Communication World News (CWW) Pa2023 China Optical Network Semina yakaitwa muna Chikumi 14-15, Mao Qian, chipangamazano weCommunication Science neTekinoroji Committee yeBazi reIndasitiri neRuzivo rweTekinoroji, director weAsia-Pacific Optical Communication Committee, uye co-sachigaro weChina Optical Network Semina Zvinotaridzwa kutixPONparizvino ndiyo mhinduro huru yeGigabit/10 Gigabit yekuwana imba.
PON 10 Gigabit yekuwana imba
Data inoratidza kuti pakupera kwaKubvumbi 2023, huwandu hwese hwevashandisi veInternet yakatarwa Broadband kupinda munyika yangu i608 miriyoni, iyo iyo yakazara nhamba yevashandisi veOptical fiber kuwana FTTH yasvika 580 miriyoni, inoverengera 95% yehuwandu. nhamba yevashandisi vebroadband vakagadziriswa; vashandisi vegigabit vasvika 115 miriyoni. Pamusoro pezvo, nhamba yefiber access (FTTH/O) ports yakasvika 1.052 bhiriyoni, inoverengera 96% yeInternet Broadband access ports, uye nhamba ye10G PON ports ine Gigabit network service kugona yakasvika 18.8 miriyoni. Zvinogona kuonekwa kuti hupfumi hwenyika yangu huri kuramba huchikura, uye dzimba dzakawanda uye mabhizinesi asvika pakumhanya kwegigabit network.
Zvisinei, sezvo mararamiro anoramba achivandudza uye anowedzera kungwara, hofisi yepaIndaneti / musangano / kudyidzana kwebasa / kutenga paIndaneti / hupenyu / kudzidza kuchava nepamusoro pezvinodiwa zvehutano hwebasa retiweki, uye vashandisi vacharamba vaine zvinodiwa zvepamusoro zvekumhanya kwetiweki. Simudza zvimwe tarisiro. "Saka zvichiri kukosha kuti urambe uchiwedzera huwandu hwekuwana, uye kuziva gumiG, "Mao Qian akadaro.
Kubudirira1G/10 Gigabit imba yekupinda pamwero mukuru, kwete cheteEPON uye GPONhavana kukwanisa, asiwo kufukidzwa kwe10GEPON uye XGPON haina kukura zvakakwana, uye kushanda kwakaderera. Nokudaro, PON yepamusoro-soro inodiwa, uye kushanduka kusvika ku50G PON kana kunyange 100G PON inofanirwa Nzira isingadzivisiki. Sekureva kwaMao Qian, tichitarisa kubva kune yazvino budiriro maitiro, iyo indasitiri inonyanya kurerekera kune imwe-wavelength 50G PON, iyo inotsigira akasiyana matekinoroji e10G Broadband. Mainstream vatengesi vekutaurirana kwepamba vatove nekwaniso ye50G PON, uye vamwe vatengesi vaonawo 100G PON, ichipa mamiriro ekutanga e10G yekuwana imba.
Achitaura nezve tekinoroji yeGigabit uye gumi Gigabit yekuwana imba zvakadzama, Mao Qian akataura kuti pakutanga kwe2017 Shenzhen Optical Expo, akange akurudzira kusanganiswa kwepassive optical network uye inoshanda yekuona network. Mushure mekunge chiyero chekuwana chinodiwa nemushandisi mumwe chete chinowedzera kune imwe nhanho (somuenzaniso, yakakura kupfuura 10G), iyo inoshanda optical network inogona kunge iri nyore, nyore kusimudzira uye yakaderera mutengo pane passive optical network kuti ipe mazinga akakwirira; paShenzhen Optical Expo muna 2021 PaOptiNet, akatokurudzira kuti vashandisi vane bandwidth ye10 Gigabit uye pamusoro vanofanira kufunga nezvechirongwa chega bandwidth; paOptiNet muna 2022, akakurudzira kuti yakasarudzika bandwidth inogona kuitwa nenzira dzakasiyana siyana: yakasarudzika bandwidth ye.XG/XGS-PONvashandisi, P2P optical fiber yakasarudzika, NG-PON2 wavelength yakasarudzika, nezvimwe.
"Zvino zvinoita sekunge chirongwa chewavelength chakasarudzika chine mutengo wakawanda uye zvakanakira tekinoroji, uye ichave maitiro ebudiriro. Ehe, akasiyana bandwidth zvirongwa zvega zvine zvazvakanakira uye zvazvakaipira, uye unogona kusarudza zvinoenderana nemamiriro enzvimbo. " Mao Qian akadaro.
