Popeza "Gigabit Optical Network" yalembedwa mu lipoti la ntchito la boma koyamba, komanso zofuna za ogula kuti azitha kulumikizana bwino, kusintha kwachiwiri kwa "kusintha" kwa kuwala m'mbiri ya intaneti ya dziko langa kukuyambitsidwa.
M'zaka khumi zapitazi, ogwira ntchito ku China asintha mawaya amkuwa olowera m'nyumba kwa zaka zoposa 100 kukhala ulusi wowala (FTTH), ndipo pachifukwa ichi, akwaniritsa bwino ntchito zodziwitsa mabanja mwachangu, ndipo amaliza kusintha koyamba kwa kuwala. "Revolution" idakhazikitsa maziko a mphamvu ya netiweki. M'zaka khumi zikubwerazi, ulusi wowala (FTTR) wa netiweki yapakhomo udzakhala njira yatsopano komanso yogwirira ntchito. Mwa kubweretsa gigabit m'chipinda chilichonse, ipanga ntchito zodziwitsa mwachangu kwambiri zomwe zimayang'ana anthu ndi malo ofikira, ndikupereka chidziwitso chapamwamba cha Broadband chomwe chidzafulumizitsa kumanga mphamvu ya netiweki komanso chuma cha digito.
Chizolowezi chogwiritsa ntchito gigabit kunyumba
Monga mwala wa dziko lomwe likukula kwambiri pa digito, gawo lotsogolera la broadband mu chuma cha anthu likupitilira kukula. Kafukufuku wa World Bank akuwonetsa kuti kuwonjezeka kulikonse kwa 10% kwa kulowa kwa broadband kudzayendetsa kukula kwapakati pa GDP kwa 1.38%; "White Paper on China's Digital Economy Development and Employment (2019)" ikuwonetsa kuti netiweki ya chingwe cha optical fiber ya 180 miliyoni ku China imathandizira ma yuan 31.3 trillion mu chuma cha digito. Ndi kubwera kwa nthawi ya F5G yonse yowala, broadband ikukumananso ndi mwayi watsopano wopititsa patsogolo.
Chaka chino, akulangizidwa kuti "awonjezere ntchito yomanga maukonde a 5G ndi maukonde a gigabit, ndikuwonjezera njira zogwiritsira ntchito"; nthawi yomweyo, "Dongosolo la Zaka Zisanu la 14" limatchulanso "kulimbikitsa ndikusintha maukonde a gigabit optical fiber." Kulimbikitsa maukonde olumikizirana ndi intaneti kuchokera pa 100M kupita ku Gigabit kwakhala njira yofunika kwambiri pamlingo wadziko lonse.
Kwa mabanja, mwayi wopeza gigabit ndi chinthu chomwe chikuchitika kwambiri. Mliri watsopano wa chibayo cha korona wapangitsa kuti mabizinesi atsopano ndi mitundu yatsopano ikule kwambiri. Banja sililinso likulu la moyo. Nthawi yomweyo, lilinso ndi makhalidwe abwino monga masukulu, zipatala, maofesi, ndi malo ochitira zisudzo, ndipo lakhala malo enieni ochitira zinthu. Ndipo intaneti yapakhomo ndiye ulalo waukulu womwe umalimbikitsa kufalikira kwa makhalidwe abwino a banja.
Koma nthawi yomweyo, mapulogalamu ambiri atsopano olumikizirana abweretsa mavuto ambiri pa intaneti. Mwachitsanzo, ndikaonera mawayilesi amoyo, makalasi apaintaneti, ndi misonkhano yapaintaneti, nthawi zambiri ndimakumana ndi chibwibwi, mafelemu otayika, komanso mawu ndi makanema osalumikizidwa. Mabanja a 100M pang'onopang'ono sakwanira. Pofuna kukulitsa zomwe ogula akumana nazo pa intaneti komanso kumva kuti akufuna kugula, ndikofunikira kusintha kukhala gigabit bandwidth, komanso kupitilizabe kupanga zatsopano mu kukula kwa kuchedwa, kuchuluka kwa kutayika kwa paketi, ndi kuchuluka kwa maulumikizidwe.
