Marka la eego kuwa caadiga ah, isdhexgalkaShabakadda saddex-ciyaareedkamacneheedu waxa weeye in saddexda shabakadood ee waaweyn ee isgaadhsiinta, shabakada kombuyuutarka iyo shabakada TV-ga cable ay bixin karaan adeegyo isgaarsiineed oo dhamaystiran oo ay ku jiraan codka, xogta iyo sawirada iyada oo loo marayo isbeddelka farsamada.Sanhe waa erey ballaadhan oo bulsho.Marxaladda hadda la joogo, waxay tilmaamaysaa "dhibic" gudbinta baahinta "wejiga", "dhibcaha" gudbinta isgaadhsiinta "dhibic", iyo kombuyuutarka Isku-dhafka waqtiga-beddelka ee kaydinta shabakada si loogu adeego bini'aadamka macnaheedu maaha isdhexgalka jireed ee saddexda shabakadood ee waaweyn ee shabakadaha isgaarsiinta, shabakadaha kombuyuutarka, iyo shabakadaha telefishinka ee cable, laakiin inta badan waxaa loola jeedaa isdhexgalka codsiyada ganacsiga heerka sare ah.Ka dib "is-dhexgalka Shabakadda Triple-play", dadku waxay isticmaali karaan kantaroolka fog ee TV-ga si ay u soo wacaan, u daawadaan riwaayadaha TV-ga ee telefoonadooda gacanta, dooro shabakadaha iyo terminalka haddii loo baahdo, iyo dhamaystirka isgaarsiinta, TV, iyo helitaanka internetka iyagoo si fudud u jiidaya khadka ama marinka wireless-ka.
Saddex jaranjaro ee Horumarinta FTTx
Horumarinta FTTx ee Shiinaha ayaa soo martay saddex marxaladood.Marxaladda koowaad waa laga bilaabo 2005 ilaa 2007. Marxaladdan ayaa iska leh marxaladda tijaabada.Sannadkii 2005, Shiinaha Telecom waxay EPON ka bilowday tijaabooyinka fiber-ilaa-guriga ee Beijing, Guangzhou, Shanghai, iyo Wuhan si loo xaqiijiyo qaan-gaadhnimadaEPONnidaamka iyo sahamin waayo-aragnimada dhismaha.Muddadan, China Netcom, China Mobile, iwm. waxay sameeyeen tijaabooyin iyo codsiyo tijaabo ah oo ku saabsan nidaamka PON.Miisaanka dhismaha FTTx marxaladan waa mid aad u yar.
Wajiga labaad waxa uu ahaa 2008 ilaa 2009, kaas oo ah waji ciidan oo baaxad leh.Kadib wajigii koowaad ee tijaabada iyo cilmi baarista.Shirkadda Shiinaha Telecom waxay aqoonsatay qaan-gaadhnimada iyo waxqabadka nidaamka EPON, isla markaana waxay sahamisay nooc ka mid ah qaababka dhismaha ee FTTx, waxaana la sameeyay moodooyinka dhismaha ee FTTH/FTTB+LAN/FTTB+DSL.Waxaa ka sii muhiimsan, qiimaha sarreeya ee fiilooyinka naxaasta ah ee wakhtigaas, kharashka qaabka dhismaha FTTB wuxuu lahaa faa'iido weyn marka loo eego kharashka dhismaha ee dhejinta fiilooyinka copper.Baaxadda iyo baaxadda shabakadda FTTB ayaa ka fiicnayd tan shabakadda gelitaanka fiilada copper.Sidaa darteed, dhamaadkii 2007, China Telecom waxay go'aansatay in ay qaadato FTTB + LAN si ballaaran loo geeyo goobaha cusub ee magaalada, in la sameeyo FTTB + DSL wax soo saarka indhaha iyo isbeddelka wax soo saarka naxaasta ee goobaha hadda jira, oo gebi ahaanba la joojiyo dhigista shabakadaha cable copper cusub.Marxaladdan, daad-gureynta ballaaran ee FTTB waxaa sabab u ah waxqabadka qiimaha wanaagsan.
