Ngokubhalwa kwe "Gigabit Optical Network" kwingxelo yomsebenzi karhulumente okokuqala, kunye neemfuno ezikhulayo zabathengi zomgangatho woxhumo, uhlaziyo lwesibini lwe-optical "revolution" kwimbali ye-broadband yelizwe lam luyacinywa.
Kwiminyaka elishumi edlulileyo, abaqhubi baseTshayina batshintshile kwiminyaka eyi-100 yokungena ekhaya iingcingo zobhedu kwi-fiber optical (FTTH), kwaye ngenxa yesi siseko, baye baqonda ngokupheleleyo iinkonzo zolwazi olukhawulezayo kwiintsapho, kwaye bagqiba ukuguqulwa kokuqala kwe-optical."Revolution" yabeka isiseko sombane womnatha.Kwiminyaka elishumi ezayo, i-fiber yonke ye-optical (FTTR) yenethiwekhi yasekhaya iya kuba yindlela entsha kunye ne-traction.Ngokuzisa i-gigabit kuwo onke amagumbi, kuya kudala iinkonzo zolwazi ze-ultra-high-speed ezijoliswe kubantu kunye nee-terminals, kwaye zibonelele ngamava e-Broadband akumgangatho ophezulu uya kukhawulezisa ukwakhiwa kwamandla womnatha kunye noqoqosho lwedijithali.
Indlela eqhelekileyo yokufikelela kwigigabit yasekhaya
Njengoko ilitye lembombo lehlabathi eliya lifakwa ekhompyutheni, indima yokuqhubela phambili kwebroadband kuqoqosho lwentlalo iyaqhubeka nokukhula.Uphando olwenziwe yiBhanki yeHlabathi lubonisa ukuba rhoqo nge-10% yokwanda kokungena kwi-broadband kuya kuqhuba umndilili wokukhula kwe-GDP oyi-1.38%;“iPhepha leNgcaciso yoMgaqo-nkqubo kuPhuhliso lweDijithali kuQoqosho kunye neNgqesho yaseTshayina (ngowama-2019)” libonisa ukuba uthungelwano lwentambo yentambo yocweyo lwe-fiber optical fiber yaseTshayina ezizigidi ezili-180 ixhasa i-31.3 yetriliyoni yeeyuan kuqoqosho lwedijithali.Uphuhliso lwe.Ngokufika kwexesha le-F5G all-optical era, i-broadband ijongene namathuba amatsha ophuhliso.
Kulo nyaka, kucetywayo "ukwandisa ukwakhiwa kweenethiwekhi ze-5G kunye ne-gigabit optical networks, kunye nokuphucula iimeko zesicelo";kwangaxeshanye, "iSicwangciso seMinyaka emiHlanu ye-14" sikwakhankanya "ukukhuthaza nokuphucula i-gigabit optical fiber networks."Ukukhuthaza amanethiwekhi okufikelela kwi-broadband ukusuka kwi-100M ukuya kwi-Gigabit kuye kwaba sisicwangciso esibalulekileyo kwinqanaba likazwelonke.
Kwiintsapho, ukufikelela kwegigabit kukwayindlela eqhelekileyo.Ubhubhani omtsha wenyumoniya ngequbuliso ukhuthaze ukukhula kwamashishini amatsha kunye neemodeli ezintsha.Intsapho ayisekho nje isazulu sobomi.Kwangaxeshanye, ikwaneempawu zentlalo ezifana nezikolo, izibhedlele, iiofisi, nethiyetha, yaye iye yaba liziko lokwenene lemveliso., Kwaye i-broadband yekhaya likhonkco eliphambili elikhuthaza ukwandiswa kweempawu zentlalo yentsapho.
Kodwa kwangaxeshanye, izicelo ezininzi zoqhagamshelo ezitsha zizise imiceli mngeni emininzi kwibroadband yasekhaya.Umzekelo, xa ndibukele usasazo oluphilayo, iiklasi ze-intanethi, kunye neentlanganiso ezikwi-intanethi, ndihlala ndidibana nokungathintitha, ukuwisa iifreyimu, kunye neaudio kunye nevidiyo engahambelaniyo.Imizi eyi-100M ayonelanga kancinci kancinci.Ukuze uphucule amava abathengi kwi-intanethi kunye nokuqonda kokufunyanwa, kungxamisekile ukuvela kwi-gigabit bandwidth, kwaye nokuqhubeka nokwenza impumelelo kwimilinganiselo ye-latency, ireyithi yokulahleka kwepakethi, kunye nenani loqhagamshelo.
