Nekunyorwa kwe "Gigabit Optical Network" mumushumo webasa rehurumende kekutanga, uye kuda kuri kuwedzera kwevatengi kwemhando yekubatanidza, "chimurenga" chechipiri che "optical reform" munhoroondo yebroadband yenyika yangu chiri kutanga.
Mumakore gumi apfuura, vashandi vekuChina vakachinja waya dzemhangura dzinopinda mumba dzinoita optical fiber (FTTH) kwemakore anopfuura zana, uye nekuda kweizvi, vakazadzisa zvizere masevhisi eruzivo rwepamusoro-soro kumhuri, uye vakapedzisa shanduko yekutanga ye optical. "Revolution" yakaisa hwaro hwesimba re network. Mumakore gumi anotevera, fiber ye all-optical (FTTR) ye networking yepamba ichave nzira itsva uye kudhonza. Nekuunza gigabit mukamuri rega rega, ichagadzira masevhisi eruzivo rwepamusoro-soro akatarisana nevanhu nema terminals, uye kupa ruzivo rwepamusoro-soro rweBroadband ruchawedzera kukurumidzisa kuvaka kwe network power uye digital economy.
Maitiro akajairika ekuwana gigabit kumba
Senzira huru yenyika iri kuramba ichiwedzera kushandiswa kwedhijitari, basa guru reBroadband muhupfumi hwevanhu riri kuramba richikura. Tsvagiridzo yakaitwa neWorld Bank inoratidza kuti kuwedzera kwe10% kwekushandiswa kweBroadband kuchasimudzira kukura kweGDP kweavhareji ye1.38%; "White Paper on China's Digital Economy Development and Employment (2019)" inoratidza kuti network yeChina yemagetsi emagetsi emagetsi emagetsi emagetsi emagetsi emagetsi emamiriyoni zana nemakumi masere inotsigira 31.3 trillion yuan muhupfumi hwedhijitari. Nekuuya kwenguva yeF5G all-optical, broadband iri kutarisanawo nemikana mitsva yekuvandudza.
Gore rino, zvinokurudzirwa "kuwedzera kuvakwa kwema network e5G uye ma network e gigabit optical, uye kuwedzera mamiriro ekushandisa"; panguva imwe chete, "Chirongwa chemakore mashanu chegumi nemana" chinotaurawo nezve "kusimudzira nekuvandudza ma network e gigabit optical fiber." Kukurudzira ma network e broadband access kubva pa 100M kuenda ku Gigabit kwave chirongwa chakakosha padanho renyika.
Kumhuri, kuwana gigabit ndiyo nzira yakajairika. Denda idzva rekorona rakangoerekana rakonzera kukura kukuru kwemabhizinesi matsva nemamodeli matsva. Mhuri haisisiri nzvimbo yehupenyu chete. Panguva imwe chete, inewo hunhu hwemagariro evanhu hwakadai sezvikoro, zvipatara, mahofisi, uye ma theatre, uye yave nzvimbo yekubudirira chaiyo. Uye home broadband ndiyo nzira huru inokurudzira kuwedzera hunhu hwemagariro evanhu hwemhuri.
Asi panguva imwe chete, maapplication matsva akawanda ekubatanidza ruzivo akaunza matambudziko mazhinji kubroadband kumba. Semuenzaniso, pandinoona nhepfenyuro dziri mhenyu, makirasi epamhepo, uye misangano yepamhepo, ndinowanzo sangana nekugunun'una, maframe akadonha, uye audio nemavhidhiyo zvisina kuenderana. Mhuri dze100M zvishoma nezvishoma hadzina kukwana. Kuti tiwedzere ruzivo rwevatengi online uye pfungwa yekutenga, zvinokurumidzira kushanduka kuenda kugigabit bandwidth, uye kutoramba tichiita budiriro muhukuru hwekunonoka, chiyero chekurasikirwa kwepaketi, uye huwandu hwekubatana.
Kutaura zvazviri, vatengi pachavo vari "kuvhota netsoka dzavo" - nekutanga kwemabasa eGigabit Broadband nevashandi mumapurovhinzi akasiyana-siyana, vanyoreri veGigabit vemunyika yangu vapinda munguva yekukura nekukurumidza mugore rapfuura. Nhamba dzinoratidza kuti pakupera kwa2020, huwandu hwevashandisi veGigabit munyika yangu hwava pedyo nemamiriyoni 6.4, nekukura kwegore negore kwe700%.
FTTR: Kutungamira "chimurenga" chechipiri chekuchinja kwechiedza
Pfungwa yekuti "Kamuri rega rega rinogona kuwana ruzivo rweGigabit service" inoita seiri nyore, asi yakaoma. Nzira yekutumira data ndiyo inonyanya kukanganisa tekinoroji yekubatanidza mawebhusaiti kumba. Parizvino, mwero wezviyero zveWi-Fi relay, PLC power modems, uye network cables zvinonyanya kukwira kusvika 100M. Kunyangwe mitsara mishanu yepamusoro haigone kusvika gigabit. Mune ramangwana, ichashanduka kuita mitsara yeCategory 6 ne7.