Marxaladda saddexaad waxay bilaabatay 2010, FTTx waxay gashay marxalad cusub oo horumarineed.Bilowgii 2010, Ra'iisul Wasaaraha Wen Jiabao oo ka tirsan Golaha Gobolka ayaa shir guddoominayay shirka fulinta ee Golaha Gobolka, wuxuuna go'aansaday in la dardargeliyo isku xirka shabakadaha isgaarsiinta, shabakadda raadiyaha iyo telefishinka iyo internetka.Waxa loo baahan yahay in la dedejiyo dhismaha shabakada Internet-ka ee fiber-optic-ga iyo is-beddelka labada dhinac ee idaacadaha iyo telefishannada, isgaadhsiinta iyo idaacadaha iyo telefishannada waa in ay suuqyadooda isu furaan oo ay si macquul ah u tartamaan."Isdhexgalka ciyaarta saddex-geesoodka ah" waxay soo bandhigtay tartameyaal cusub iyo goobo cusub oo tartan ah dhammaan warshadaha isgaarsiinta.
Bishii Abriil, 7 wasaaradood iyo guddiyo ay ka mid yihiin Wasaaradda Warshadaha iyo Tignoolajiyada Warfaafinta iyo Komishanka Horumarinta iyo Dib-u-habaynta Qaranka ayaa si wada jir ah u soo saaray “Ra’yiga Kor-u-qaadista Dhismaha Isku-xidhka Fiber Broadband-ka ee Optical Fiber Broadband”, taasoo looga baahan yahay hawl-wadeennada isgaadhsiinta inay dardar-geliyaan dhismaha fiber-bandhereedka indhaha. iyo in la dedejiyo hirgelinta fibre optic broadband ee magaalooyinka iyo tuulooyinka dhulka miyiga ah."Ra'yiga" waxay soo jeedinayaan in sanadka 2011, tirada dekedaha fiber optic fiber-ka ah ay kor u dhaafi doonaan 80 milyan, celceliska awoodda isticmaaleyaasha magaaladu waxay gaari doontaa in ka badan 8 Mbit/s, celceliska awoodda isticmaaleyaasha miyigu waxay gaari doontaa in ka badan 2 Mbit /s, iyo celceliska awoodda gelitaanka ee isticmaalayaasha dhismaha ganacsiga waxay asal ahaan gaari doonaan in ka badan 100 Mbit/s.kartida wax gelinta.3 sano gudahood, maalgelinta dhismaha shabakad ballaadhan ee fiber optic-ga waxay dhaafi doontaa 150 bilyan yuan, tirada isticmaaleyaasha cusub ee broadband waxay dhaafi doontaa 50 milyan.
Marka lagu daro qorshaha dhismaha ee NGB ee uu horay u siidaayay Maamulka Gobolka ee Raadiyaha, Filimada iyo Telefishinada, baaxada baaxada ee guri kasta waxaa looga baahan yahay in uu gaaro 40Mbit/s.Tartanka ay soo bandhigtay "saddex-ciyaarood" ayaa si tartiib tartiib ah diiradda u saaray tartanka helitaanka bandwidth.Hawl wadeenada isgaarsiinta iyo raadiyaha iyo telefishinada ayaa si wada jir ah u qaatay FTTx sida tignoolajiyada la door biday ee dhismaha shabakada xawaaraha sare leh.Tani waxay ka dhigaysaa horumarinta FTTx isbeddelka qiimaha qiimaha una beddelo qodobka tartanka suuqa.Horumarinta FTTx waxay gashay marxalad cusub.
Marka laga eego dhinaca kale, waxay si sax ah u tahay sababtoo ah baaxadda ballaaran iyo bacriminta FTTx ee Shiinaha in waddanku aaminsan yahay in laga eego dhinaca tignoolajiyada iyo silsiladda warshadaha, waxaa jira saldhig farsamo iyo qalab si loo dardargeliyo "isku-dhafka shabakadaha saddex-geesoodka ah. ”.Iyada oo ku saleysan baahida loo qabo ballaarinta baahida gudaha iyo kor u qaadida heerka tignoolajiyada macluumaadka ee dalkayga, waddanku wuxuu daah-furay istiraatiijiyadda qaran ee "is-dhexgalka Shabakadda Triple-play" waqtigeeda.Waxaa la dhihi karaa waxaa jira xiriir dhow oo isku xiran oo u dhexeeya horumarinta warshadaha FTTx ee Shiinaha iyo istiraatiijiyadda qaranka ee "isdhexgalka Shabakadda Triple-play".
