Mukutaura kwevanhuwo zvavo, kubatanidzwa kweNetwork yekutamba katatuzvinoreva kuti network nhatu huru dze telecommunication network, computer network uye cable TV network dzinogona kupa masevhisi ekukurukurirana emultimedia anosanganisira izwi, data nemifananidzo kuburikidza nekushandura kwetekinoroji. Sanhe izwi rakakura uye remagariro evanhu. Pari zvino, rinoreva "nzvimbo" mukuparadzira nhepfenyuro kuenda ku "chiso", "nzvimbo" mukutumira kutaurirana kuenda ku "nzvimbo", uye komputa. Kubatanidzwa kwekuchengetedza mu network kunochinja-chinja kwenguva hakurevi kubatanidzwa kwe network nhatu huru dze telecommunication networks, computer networks, uye cable television networks, asi zvinonyanya kureva kubatanidzwa kwezvishandiso zvebhizinesi zvepamusoro. Mushure me "kubatanidzwa kweTriple-play Network", vanhu vanogona kushandisa TV remote control kufona, kuona madhirama eTV panharembozha dzavo, kusarudza networks nematerminals sezvinodiwa, uye kutaurirana kwakakwana, TV, uye Internet nekungodhonza tambo kana wireless access.
Makwikwi matatu ekuvandudzwa kweFTTx
Kuvandudzwa kweFTTx yeChina kwapfuura nematanho matatu. Danho rekutanga nderekubva muna 2005 kusvika 2007. Danho iri nderedanho rekuyedza. Muna 2005, China Telecom yakatanga kuyedza EPON fiber-to-the-home muBeijing, Guangzhou, Shanghai, neWuhan kuti ione kuti yakura sei.EPONongorora ruzivo rwekuvaka. Munguva iyi, China Netcom, China Mobile, nezvimwewo zvakaita bvunzo uye mashandisirwo ekuedza paPON system. Huwandu hwekuvaka hweFTTx padanho iri hudiki kwazvo.
Chikamu chechipiri chinotangira muna 2008 kusvika 2009, inova chikamu chikuru chekuisa magetsi. Mushure mechikamu chekutanga chekuedza nekutsvaga, China Telecom yakaona kukura uye kushanda kwehurongwa hweEPON, uye panguva imwe chete yakaongorora seti yemamodheru ekuvaka eFTTx, uye mamodheru ekuvaka eFTTH/FTTB+LAN/FTTB+DSL akaiswa. Chinonyanya kukosha ndechekuti, nekuda kwemutengo wakakwira wetambo dzemhangura panguva iyoyo, mutengo wemodheru yekuvaka yeFTTB waiva nemukana wakakura kupfuura mutengo wekuvaka wekuisa tambo dzemhangura. Kureba kwebandwidth uye kugona kwenetwork yeFTTB zvaive zviri nani pane zvenetwork yekupinda tambo dzemhangura. Saka, pakupera kwa2007, China Telecom yakasarudza kushandisa FTTB+LAN yekuisa magetsi munzvimbo itsva dzeguta, kuita FTTB+DSL optical input uye copper output transformation munzvimbo dziripo, uye kumisa zvachose kuisa manetwork matsva etambo dzemhangura. Padanho rino, kuiswa kweFTTB kukuru kunokonzerwa nekushanda kuri nani kwemari.
Danho rechitatu rakatanga muna 2010, uye FTTx yakapinda padanho idzva rekuvandudzwa. Pakutanga kwa2010, Mutungamiriri Wen Jiabao weDare reHurumende akatungamira musangano wevatungamiriri veDare reHurumende ndokusarudza kukurumidzisa kubatanidzwa kwenetwork yekutaurirana, network yeredhiyo neterevhizheni neInternet. Zvinodiwa kukurumidzisa kuvakwa kwenetwork ye fiber-optic broadband uye kushandurwa kwemanetwork eredhiyo neterevhizheni, uye kuti kutaurirana neredhiyo neterevhizheni zvinofanira kuvhura misika yazvo uye kukwikwidzana zvine musoro. "Kubatanidzwa kwemitambo mitatu" kwakaunza makwikwi matsva neminda mitsva yemakwikwi kuindasitiri yese yenharembozha.
Muna Kubvumbi, maminisitiri manomwe nemakomisheni anosanganisira Ministry of Industry and Information Technology pamwe neNational Development and Reform Commission vakaburitsa pamwe chete "Mazano Ekukurudzira Kuvaka Optical Fiber Broadband Networks", vachida kuti vashandi vemafoni vakurumidze kuvaka optical fiber broadband, uye kukurumidzisa kuiswa kwe fiber optic broadband mumaguta nemisha iri kumaruwa. "Mazano" aya anokurudzira kuti panosvika gore ra2011, huwandu hwemaports e optical fiber broadband huchapfuura mamiriyoni makumi masere, avhareji yekugona kupinda kwevanhu mumaguta ichasvika anopfuura 8 Mbit/s, avhareji yekugona kupinda kwevanhu vekumaruwa ichasvika anopfuura 2 Mbit/s, uye avhareji yekugona kupinda kwevanhu muzvivakwa zvemabhizinesi ichasvika pakugona kupinda kweanopfuura 100 Mbit/s. Mukati memakore matatu, mari inoshandiswa mukuvaka fiber optic broadband network ichapfuura mabhiriyoni zana nemakumi mashanu eyuan, uye nhamba yevashandisi vatsva ve broadband ichapfuura mamiriyoni makumi mashanu.
