Njengoba “i-Gigabit Optical Network” ibhalwa embikweni womsebenzi kahulumeni ngokokuqala ngqá, kanye nezimfuno ezikhulayo zabathengi zekhwalithi yokuxhumeka, uguquko lwesibili lwe-optical “revolution” emlandweni wobubanzi bezwe lami luyaqaliswa.
Eminyakeni eyishumi edlule, opharetha baseShayina baye bashintsha ngaphezu kweminyaka eyi-100 yezintambo zethusi ezingena ekhaya zaba yi-fiber optical (FTTH), futhi ngalesi sisekelo, baye baqaphela ngokugcwele izinsizakalo zolwazi olusheshayo emindenini, futhi baqeda ukuguqulwa kokuqala kokubona."Inguquko" yabeka isisekelo samandla enethiwekhi.Eminyakeni eyishumi ezayo, i-all-optical fiber (FTTR) yenethiwekhi yasekhaya izoba yindlela entsha kanye nokudonsa.Ngokuletha i-gigabit kuwo wonke amagumbi, izodala izinsizakalo zolwazi ze-ultra-high-speed ezigxile kubantu namatheminali, futhi inikeze ulwazi lwezinga eliphezulu lwe-Broadband luzoqhubekisela phambili ukusheshisa ukwakhiwa kwamandla enethiwekhi kanye nomnotho wedijithali.
Umkhuba ojwayelekile wokufinyelela kwe-gigabit yasekhaya
Njengesisekelo somhlaba okhula ngokuba yidijithali, indima yokushayela i-broadband emnothweni wezenhlalo iyaqhubeka nokukhula.Ucwaningo olwenziwa yiBhange Lomhlaba lukhombisa ukuthi njalo ngo-10% ukwenyuka kokungena kwe-broadband kuzothuthukisa ukukhula kwe-GDP okuyisilinganiso esingu-1.38%;“Iphepha Elimhlophe Lokuthuthukiswa Komnotho Wedijithali Nokuqashwa KwaseShayina (2019)” libonisa ukuthi inethiwekhi yekhebula lentambo ye-fiber optical fiber yaseChina eyizigidi eziyi-180 yeseka ama-yuan ayizigidi eziyizinkulungwane ezingama-31.3 emnothweni wedijithali.ukuthuthukiswa kwe.Ngokufika kwe-F5G all-optical era, i-broadband nayo ibhekene namathuba amasha okuthuthukisa.
Kulo nyaka, kuhlongozwa ukuthi "kwandise ukwakhiwa kwamanethiwekhi e-5G namanethiwekhi optical gigabit, futhi kucebise izimo zohlelo lokusebenza";ngesikhathi esifanayo, "uhlelo lwe-14 lweminyaka emihlanu" luphinde lukhulume "ukukhuthaza nokuthuthukisa amanethiwekhi we-gigabit optical fiber."Ukukhuthaza amanethiwekhi okufinyelela e-broadband kusuka ku-100M kuya ku-Gigabit sekuphenduke isu elibalulekile ezingeni likazwelonke.
Emindenini, ukufinyelela kwe-gigabit nakho kuwumkhuba ojwayelekile.Ubhubhane olusha lwenyumoniya olusanda kuzalwa lukhuthaze ukukhula okunamandla kwamabhizinisi amasha namamodeli amasha.Umndeni awuseyona nje isizinda sempilo.Ngesikhathi esifanayo, futhi inezimfanelo zomphakathi njengezikole, izibhedlela, amahhovisi, nezinkundla zemidlalo yaseshashalazini, futhi isibe isikhungo sokukhiqiza sangempela., Futhi i-broadband yasekhaya iyisixhumanisi esiyinhloko esithuthukisa ukunwetshwa kwezimfanelo zomphakathi zomndeni.
Kepha ngasikhathi sinye, izinhlelo zokusebenza eziningi ezintsha zokuxhuma zilethe izinselelo eziningi ku-broadband yasekhaya.Isibonelo, uma ngibuka ukusakazwa bukhoma, amakilasi aku-inthanethi, nemihlangano eku-inthanethi, ngivame ukuhlangana nokungingiza, amafreyimu awehlisiwe, nomsindo nevidiyo engavumelanisiwe.Imizi eyi-100M kancane kancane ayanele.Ukuze kuthuthukiswe ulwazi oluku-inthanethi lwabathengi kanye nomuzwa wokuthenga, kuyaphuthuma ukuguqukela kumkhawulokudonsa we-gigabit, futhi uqhubeke nokwenza impumelelo kubukhulu bokubambezeleka, izinga lokulahleka kwephakethe, kanye nenombolo yoxhumo.
