le ho iphetola ha thekenoloji. Lihlahisoa tsa marang-rang tsa Shenzhen HDV photoelectron Technology Co., Ltd. kaofela ke lisebelisoa tse hlahisoang ho pota-pota marang-rang a PON, ho kenyeletsaONUletoto /OLTseries / optical module series / transceiver series joalo-joalo. E le ho theha thepa e ntle haholo ea marang-rang, k'hamphani ea rona e na le sehlopha sa lipatlisiso le nts'etsopele ea litsebi, ho fana ka litšebeletso tsa boleng bo phahameng ba tšehetso ea tekheniki ho bareki, ho amoheloa ho batla basebetsi ho utloisisa lihlahisoa tsa rona.