Ndipotu, ogula nawonso “akuvota ndi mapazi awo” - ndi kuyambitsidwa kwa ntchito za gigabit broadband ndi ogwira ntchito m'maboma osiyanasiyana, olembetsa gigabit m'dziko langa alowa munthawi yakukula mwachangu chaka chatha. Ziwerengero zikuwonetsa kuti pofika kumapeto kwa chaka cha 2020, chiwerengero cha ogwiritsa ntchito gigabit m'dziko langa chili pafupi ndi 6.4 miliyoni, ndi kukula kwa pachaka kwa 700%.
FTTR: Kutsogolera "kusintha" kwachiwiri kwa kusintha kwa kuwala
Lingaliro lakuti “Chipinda chilichonse chingathe kukwaniritsa ntchito ya Gigabit” likuoneka losavuta, koma ndi lovuta. Pakadali pano njira yotumizira mauthenga ndiyo vuto lalikulu kwambiri pa ukadaulo woletsa kulumikizana kwapakhomo. Pakadali pano, malire a liwiro la ma Wi-Fi relay akuluakulu, ma modemu amphamvu a PLC, ndi zingwe za netiweki ali pafupifupi 100M. Ngakhale mizere 5 yapamwamba kwambiri singafikire gigabit. M'tsogolomu, idzasanduka mizere ya Gulu 6 ndi 7.
Chifukwa chake, m'zaka zaposachedwa, makampaniwa pang'onopang'ono ayamba kugwiritsa ntchito ulusi wowala. Njira yothetsera kulumikizana kwa chipinda cha FTTR gigabit all-optical kutengera kapangidwe ka ukadaulo wa PON ndiyo njira yabwino kwambiri yolumikizirana kunyumba, yomwe ikuyembekeza kupereka maphunziro apaintaneti, maofesi apaintaneti, ndi kuwulutsa pompopompo. Ntchito zatsopano monga katundu, zosangalatsa zamasewera apaintaneti, ndi luntha la nyumba yonse kuti zikwaniritse luso lapamwamba la broadband. Katswiri wamkulu wamakampani adauza C114 kuti, "Chinsinsi chodziwira mphamvu ya bandwidth ndi momwe ma frequency a media amagwiritsidwira ntchito. Ma frequency a ulusi wowala ndi nthawi masauzande ambiri kuposa ma network. Moyo waukadaulo wa ma network ndi wochepa, pomwe moyo waukadaulo wa ma fiber owala ndi wopanda malire. Tiyenera kuyang'ana vutoli kuchokera pamalingaliro a chitukuko."
Makamaka, yankho la FTTR lili ndi makhalidwe anayi akuluakulu: liwiro lachangu, mtengo wotsika, kusintha kosavuta, komanso kuteteza chilengedwe chobiriwira. Choyamba, ulusi wowala umadziwika kuti ndi njira yotumizira mwachangu kwambiri. Ukadaulo wamakono wamalonda ukhoza kukwaniritsa mphamvu yotumizira ya mazana a Gbps. Ulusi ukayikidwa mnyumba yonse, palibe chifukwa chosinthira mizere kuti musinthe mtsogolo kukhala netiweki ya 10Gbps 10G, yomwe inganenedwe kuti ndi kamodzi kokha. Kachiwiri, makampani opanga ulusi wowala ndi okhwima ndipo msika ndi wokhazikika. Mtengo wapakati ndi wotsika kuposa 50% ya chingwe cha netiweki, ndipo mtengo wosinthira nawonso ndi wotsika.