Eqinisweni, abathengi ngokwabo nabo "bavota ngezinyawo zabo" -ngokwethulwa kwezinsizakalo ze-gigabit broadband ngabasebenzisi ezifundazweni ezihlukahlukene, ababhalisi be-gigabit bezwe lami bangene esikhathini sokukhula okusheshayo ngonyaka odlule.Izibalo zibonisa ukuthi ekupheleni kuka-2020, inani labasebenzisi be-gigabit ezweni lami lisondele ezigidini ezingu-6.4, nezinga lokukhula lonyaka lika-700%.
I-FTTR: Ihola "inguquko" yesibili yokuguqulwa kokukhanya
Isiphakamiso sokuthi "Igumbi ngalinye lingafinyelela isipiliyoni sesevisi ye-Gigabit" sibonakala silula, kodwa sinzima.I-transmission medium okwamanje iyibhodlela elikhulu elikhawulela ubuchwepheshe benethiwekhi yasekhaya.Njengamanje, imikhawulo yesilinganiso yama-Wi-Fi adluliselwe, amamodemu wamandla we-PLC, namakhebuli enethiwekhi ngokuvamile acishe abe ngu-100M.Ngisho nemigqa ye-super-category 5 ayikwazi ukufinyelela ku-gigabit.Ngokuzayo, zizoguqukela kumugqa wesi-6 no-7.
Ngakho-ke, eminyakeni yamuva, imboni kancane kancane ibeka umugqa wokubona ku-fiber optical.Isixazululo senethiwekhi ye-FTTR gigabit all-optical room networking esekelwe ekwakhiweni kobuchwepheshe be-PON yisisombululo esiphezulu senethiwekhi yasekhaya, ngethemba lokunikeza imfundo ye-inthanethi, ihhovisi le-inthanethi, nokusakaza bukhoma.Amasevisi amasha afana nempahla, ukuzijabulisa kwe-e-sports, kanye nobuhlakani bendlu yonke ukuze kuzuzwe umuzwa wekhwalithi ephezulu we-broadband.Uchwepheshe omkhulu wemboni ukhombe i-C114, “Ukhiye wokunquma amandla omkhawulokudonsa yizimpawu zemvamisa yendawo yokudlulisela.Izici zokuvama kwama-optical fibers izikhathi ezingamashumi ezinkulungwane zezintambo zenethiwekhi.Impilo yobuchwepheshe yezintambo zenethiwekhi inqunyelwe, kuyilapho impilo yobuchwepheshe yamafiber optical ayinamkhawulo.Kumele sibheke inkinga ngeso lentuthuko.”
Ngokucacile, isixazululo se-FTTR sinezici ezine ezinkulu: isivinini esisheshayo, izindleko eziphansi, ukuguqulwa okulula, nokuvikelwa kwemvelo okuluhlaza.Okokuqala nje, i-optical fiber ibonwa njengendawo yokudlulisela eshesha kakhulu.Ubuchwepheshe bamanje bezentengiselwano bungafinyelela umthamo wokudlulisela wamakhulu e-Gbps.Ngemuva kokuthi i-fiber isetshenziswe endlini yonke, asikho isidingo sokushintsha imigqa yokuthuthukiswa kwesikhathi esizayo kunethiwekhi ye-10Gbps 10G, okungashiwo ukuthi kube kanye.Okwesibili, imboni ye-fiber optical ivuthiwe futhi imakethe izinzile.Intengo evamile ingaphansi kuka-50% wekhebula lenethiwekhi, futhi izindleko zokuguqulwa nazo ziphansi.