Enyanisweni, abathengi ngokwabo "bavota ngeenyawo zabo" -ngokuqaliswa kweenkonzo ze-gigabit broadband ngabaqhubi kumaphondo ahlukeneyo, ababhalisi be-gigabit belizwe lam bangene kwixesha lokukhula ngokukhawuleza kulo nyaka uphelileyo.Izibalo zibonisa ukuba ekupheleni kwe-2020, inani labasebenzisi be-gigabit kwilizwe lam lisondele kwi-6.4 yezigidi, kunye nezinga lokukhula lonyaka le-700%.
I-FTTR: Ikhokela "i-revolution" yesibini yokuguqulwa kokukhanya
Isiphakamiso esithi "Igumbi ngalinye linokufikelela kwinkonzo yamava eGigabit" kubonakala kulula, kodwa kunzima.Indawo yosasazo okwangoku yeyona nto ithintela itekhnoloji yothungelwano lwasekhaya.Okwangoku, imida yereyiti ye-Wi-Fi eqhelekileyo, iimodem zamandla ze-PLC, kunye neentambo zenethiwekhi ubukhulu becala zijikeleze i-100M.Nkqu ne-super-category 5 imigca ayinako ukufikelela kwi-gigabit.Kwixesha elizayo, ziya kuguqukela kwiCandelo lesi-6 kunye nemigca yesi-7.
Ke ngoko, kwiminyaka yakutshanje, ishishini liye labeka ngokuthe ngcembe umgca wokubona kwifiber optical.Isisombululo se-FTTR gigabit all-optical room networking networking based on the PON technology architecture sesona sisombululo sonxibelelwano lwekhaya, sinethemba lokusebenzela imfundo ye-intanethi, iofisi ye-intanethi, kunye nokusasazwa ngokuphila.Iinkonzo ezintsha ezinje ngempahla, ukuzonwabisa kwemidlalo ye-elektroniki, kunye nobukrelekrele bendlu yonke ukuphumeza amava ebroadband ekumgangatho ophezulu.Ingcaphephe yoshishino ephezulu yalatha kwi-C114, “Isitshixo ekumiseleni umthamo we-bandwidth ziimpawu zokuphindaphinda kwendlela yothumelo.Iimpawu ze-frequency of optical fibers ngamashumi amawaka amaxesha eentambo zenethiwekhi.Ubomi bobugcisa beentambo zenethiwekhi bukhawulelwe, ngelixa ubomi bobugcisa bee-fibers optical abukhawulelwanga.Kufuneka siyijonge le ngxaki ngokwembono yophuhliso.”
Ngokukodwa, isisombululo seFTTR sineempawu ezine eziphambili: isantya esikhawulezayo, ixabiso eliphantsi, ukuguqulwa okulula, kunye nokukhuselwa kokusingqongileyo okuluhlaza.Okokuqala, i-optical fiber yamkelwa njengeyona ndlela yokuhambisa ngokukhawuleza.Itekhnoloji yangoku yorhwebo inokufikelela kwisakhono sothumelo samakhulu eGbps.Emva kokuba i-fiber isetyenziswe kwindlu yonke, akukho mfuneko yokutshintsha imigca yokuphuculwa kwexesha elizayo kwinethiwekhi ye-10Gbps ye-10G, enokuthi ibe kanye kunye.Okwesibini, ishishini lefiber optical livuthiwe kwaye imarike izinzile.Ixabiso eliphakathi lingaphantsi kwe-50% yentambo yenethiwekhi, kwaye iindleko zenguqu nazo ziphantsi.
