Mukutaura kwevasina basa, kubatanidzwa kweTriple-kutamba Networkzvinoreva kuti matatu makuru makuru enharembozha network, komputa network uye cable TV network inogona kupa yakazara multimedia kutaurirana masevhisi anosanganisira izwi, data uye mifananidzo kuburikidza neshanduko yetekinoroji. Sanhe ishoko rakakura uye remagariro. Parizvino, inoreva "poindi" mukutepfenyura ku "chiso", iyo "poindi" mukufambiswa kwekukurukurirana kuenda ku "point", uye komputa Kubatanidzwa kwekuchinja-nguva kwekuchengetedza munetiweki kushandira zvirinani vanhu. hazvireve kubatanidzwa kwemuviri kwematatu makuru enharembozha, makomputa network, uye cable terevhizheni network, asi zvinonyanya kureva kubatanidzwa kwepamusoro-level bhizinesi application. Mushure me "kubatanidzwa kweTriple-play Network", vanhu vanogona kushandisa terevhizheni iri kure kufona, kuona madhirama epaTV panharembozha dzavo, kusarudza network nematerminals sezvinodiwa, uye kutaurirana kwakakwana, TV, uye kuwana Internet nekungodhonza line kana wireless access.
Matanho matatu eFTTx Development
Kuvandudzwa kweFTTx yeChina kwapfuura nematanho matatu. Danho rekutanga rinobva muna 2005 kusvika 2007. Danho iri nderechikamu chekuedza. Muna 2005, China Telecom yakatanga EPON fiber-to-the-imba miedzo muBeijing, Guangzhou, Shanghai, uye Wuhan kuratidza kukura kweiyo.EPONsystem uye kuongorora ruzivo rwekuvaka. Munguva iyi, China Netcom, China Mobile, nezvimwewo vakaita bvunzo uye kutyaira zvikumbiro paPON system. Chiyero chekuvaka cheFTTx panguva ino idiki kwazvo.
Chikamu chechipiri chinobva muna 2008 kusvika muna 2009, chinova chikamu chikuru chekuendesa. Mushure mechikamu chekutanga chekutyaira nekutsvaga. China Telecom yakaziva kukura uye kushanda kweEPON system, uye panguva imwechete yakaongorora seti yeFTTx yekuvaka modhi, uye mhando dzekuvaka dzeFTTH/FTTB + LAN/FTTB + DSL dzakatangwa. Zvinonyanya kukosha, nekuda kwemutengo wepamusoro wetambo dzemhangura panguva iyoyo, mutengo weFTTB wekuvaka modhi waive nemukana wakakura pamusoro pemutengo wekuvaka wekuisa tambo dzemhangura. Iyo bandwidth uye scalability yeFTTB network yaive nani pane iyo yemhangura tambo yekuwana network. Naizvozvo, pakupera kwa2007, China Telecom yakafunga kutora FTTB + LAN kuti iendeswe kunzvimbo dzichangobva kuvakwa dzeguta, kuita FTTB + DSL optical input uye shanduko yekubuda kwemhangura munzvimbo dziripo, uye kumisa zvachose kuiswa. itsva copper cable network. Panguva ino, kutumirwa kukuru kweFTTB kunokonzerwa nekuita kurinani kwemutengo.
Danho rechitatu rakatanga muna 2010, uye FTTx yakapinda muchikamu chitsva chebudiriro. Mukutanga kwa2010, Mutungamiri Wen Jiabao weState Council akatungamira musangano mukuru weState Council uye vakafunga kukurumidza kubatanidza dandemutande rekufambiswa kwemashoko, redhiyo neterevhizheni network neInternet. Zvinodiwa kuti kukurumidze kuvakwa kwefiber-optic Broadband access network uye kushandura nzira mbiri dzeredhiyo neterevhizheni, uye kuti nharembozha neredhiyo neterevhizheni zvinofanirwa kuvhura misika yavo kune mumwe nemumwe uye kukwikwidza zvine musoro. "Kubatanidzwa katatu kwekutamba" kwaunza vakwikwidzi vatsva uye minda mitsva yemakwikwi kune yese telecom indasitiri.
Muna Kubvumbi, mashumiro manomwe nemakomisheni anosanganisira Bazi reIndasitiri neRuzivo rweTekinoroji uye National Development and Reform Commission vakabatana vakapa "Maonero ekusimudzira Kuvakwa kweOptical Fiber Broadband Networks", inoda kuti vafambisi venharembozha vakurumidze kuvakwa kwe optical fiber Broadband, uye nekukasira kushandiswa kwefiber optic Broadband mumaguta nemisha mumaruwa. "Pfungwa" dzinokurudzira kuti ne 2011, nhamba ye optical fiber Broadband ports ichapfuura 80 mamiriyoni, chiyero chekusvika kwevashandisi vemaguta chichasvika kupfuura 8 Mbit / s, chiyero chekusvika kwevashandi vekumaruwa chichasvika kupfuura 2 Mbit. /s, uye avhareji yekuwana mukana wevashandisi vekuvaka vekutengesa vanozowana zvinodarika 100 Mbit/s. kugona kuisa. Mukati memakore matatu, kudyara kwefiber optic Broadband network kuvaka kuchapfuura 150 bhiriyoni yuan, uye huwandu hwevashandisi vebroadband huchapfuura mamirioni makumi mashanu.
