Nhau Dzepasi Pose dzeKutaurirana (CWW) Pamusangano weChina Optical Network wegore ra2023 wakaitwa musi wa14-15 Chikumi, Mao Qian, mupi wezano weCommunication Science and Technology Committee yeMinistry of Industry and Information Technology, director weAsia-Pacific Optical Communication Committee, uye pamwe chete nasachigaro weChina Optical Network Seminar. Zvinotaurwa kutixPONParizvino ndiyo mhinduro huru yekuwana Gigabit/10 Gigabit kumba.
PON 10 Gigabit yekupinda pamba
Data rinoratidza kuti kusvika pakupera kwaKubvumbi 2023, huwandu hwese hwevashandisi veInternet fixed broadband munyika yangu hwasvika mamiriyoni 608, uye huwandu hwese hwevashandisi veFTTH vanosvika optical fiber hwasvika mamiriyoni 580, zvichireva 95% yehuwandu hwese hwevashandisi veFixed Broadband; vashandisi veGigabit vasvika mamiriyoni 115. Pamusoro pezvo, huwandu hwemaports efiber access (FTTH/O) hwasvika mabhiriyoni 1.052, zvichireva 96% yemaports eInternet broadband, uye huwandu hwemaports e10G PON ane Gigabit network service capabilities hwasvika mamiriyoni 18.8. Zvinogona kuonekwa kuti network infrastructure yenyika yangu iri kuramba ichikura, uye dzimba nemabhizinesi akawanda asvika pakumhanya kwegigabit network.
Zvisinei, sezvo mararamiro ari kuramba achivandudzwa uye achiwedzera kuva akangwara, hofisi/misangano/kudyidzana kwebasa online/kutenga online/hupenyu/kudzidza zvichave nezvido zvepamusoro zvemhando yebasa re network, uye vashandisi vacharamba vaine zvinodiwa zvepamusoro zvekumhanya kwe network. Wedzera zvimwe zvinotarisirwa. "Saka zvichiri kudikanwa kuti tirambe tichiwedzera mwero wekuwana, uye tizadzise 10G"," akadaro Mao Qian.
Kubudirira1G/10 Kupinda kweGigabit pamba pamwero mukuru, kwete cheteEPON neGPONHazvina kukwana, asiwo kufukidzwa kwe10GEPON neXGPON hakuna kukwana, uye kushanda zvakanaka kwakaderera. Saka, PON inokurumidza zvikuru inodiwa, uye kushanduka kuenda ku50G PON kana kunyange 100G PON chinhu chinofanira kuitwa. Sekureva kwaMao Qian, tichitarisa kubva padanho riripo rekuvandudza, indasitiri iyi inonyanya kushandisa 50G PON imwe chete, iyo inotsigira matekinoroji akasiyana-siyana e10G broadband. Vatengesi vakuru vekutaurirana kwemumba vatova ne50G PON, uye vamwe vatengesi vakatowanawo 100G PON, zvichipa mamiriro ekutanga e10G yekuwana kumba.
Achitaura nezve tekinoroji yeGigabit ne10 Gigabit home access zvakadzama, Mao Qian akati pakutanga kwe2017 Shenzhen Optical Expo, akange akurudzira kusanganiswa kwe passive optical network ne active optical network. Mushure mekunge access rate inodiwa nemushandisi mumwe chete yawedzera kusvika padanho rakati (semuenzaniso, inopfuura 10G), active optical network inogona kunge iri nyore, iri nyore kusimudzira uye inodhura zvishoma pane passive optical network kuti ipe mitengo yakakwira; paShenzhen Optical Expo muna 2021 PaOptiNet, akatokurudzira kuti vashandisi vane bandwidth ye10 Gigabit zvichikwira vanofanira kufunga nezvechirongwa che exclusive bandwidth; paOptiNet muna 2022, akakurudzira kuti exclusive bandwidth inogona kushandiswa nenzira dzakasiyana-siyana: exclusive bandwidth yeXG/XGS-PONvashandisi, P2P optical fiber chete, NG-PON2 wavelength chete, nezvimwewo.
"Zvino zvinoita sekunge chirongwa che exclusive wavelength chine zvakanakira zvakawanda pamutengo uye tekinoroji, uye chichava chiitiko chekuvandudza. Ehe, zvirongwa zvakasiyana-siyana zve bandwidth exclusive zvine zvazvakanakira nezvazvakaipira, uye unogona kusarudza zvichienderana nemamiriro emuno." Mao Qian akadaro.