Okwesithathu, umthamo wefiber optical kuphela malunga ne-15% yentambo yenethiwekhi eqhelekileyo, kwaye incinci ngobukhulu kwaye kulula ukuyivuselela ngombhobho.Ixhasa i-fiber optical ebonakalayo, kwaye umgca ovulekileyo ungonakalisi umhlobiso, kwaye ukwamkelwa komsebenzisi kuphezulu;kukho iindlela ezininzi zoyilo, ezingathintelwanga ziindidi zendlu entsha nendala, kunye nesithuba sesicelo Esikhulu.Ekugqibeleni, i-raw material ye-fiber optical is sand (silica), ehambelana nokusingqongileyo kwaye izinzileyo kunekhebula lomnatha wobhedu;ngelo xesha, inomthamo omkhulu, ukuxhathisa ukubola, kunye nobomi benkonzo obungaphezu kweminyaka engama-30.
Kubaqhubi, i-FTTR iya kuba yindlela esebenzayo yokuphumeza imisebenzi eyahlukileyo kunye nesulungekileyo yeenkonzo ze-broadband zasekhaya, ukwakha uphawu lwenethiwekhi yasekhaya, kunye nokwandisa i-ARPU yomsebenzisi;iya kubonelela ngeendlela eziyimfuneko zophuhliso lwamakhaya ahlakaniphile kunye noqoqosho olutsha oludibeneyo.inkxaso.Ukongeza kwisicelo kwiimeko zothungelwano lwasekhaya, i-FTTR ikwafaneleka kakhulu kwizakhiwo zoshishino, iipaki kunye nezinye iimeko zothungelwano lwengingqi, ezinokunceda abaqhubi bandise ukusuka kuthungelwano lwendawo ebanzi ukuya kuthungelwano lwengingqi ukuseka ukuncamathela kunye nabasebenzisi beenkampani.
I-FTTR ilapha
Ngophuhliso olukhawulezayo lwenethiwekhi ye-optical yaseTshayina kunye nokuvuthwa kwekhonkco lezoshishino, i-FTTR ayikho kude, iyabonakala.
NgoMeyi ka-2020, i-Guangdong Telecom kunye neHuawei ngokudibeneyo basungule isisombululo sokuqala se-FTTR senethiwekhi yasekhaya ye-All-optical yehlabathi, eye yaba luphawu olubalulekileyo lwesibini "lwenguquko" yohlaziyo lwamehlo kunye nesiqalo esitsha sophuhliso lweenkonzo zebroadband zasekhaya.Ngokubeka iintsinga zamehlo kwigumbi ngalinye kunye nokubeka iyunithi yenethiwekhi ye-Wi-Fi 6 kunye nokuseta ibhokisi ephezulu, inokuxhasa i-1 ukuya kwe-16 yothungelwano oluphezulu, ukuze wonke umntu entsatsheni, kwigumbi ngalinye, kwaye ngalo lonke ixesha abe namava e-super gigabit Broadband. .
Okwangoku, isisombululo se-FTTR esisekelwe kubuchwephesha be-PON sikhutshwe ngokurhweba ngabaqhubi kumaphondo e-13 kunye nezixeko ezibandakanya i-Guangdong, iSichuan, i-Tianjin, i-Jilin, i-Shaanxi, i-Yunnan, i-Henan, njl. inkqubo yokulinga kunye nenyathelo elilandelayo lokucwangcisa .
Iqhutywa “siSicwangciso seMinyaka emiHlanu ye-14”, “iziseko ezingundoqo ezitsha” kunye neminye imigaqo-nkqubo encomekayo, kwakunye nemfuno yentengiso yamava omthengi asekhaya “ukusuka kokulungileyo ukuya kokulungileyo” kunye “ukusuka kokulungileyo ukuya kokungcono”, kulindeleke ukuba I-FTTR iya kuba kule minyaka mihlanu izayo.Iza kungena kwi-40% yamakhaya e-China, iqhubeke nokukhuthaza uphuhliso oluphezulu lwe-"Broadband China", ivule indawo yemarike yamakhulu eebhiliyoni, kwaye iqhube ukukhula kweebhiliyoni zezicelo zedijithali kunye noshishino lwasekhaya oluhlakaniphile.
I-Shenzhen HUANET Technology CO., Ltd. Kwakhona ukubonelela nge-GPON OLT, i-ONU kunye ne-PLC Splitter kubaqhubi beeprojekthi ezininzi.
