    Nigute Combo PON ihuza na GPON na XGPON?

    Igihe cyo kohereza: Werurwe-17-2020

    Hamwe n’ishyirwa mu bikorwa ry’ingamba za “Broadband China” na “Kwihutisha no kugabanya amafaranga”, Ubushinwa bw’imiyoboro ihamye y’umuyoboro mugari bwagiye butera imbere; umukoresha mugari wahindutse kuva 10M no munsi ya 50M / 100M / 200M, kandi wahindutse ugana Gigabit; umuyoboro mugari wibikorwa remezo Mugutezimbere hamwe na videwo isobanura cyane na serivisi za interineti.

    Kugirango ugere ku gusimbuka kuva "100M" ujya kuri "Giga", tekinoroji ya PON igomba kuzamurwa ikagera kuri 10G PON. Imwe mu mbogamizi nyamukuru ku gipimo cyo kohereza 10G PON ni ikiguzi. Igiciro cyibikoresho 10G PON bikubiyemo ikiguzi cya optique, chipsets, hamwe nububiko bwa PCD. Igiciro cya optique modules na chipsets nikintu nyamukuru.

    Ubushinwa Telecom yo muri 2018 10G PON ikizamini cyo kugura no gupiganira isoko bikubiyemo ibice bitatu: GPON, 10G-EPON, nibikoresho bya XG-PON. Ubushinwa Mobile 2018 bwo gukusanya ibikoresho bya GPON burimo ibikoresho bya GPON, XG-PON, XGS-PON. XGS-PON ni ubwambere.

    GPON yazamuwe kuri XGPON1 cyangwa XGSPON. Kugeza ubu, igisubizo nyamukuru ku isoko nigisubizo cyo hanze cya multiplexer. Muri iki gisubizo, ibimenyetso bya GPON na XGPON1 / XGSPON bigwizwa muburyo bwa WDM wongeyeho ikarita yubuyobozi ya XGPON1 / XGSPON, hanyuma multiplexer yo hanze ikoherezwa kubakoresha kure. Ihame ryiki gisubizo kiroroshye cyane, ariko haribibi byinshi nkigihe cyo kuzamura igihe kirekire cyo gufungura, igiciro kinini, ibikoresho byinshi bifasha, hamwe nakazi gakomeye. Byongeye kandi, kumenyekanisha ibintu byinshi byo hanze bizana imbaraga zo gutakaza ingufu za optique, bizagira ingaruka. Ingaruka kubucuruzi busanzwe bwabakiriya.

    Combo PON ni ihuriro rya GPON na XGPON1 / XGSPON. Ihame ryayo ni ukumenya icyarimwe kwanduza no kwakirwa kwa GPON na XGPON1 / XGSPON ibimenyetso bya optique muburyo bwa optique, hamwe no guhuza uburebure bune butandukanye bwikwirakwiza binyuze mubikoresho byubatswe na WDM. Itanga interineti imwe ya fibre optique, ishobora guhuzwa na serivisi zisanzwe za GPON hamwe na serivisi za XGPON1 cyangwa XGSPON icyarimwe, twirinda impinduka kumiterere y'urusobe rusanzweho no kongeramo umwanya wibyumba, bityo ukagera kuri GPON idafite gahunda kandi ikora neza.

    Igishushanyo cya sisitemu ya Combo-PON

    Quad-OSA, ibikoresho bine bya optique ya Combo PONOLT.

    PON PONOLTprotocole ikubiyemo ibice bibiri bya protocole, GPON na XGPON, hamwe nibisobanuro byinshi. Hano hari N1, N2a, D1, D2 nibindi bisobanuro byingengo yimari ihuza. Mumagambo yoroshye, kugirango uhuze ningengo yimari ya 28dB na 32dB ya gakondo ya GPON B + na C +, XG (S) -PON ihuye ningengo yimishinga imwe niyo ifasha cyane kuzamura GPON kuri NGPON. Nibisobanuro bya D1 na D2 bihuye na Combo PON.

    Mu myaka mike ishize, gahunda yo kohereza imiyoboro ihuza imiyoboro ya Combo PON yagiye gahoro gahoro. Imwe mumpamvu nyamukuru nubukure bwurwego rwo gutanga ibikoresho bya fibre imwe ya fibre fibre optique kuri Combo PONOLTruhande, cyane cyane gukura kwingengo yimishinga ihuza ibikoresho byiza. impamyabumenyi. Kuva kera, igipimo cy'umusaruro w'amasosiyete akoresha ibikoresho bya optique muri Quad-OSA yo mu rwego rwo hejuru yahuye n’ibibazo bikomeye. Mu rwego rwo guteza imbere ikoreshwa rya Combo PON, impande zose zo mu nganda zateshutse kandi zemera gahunda y’inzibacyuho yo kugabanya N2a kugeza 31dB. Nyamara, kubisosiyete myinshi yibikoresho bya optique biteza imbere ibicuruzwa bya PON, umusaruro wibicuruzwa bya N2a byujuje ibisabwa Quad-OSA biracyafite igitutu, kandi umusaruro wibikoresho 32 bya optique 32 dB D2 biri hasi.

    Kurundi ruhande, kurwego rwo gusaba, abashoramari bategereje gukura byihuse byimikoreshereze yingengo yimari ihuza ibikoresho / optique modules. Mu Ihuriro ry’Ubushinwa Optical Network / FTTH 2018 ryabereye i Beijing muri Kamena uyu mwaka, abakora nka China Mobile na China Telecom baracyasaba neza ko ibikoresho bya optique D2 / optique bigizwe n’urwego rwo gutanga ibikoresho bikuze kugira ngo bishyigikire amakuru yose ya Combo PON.