Okwesithathu, umthamo we-fiber optical cishe u-15% kuphela wekhebula lenethiwekhi evamile, futhi lincane ngosayizi futhi kulula ukulakha kabusha ngepayipi.Isekela i-fiber optical esobala, futhi umugqa ovulekile awulimazi umhlobiso, futhi ukwamukelwa komsebenzisi kuphezulu;kunezindlela eziningi zokuhlela, ezingavinjelwe izinhlobo zezindlu ezintsha nezindala, kanye nesikhala sohlelo lokusebenza Sikhudlwana.Okokugcina, impahla eluhlaza ye-fiber optical isihlabathi (i-silica), enobungani bemvelo futhi esimeme kunekhebula lenethiwekhi yethusi;ngesikhathi esifanayo, inomthamo omkhulu, ukumelana nokugqwala, nempilo yesevisi yeminyaka engaphezu kwengu-30.
Kubasebenzisi, i-FTTR izoba yindlela ephumelelayo yokufeza imisebenzi ehlukene necwengisisiwe yezinsizakalo ze-broadband yasekhaya, ukwakha umkhiqizo wenethiwekhi yasekhaya, nokwandisa i-ARPU yomsebenzisi;izophinde ihlinzeke ngezindlela ezidingekayo zokuthuthukiswa kwamakhaya ahlakaniphile kanye nomnotho omusha oxhumene.ukusekela.Ngokungeziwe kuhlelo lokusebenza ezimeni zokuxhumana zasekhaya, i-FTTR iphinde ifaneleke kakhulu ezakhiweni zamabhizinisi, amapaki nezinye izimo zenethiwekhi yendawo yezinkampani, ezingasiza opharetha ukuba basuke kumanethiwekhi wendawo ebanzi baye kumanethiwekhi wendawo ukuze bathole ukunamathela nabasebenzisi bezinkampani.
I-FTTR isilapha
Ngokuthuthuka okusheshayo kwenethiwekhi ye-optical yaseChina kanye nokuvuthwa kochungechunge lwezimboni, i-FTTR ayikude, iyabonakala.
NgoMeyi 2020, i-Guangdong Telecom kanye ne-Huawei ngokuhlanganyela bethula isixazululo senethiwekhi yasekhaya ye-FTTR yokuqala emhlabeni wonke, esibe wuphawu olubalulekile “lwenguquko” yesibili yenguquko yokubona kanye nesiqalo esisha sokuthuthukiswa kwezinsizakalo ze-broadband zasekhaya.Ngokubeka ama-optical fibers kuwo wonke amagumbi nokufaka iyunithi yenethiwekhi ye-Wi-Fi 6 optical kanye nebhokisi eliphezulu, lingakwazi ukusekela ukunethiwekha omkhulu okungu-1 kuye kwayi-16, ukuze wonke umuntu emndenini, kuwo wonke amagumbi, futhi ngaso sonke isikhathi abe nolwazi oluyigigabit ye-Broadband. .
Njengamanje, isixazululo se-FTTR esisekelwe kubuchwepheshe be-PON sikhishwe ngokudayisa ezifundazweni nasemadolobheni angu-13 okuhlanganisa i-Guangdong, iSichuan, i-Tianjin, i-Jilin, i-Shaanxi, i-Yunnan, i-Henan, njll., kanye nabaqhubi ezifundazweni nasemadolobheni angaphezu kuka-30 sebeqedile. uhlelo lokuhlola kanye nesinyathelo esilandelayo sokuhlela .
Ngokuqhutshwa “uHlelo Lweminyaka Eyi-14 Lweminyaka Emihlanu”, “ingqalasizinda entsha” nezinye izinqubomgomo ezivumayo, kanye nesidingo semakethe sokuhlangenwe nakho kwabathengi ekhaya “kusuka kokuhle kuya kokuhle” kanye “nokusuka kokuhle kuya kokungcono”, kulindeleke ukuthi I-FTTR izoba eminyakeni emihlanu ezayo.Izongena emakhaya angama-40% eShayina, iqhubeke nokugqugquzela ukuthuthukiswa kwekhwalithi ephezulu "ye-Broadband China", ivule indawo yemakethe yezinkulungwane zezigidigidi, futhi iqhubekise ukukhula kwezigidigidi zezinhlelo zokusebenza zedijithali kanye nemboni yasekhaya ehlakaniphile.
I-Shenzhen HUANET Technology CO., Ltd. Futhi ihlinzeka nge-GPON OLT, ONU kanye ne-PLC Splitter kuma-opharetha amaphrojekthi amaningi.
