Iindaba zeHlabathi zoNxibelelwano (CWW) KwiSemina ye-2023 ye-China Optical Network eyayibanjwe ngoJuni 14-15, uMao Qian, umcebisi weNzululwazi yezoNxibelelwano kunye neKomiti yeTekhnoloji yeSebe lezoShishino kunye neTeknoloji yoLwazi, umlawuli we-Asia-Pacific Optical Communication Committee, kunye no-co-sihlalo we-China Optical Network Semina Kucaciswe ukubaxPONngoku sesona sisombululo siphambili seGigabit/10 Gigabit ukufikelela ekhaya.
I-PON ye-10 yeGigabit yokufikelela ekhaya
Idatha ibonisa ukuba ekupheleni kuka-Epreli ka-2023, inani lilonke labasebenzisi bokufikelela kwi-intanethi esisigxina kwilizwe lam lizigidi ezingama-608, apho inani lilonke lokufikelela kwi-fiber optical abasebenzisi be-FTTH lifikelele kwi-580 yezigidi, libalelwa kwi-95% yetotali. inani labasebenzisi bebroadband abasisigxina; abasebenzisi begigabit bafikelele kwi-115 yezigidi. Ukongezelela, inani le-fiber access (FTTH / O) izibuko lifikelele kwi-1.052 yezigidigidi, i-akhawunti ye-96% ye-intanethi ye-broadband access port, kunye nenani le-10G i-PON port kunye ne-Gigabit network service capabilities ifikelele kwi-18.8 yezigidi. Kuyabonakala ukuba iziseko zenethiwekhi yelizwe lam zihlala ziphuhliswa, kwaye amakhaya amaninzi kunye namashishini afikelele kwisantya senethiwekhi yegigabit.
Nangona kunjalo, njengoko imigangatho yokuphila iqhubeka nokuphucula kwaye ibe nengqondo, iofisi ye-intanethi / intlanganiso / intsebenziswano yomsebenzi / ukuthengwa kwe-intanethi / ubomi / isifundo kuya kuba neemfuneko eziphezulu kumgangatho wenkonzo yenethiwekhi, kwaye abasebenzisi baya kuqhubeka benemfuno eziphezulu zesantya senethiwekhi. Phakamisa ulindelo oluthile. “Ke ngoko kuseyimfuneko ukuqhubeka ukonyusa izinga lofikelelo, kwaye uqonde i-10G,” watsho uMao Qian.
Ukuphumelela1G/ 10 Ukufikelela ekhaya kweGigabit kwisikali esikhulu, kungekhona kuphelaI-EPON kunye ne-GPONabanabuchule, kodwa kwakhona ukugubungela i-10GEPON kunye ne-XGPON ayinkulu ngokwaneleyo, kwaye ukusebenza kakuhle kuphantsi. Ngoko ke, i-PON ephezulu kakhulu iyadingeka, kwaye i-evolution ukuya kwi-50G PON okanye nokuba yi-100G ye-PON iyimfuneko Indlela engenakuphepheka. Ngokutsho kuka-Mao Qian, ukugweba ukusuka kwindlela yophuhliso lwangoku, i-shishini lithambekele ngakumbi kwi-single-wavelength 50G PON, exhasa iteknoloji eyahlukeneyo ye-10G ye-broadband. Ababoneleli abaphambili bonxibelelwano lwasekhaya sele benamandla e-50G PON, kwaye abanye ababoneleli baye baqaphela i-100G PON, ukubonelela ngeemeko ezisisiseko kwi-10G yokufikelela ekhaya.
Ethetha ngetekhnoloji yeGigabit kunye ne-10 ye-Gigabit yokufikelela ekhaya ngokweenkcukacha, uMao Qian uthe kwangethuba kwi-2017 Shenzhen Optical Expo, wayecebise ukudityaniswa kwe-network optical network kunye nenethiwekhi ye-optical esebenzayo. Emva kokuba izinga lokufikelela elifunwa ngumsebenzisi omnye liyenyuka kwinqanaba elithile (umzekelo, ngaphezu kwe-10G), inethiwekhi ye-optical esebenzayo ingaba lula, kulula ukuyiphucula kunye neendleko eziphantsi kune-passive optical network ukunika amazinga aphezulu; kwi-Shenzhen Optical Expo ngo-2021 Kwi-OptiNet, wade wacebisa ukuba abasebenzisi abane-bandwidth ye-10 Gigabit nangaphezulu kufuneka baqwalasele iskimu se-bandwidth ekhethekileyo; kwi-OptiNet ngo-2022, ucebise ukuba i-bandwidth ekhethekileyo inokuphunyezwa ngeendlela ezahlukeneyo: i-bandwidth ekhethekileyo yeXG/XGS-PONabasebenzisi, i-P2P i-fiber ebonakalayo ikhethekileyo, i-NG-PON2 yavelength ekhethekileyo, njl.
“Ngoku kubonakala ngathi inkqubo yobude obubodwa ineendleko ezingaphezulu kunye neenzuzo zobugcisa, kwaye iya kuba yindlela yophuhliso. Ewe kunjalo, izikimu ezikhethekileyo ze-bandwidth zinezibonelelo zazo kunye nokungalunganga, kwaye unokukhetha ngokweemeko zasekhaya. ” UMao Qian uthe.