Chachitatu, kuchuluka kwa ulusi wa kuwala ndi pafupifupi 15% yokha ya chingwe cha netiweki wamba, ndipo ndi kakang'ono kukula kwake ndipo ndikosavuta kumanganso kudzera mu chitoliro. Chimathandizira ulusi wowonekera bwino, ndipo mzere wotseguka suwononga zokongoletsera, ndipo kuvomerezedwa kwa ogwiritsa ntchito ndikokwera; pali njira zambiri zokonzera, zomwe sizimaletsedwa ndi mitundu yatsopano ndi yakale ya nyumba, komanso malo ogwiritsira ntchito ndi akulu. Pomaliza, zinthu zopangira ulusi wa kuwala ndi mchenga (silika), womwe ndi wosamalira chilengedwe komanso wokhazikika kuposa chingwe cha netiweki cha mkuwa; nthawi yomweyo, uli ndi mphamvu yayikulu, kukana dzimbiri, komanso moyo wautumiki wa zaka zoposa 30.
Kwa ogwiritsa ntchito, FTTR idzakhala njira yothandiza yopezera ntchito zosiyanasiyana komanso zokonzedwa bwino za ntchito zapaintaneti zapakhomo, kumanga dzina la netiweki yapakhomo, ndikuwonjezera ARPU ya ogwiritsa ntchito; iperekanso njira zofunikira pakukulitsa nyumba zanzeru komanso chithandizo chatsopano chogwirizana. Kuphatikiza pa kugwiritsa ntchito pazochitika zapaintaneti zapakhomo, FTTR ndi yoyenera kwambiri panyumba zamabizinesi, mapaki ndi zochitika zina zapaintaneti zamakampani am'deralo, zomwe zingathandize ogwiritsa ntchito kufalikira kuchokera pamaneti ambiri kupita kumaneti am'deralo kuti akhazikitse kukhulupirika kwa ogwiritsa ntchito makampani.
FTTR yafika
Ndi chitukuko chachangu cha netiweki ya kuwala ku China komanso kukhwima kwa unyolo wa mafakitale, FTTR siili patali, ikuonekera.
Mu Meyi 2020, Guangdong Telecom ndi Huawei adayambitsa limodzi njira yoyamba padziko lonse lapansi ya FTTR all-optical home network, yomwe yakhala chizindikiro chofunikira cha "kusintha" kwachiwiri kwa kusintha kwa kuwala ndi poyambira pakukula kwa ntchito zapaintaneti zapakhomo. Mwa kuyika ulusi wa kuwala mchipinda chilichonse ndikuyika Wi-Fi 6 optical network unit ndi set top box, imatha kuthandizira ma network apamwamba 1 mpaka 16, kuti aliyense m'banjamo, m'chipinda chilichonse, komanso nthawi iliyonse akhale ndi chidziwitso cha super gigabit Broadband.
Pakadali pano, yankho la FTTR lozikidwa pa ukadaulo wa PON latulutsidwa m'mabizinesi ndi ogwira ntchito m'maboma ndi mizinda 13 kuphatikiza Guangdong, Sichuan, Tianjin, Jilin, Shaanxi, Yunnan, Henan, ndi zina zotero, ndipo ogwira ntchito m'maboma ndi mizinda yoposa 30 amaliza pulogalamu yoyesera komanso gawo lotsatira lokonzekera.
Motsogozedwa ndi "Dongosolo la Zaka Zisanu la 14", "zomangamanga zatsopano" ndi mfundo zina zabwino, komanso kufunikira kwa msika kwa ogula kunyumba konse "kuchokera pazabwino kupita pazabwino" ndi "kuchokera pazabwino kupita pazabwino", akuyembekezeka kuti FTTR idzakhalapo m'zaka zisanu zikubwerazi. Idzalowa m'mabanja 40% ku China, ipitiliza kulimbikitsa chitukuko chapamwamba cha "Broadband China", kutsegula malo amsika a mazana mabiliyoni, ndikuyendetsa kukula kwa mataniliyoni a mapulogalamu a digito ndi makampani anzeru kunyumba.