"Ciyaarta saddexleyda ah" waxay kicisaa fikradaha horumarinta FTTx
Fiber-ilaa-xFTTx) helitaanka fiber-ka (FTTx, x = H guriga, P dhismaha, C ee xannibaadda iyo N ee noodhka ama xaafadda) halka fiber FTTH ee guriga, FTTP fiber dhismaha, FTTC fiber ilaa waddada / bulshada, FTTN fiber to noodhka.Fiber-to-the-home (FTTH) waxay ahayd riyo iyo jihayn tignoolajiyadeed oo ay dadku ku raad-joogeen muddo 20 sano ah, laakiin caqabadaha xagga kharashka, tignoolajiyada, iyo baahida awgeed, weli si ballaadhan looma horumarin oo looma horumarin.Si kastaba ha ahaatee, horumarkan gaabiska ah ayaa beryahan dambe si weyn isu bedelay.Taageerada siyaasadda iyo horumarinta tignoolajiyada awgeed, FTTH waxay mar kale noqotay meel kulul ka dib sannado badan oo aamusnaan ah, oo gashay xilli horumar degdeg ah.Raaxada iyo raaxaysiga nolosha ee ay keeneen codsiyo ballaadhan oo kala duwan oo la xidhiidha sida VoIP, ciyaarta-online, E-learning, MOD (Multimedia on Demand) iyo guriga smart, iyo daawashada sare ee isdhexgalka ee uu sababay HDTV Kacaanku wuxuu sameeyay fiber indhaha. oo leh sifooyin aad u fiican sida xajmigu sareeyo, awood weyn, iyo khasaaro hoose waa doorasho lama huraan u ah dhexdhexaadinta xogta u gudbisa macmiilka.Sababtan awgeed, dad badan oo caqli-gal ah ayaa u fiirsada FTTx (gaar ahaan fiber-to-guri iyo fiber-to-the-guri) inay tahay meel muhiim ah oo ka soo kabashada suuqa isgaarsiinta indhaha.Waxaana la filayaa in dhowrka sano ee soo socda, shabakadda FTTH ay yeelan doonto horumar weyn.
Shiinaha Telecom waxay qorsheyneysaa inay dhisto 1 milyan oo shabakadood oo FTTH ah sanadka 2010. Beijing, Shanghai, Jiangsu, Zhejiang, Guangdong, Wuhan iyo gobolada kale iyo magaalooyinka ayaa sidoo kale si isdaba joog ah u soo jeediyay adeegyo xawaarihiisu sarreeyo sida helitaanka 20Mbit/s.Waxaa la saadaalin karaa in qaabka dhismaha ee FTTH (fiber-to-the-guri) uu noqon doono qaabka dhismaha FTTx ee caadiga ah laga bilaabo 2011 wixii ka dambeeya.Miisaanka warshadaha FTTx ayaa sidoo kale ballaarin doona si waafaqsan.Hawl-wadeennada raadiyaha iyo telefishinka, ka dib "is-dhexgalka saddexda shabakad", sida ugu dhakhsaha badan ee loo sameeyo isbeddelka laba-geesoodka ah ee shabakada hadda jirta iyo horumarinta adeegyada cusub sida TV-ga isdhexgalka, helitaanka internetka ee ballaadhan, iyo helitaanka codka ayaa ah mudnaanta koowaad.Si kastaba ha ahaatee, sababta oo ah lacag la'aan, tignoolajiyada, iyo kartida, suurtagal maaha in lacag badan lagu bixiyo si loo dhiso shabakad isgaarsiineed oo tayo sare leh.Waxa kaliya oo aan isticmaali karnaa ilaha shabakada ee jira, taabo awoodaha, oo aan u dhisno si tartiib tartiib ah.