Saka, mumakore achangopfuura, indasitiri iyi yave ichinyanya kukoshesa fiber ye optical. Mhinduro yeFTTR gigabit all-optical room networking solution yakavakirwa paPON technology architecture ndiyo mhinduro yepamusoro ye networking kumba, ichitarisira kupa dzidzo online, online office, uye live broadcast. Masevhisi matsva akadai se cargo, e-sports varaidzo, uye whole-house intelligence kuti uwane ruzivo rwepamusoro-soro rwe broadband. Nyanzvi yepamusoro yeindasitiri yakaratidza kuC114 kuti, "Chinhu chikuru chekuona kugona kwebandwidth i frequency hunhu hwe transmission medium. Frequency hunhu hwe optical fibers hwakapetwa makumi ezviuru kupfuura hwe network cables. Hupenyu hwe tekinoroji hwe network cables hwakaganhurirwa, nepo hupenyu hwehunyanzvi hwe optical fibers husina muganho. Tinofanira kutarisa dambudziko kubva pakuona kwekuvandudza."
Zvikuru, mhinduro yeFTTR ine hunhu huna hukuru: kukurumidza kumhanya, mutengo wakaderera, kugadziriswa kuri nyore, uye kuchengetedzwa kwezvakatipoteredza kwakasvibirira. Chekutanga, fiber yemaziso inozivikanwa senzira inokurumidza kutumirwa. Tekinoroji yekutengeserana iripo inogona kuwana kugona kwekutumira kwemazana eGbps. Mushure mekunge fiber yaiswa mumba mese, hapana chikonzero chekuchinja mitsetse yekuvandudza mune ramangwana kuenda kune network ye10Gbps 10G, iyo inogona kunzi ndeye kamwe chete. Chechipiri, indasitiri yefiber yemaziso yakura uye musika wagadzikana. Mutengo wepakati wakaderera pane 50% yetambo yenetwork, uye mutengo wekushandura wakadererawo.
Chechitatu, huwandu hwefiber ye optical hunongova 15% chete yetambo ye network yakajairika, uye idiki uye iri nyore kugadzirazve kuburikidza nepombi. Inotsigira fiber ye optical yakajeka, uye mutsetse wakavhurika haukuvadzi kushongedza, uye kugamuchirwa kwemushandisi kwakanyanya; kune nzira dzakawanda dzekuisa, dzisingarambidzwe nemhando dzeimba itsva nedzekare, uye nzvimbo yekushandisa yakakura. Chekupedzisira, zvinhu zve fiber ye optical ijecha (silica), iro rinodzivirira nharaunda uye rinogara kwenguva refu kupfuura tambo ye network ye copper; panguva imwe chete, ine simba guru, inodzivirira ngura, uye hupenyu hwebasa hweanopfuura makore makumi matatu.
Kune vanofambisa, FTTR ichave nzira inoshanda yekuwana mashandiro akasiyana uye akagadziridzwa emasevhisi epamusha ebroadband, kuvaka rudzi rwe network yepamba, uye kuwedzera ARPU yevashandisi; ichapawo nzira dzinodiwa dzekuvandudza dzimba dzakangwara uye rutsigiro rutsva rwehupfumi hwakabatana. Kuwedzera kune mashandisirwo muzviitiko zve network yepamba, FTTR yakakodzerawo zvivakwa zvemabhizinesi, mapaki nedzimwe nzvimbo dze network yemakambani, izvo zvinogona kubatsira vanofambisa kubva kuma network enzvimbo yakakura kuenda kuma network enzvimbo kuti vasimbise kubatana nevashandisi vemakambani.
FTTR yasvika
Nekukura nekukurumidza kwenetwork ye optical yeChina uye kukura kwecheni yemaindasitiri, FTTR haisi kure, yava kuonekwa.
Muna Chivabvu 2020, Guangdong Telecom neHuawei vakaparura pamwe chete mhinduro yekutanga yepasi rose yeFTTR all-optical home network, iyo yave chiratidzo chakakosha che "revolution" yechipiri yekuchinja kwe optical uye nzvimbo itsva yekutanga yekuvandudza masevhisi e broadband epamba. Nekuisa fibers dze optical mukamuri rega rega uye kuisa Wi-Fi 6 optical network unit uye set top box, inogona kutsigira 1 kusvika 16 super networking, kuitira kuti munhu wese mumhuri, mukamuri rega rega, uye panguva yega yega ave neruzivo rwe super gigabit Broadband.
Parizvino, mhinduro yeFTTR yakavakirwa patekinoroji yePON yakaburitswa mukutengeserana nevanoshanda mumatunhu gumi nematatu nemaguta anosanganisira Guangdong, Sichuan, Tianjin, Jilin, Shaanxi, Yunnan, Henan, nezvimwewo, uye vanoshanda mumatunhu anopfuura makumi matatu nemaguta vapedza chirongwa chekuedza uye danho rinotevera rekuronga.
Zvichitungamirirwa ne "Chirongwa cheMakore Mashanu chegumi nemana", "zvivakwa zvitsva" uye mamwe maitiro akanaka, pamwe nekudiwa kwemusika kweruzivo rwevatengi kumba "kubva pane zvakanaka kuenda pane zvakanaka" uye "kubva pane zvakanaka kuenda pane zviri nani", zvinotarisirwa kuti FTTR ichavepo mumakore mashanu anotevera. Ichapinda mu40% yemhuri muChina, icharamba ichisimudzira kukura kwemhando yepamusoro kwe "Broadband China", ichavhura nzvimbo yemusika yemazana emabhiriyoni, uye ichasimudzira kukura kwematriyoni emashandisirwo edhijitari uye indasitiri yedzimba dzakangwara.
Shenzhen HUANET Technology CO., Ltd. Inopawo GPON OLT, ONU uye PLC Splitter kune vanoshanda mumapurojekiti akawanda.