Pamwe chete nehurongwa hwekuvaka hweNGB hwakaburitswa kare neHurumende yeRadio, Mafirimu neTerevhizheni, bandwidth yekuwana yemba yega yega inodiwa kuti isvike 40Mbit/s. Makwikwi akaunzwa ne "triple play" akanyanya kutarisa pamakwikwi ebandwidth yekuwana. Vashandi veTerevhizheni nevashandi veredhiyo neterevhizheni vakagamuchira FTTx pamwe chete setekinoroji inosarudzwa yekuvaka network yekusvika nekukurumidza. Izvi zvinoita kuti kukura kweFTTx kuchinje kubva pamutengo wezvinhu kuenda pamakwikwi emusika. Kukura kweFTTx kwapinda padanho idzva.
Kubva pane imwe pfungwa, imhaka yekufambiswa kukuru kweFTTx muChina kuti nyika itende kuti kubva pamaonero etekinoroji neindasitiri, kune hwaro hwehunyanzvi uye hwezvinhu zvekusimudzira "kubatanidzwa kwenetwork katatu". Zvichibva pakudiwa kwekuwedzera kudiwa kwemuno uye kusimudzira mwero wetekinoroji yeruzivo yenyika yangu, nyika yakatanga hurongwa hwenyika hwe "kubatanidzwa kweTriple-play Network" munguva yakafanira. Zvinogona kutaurwa kuti pane hukama hwakabatana pakati pekuvandudzwa kweindasitiri yeFTTx yeChina nehurongwa hwenyika hwe "kubatanidzwa kweTriple-play Network".
"Kutamba katatu" kunotanga pfungwa dzekuvandudza dzeFTTx
Fiber-to-the-x (FTTx) kuwana fiber (FTTx, x = H yepamba, P yenzvimbo, C yemuganho uye N yenzvimbo kana nharaunda) uko FTTH fiber kuenda kumba, FTTP fiber kuenda kunzvimbo, FTTC fiber kuenda kuRoadside/community, FTTN fiber kuenda kuNode. Fiber-to-the-home (FTTH) yave iri hope uye nhungamiro yetekinoroji iyo vanhu vanga vachitevera kwemakore makumi maviri, asi nekuda kwezvipingamupinyi mumutengo, tekinoroji, uye kudiwa, haisati yakurudzirwa zvakanyanya uye yakagadziridzwa. Zvisinei, kufamba uku kunonoka kwekufambira mberi kwachinja zvakanyanya munguva pfupi yapfuura. Nekuda kwerutsigiro rwemitemo nekuvandudzwa kwetekinoroji, FTTH yave zvakare nzvimbo inopisa mushure memakore mazhinji ekunyarara, ichipinda munguva yekukura nekukurumidza. Kunyaradzwa uye nyore kwehupenyu kunounzwa nemashandisirwo akasiyana-siyana ane chekuita nebroadband akadai seVoIP, Online-game, E-learning, MOD (Multimedia on Demand) uye smart home, uye kuona kwemhando yepamusoro kunokonzerwa neHDTV. Kuchinja uku kwakaita kuti optical fiber ine hunhu hwakanaka senge high bandwidth, kugona kukuru, uye kurasikirwa kwakaderera ive sarudzo isingadzivisike yechinhu chinotumira data kumutengi. Nekuda kweizvi, vanhu vazhinji vane ruzivo rwakawanda vanoona FTTx (kunyanya fiber-to-the-home uye fiber-to-the-placemises) senzvimbo yakakosha yekuchinja mukuvandudzwa kwemusika wekutaurirana kwemaziso. Uye zvinotarisirwa kuti mumakore mashoma anotevera, network yeFTTH ichave nekukura kukuru.
China Telecom inoronga kuvaka network dze FTTH dzinosvika miriyoni imwe muna 2010. Beijing, Shanghai, Jiangsu, Zhejiang, Guangdong, Wuhan nedzimwe matunhu nemaguta zvakaratidzawo masevhisi e broadband anomhanya zvakanyanya akadai se 20Mbit/s access. Zvinogona kufanotaurwa kuti FTTH (fiber-to-the-home) construction mode ichave nzira huru yekuvaka FTTx kubva muna 2011 zvichienda mberi. Kukura kweindasitiri yeFTTx kuchawedzerawo zvinoenderana. Kune vanoshanda neredhiyo neterevhizheni, mushure me "three-network integration", maitiro ekukurumidza kuita shanduko mbiri dzenetwork iripo nekugadzira masevhisi matsva akadai se interactive TV, broadband Internet access, uye voice access ndiyo inonyanya kukosheswa. Zvisinei, nekuda kwekushaikwa kwemari, tekinoroji, uye matarenda, hazvigoneke kushandisa mari yakawanda kuvaka network yekukurukurirana yepamusoro. Tinogona kungoshandisa zviwanikwa zve network zviripo, kushandisa potentials, uye kuvaka zvishoma nezvishoma.