Yakasanganiswa nechirongwa chekuvaka cheNGB chakaburitswa kare neHurumende Administration yeRadhiyo, Firimu neTerevhizheni, bandwidth yemba yega yega inodiwa kuti isvike 40Mbit/s. Makwikwi akaunzwa ne "kutamba katatu" zvishoma nezvishoma akatarisa pamakwikwi ekuwana bandwidth. Telecom vanoshanda neredhiyo uye terevhizheni vanoshanda vakabatana vakagamuchira FTTx seyakasarudzika tekinoroji yekukurumidza-kumhanya yekuwana network kuvaka. Izvi zvinoita kuti kusimudzirwa kweFTTx kuchinje kubva pamutengo wechinhu kuenda kumakwikwi emusika chinhu. Kuvandudzwa kweFTTx kwapinda padanho idzva.
Kubva kune imwe nzvimbo yekuona, imhaka yehukuru uye yakakura kutumirwa kweFTTx muChina iyo nyika inotenda kuti kubva pakuona tekinoroji neketani yemaindasitiri, kune hunyanzvi uye hwezvinhu hwaro hwekumhanyisa "triple network kubatanidzwa. ”. Zvichienderana nekudikanwa kwekuwedzera kudiwa kwepamba uye kuwedzera mwero weruzivo rwenyika yangu, nyika yakatanga zano renyika re "kubatanidzwa kweTriple-play Network" nekufamba kwenguva. Zvinogona kutaurwa kuti kune hukama hwakabatana pakati pekuvandudzwa kweindasitiri yeFTTx yeChina uye zano renyika re "kubatanidzwa kweTriple-play Network".
"Kutamba katatu" kunokonzeresa FTTx kuvandudza mazano ekuvandudza
Fiber-to-the-x (FTTx) fibre access (FTTx, x = H yepamba, P yezvivakwa, C yekumisikidza uye N yenode kana nharaunda) uko FTTH faibha kuenda kumba, FTTP faibha kunzvimbo, FTTC faibha kuMugwagwa/nharaunda, FTTN faibha kusvika node. Fiber-to-the-home (FTTH) yanga iri chiroto uye nzira yetekinoroji iyo vanhu vanga vachitevera kwemakore makumi maviri, asi nekuda kwezvipingamupinyi mumutengo, tekinoroji, uye kudiwa, haisati yasimudzirwa zvakanyanya nekuvandudzwa. Zvisinei, uku kunonoka kwekufambira mberi kwakachinja zvikuru munguva pfupi yapfuura. Nekuda kwerutsigiro rwemitemo uye kuvandudzwa kwetekinoroji, FTTH yave zvakare nzvimbo inopisa mushure memakore mazhinji ekunyarara, ichipinda munguva yekukurumidza kusimudzira. Kunyaradza uye kureruka kwehupenyu kwakaunzwa neakasiyana siyana anoenderana Broadband application seVoIP, Online-mutambo, E-kudzidza, MOD (Multimedia on Demand) uye smart imba, uye inopindirana yepamusoro-tsananguro yekuona yakakonzerwa neHDTV Shanduko iyi yagadzira optical fiber. ine hunhu hwakanakisa senge yakakwira bandwidth, hukuru hukuru, uye kurasikirwa kwakaderera sarudzo isingadzivisike yepakati inotumira data kumutengi. Nekuda kweizvi, vanhu vazhinji vanonzwisisa vanoona FTTx (kunyanya fiber-to-the-home uye fiber-to-the-premises) sechinhu chakakosha chekuchinja mukudzoreredza kwemusika wekutaurirana wemaziso. Uye zvinotarisirwa kuti mumakore mashoma anotevera, FTTH network ichave nebudiriro huru.
China Telecom inoronga kuvaka miriyoni imwe yeFTTH network muna 2010. Beijing, Shanghai, Jiangsu, Zhejiang, Guangdong, Wuhan uye mamwe mapurovhinzi nemaguta vakarongawo zvakatevedzana masevhisi e-high-speed broadband akadai se20Mbit/s kuwana. Zvinogona kufanotaurwa kuti iyo FTTH (fiber-to-the-imba) modhi yekuvaka ichave yakajairwa FTTx yekuvaka maitiro kubva 2011 zvichienda mberi. Huyero hweiyo FTTx indasitiri ichawedzerawo zvinoenderana. Kune vatyairi veredhiyo neterevhizheni, mushure me "matatu-network kubatanidzwa", maitiro ekukurumidza kuita maviri-nzira shanduko yeiyo iripo network uye kuvandudza masevhisi matsva akadai seanopindirana TV, Broadband Internet kuwana, uye kuwana izwi ndiyo inonyanya kukosha. Nekudaro, nekuda kwekushaikwa kwemari, tekinoroji, uye matarenda, hazvibviri kushandisa mari yakawanda kuvaka nharembozha yemhando yepamusoro. Tinogona chete kushandisa zviripo network zviwanikwa, tinya zvinogoneka, uye kuvaka zvishoma nezvishoma.
