Iindaba zeHlabathi zoNxibelelwano (CWW) KwiSemina yeNethiwekhi ye-Optical yaseTshayina ka-2023 ebibanjwe nge-14-15 kaJuni, uMao Qian, umcebisi weKomiti yeSayensi yoNxibelelwano kunye neTekhnoloji yoMphathiswa wezoShishino kunye neTekhnoloji yoLwazi, umlawuli weKomiti yoNxibelelwano lwe-Optical yaseAsia-Pacific, kunye nosihlalo-kunye weSemina yeNethiwekhi ye-Optical yaseTshayina. Kucacisiwe ukubaxPONokwangoku sisisombululo esiphambili sokufikelela ekhaya kwiGigabit/10 Gigabit.
Ukufikelela ekhaya nge-PON 10 Gigabit
Idatha ibonisa ukuba ekupheleni kuka-Epreli 2023, inani lilonke labasebenzisi bokufikelela kwi-intanethi esisigxina kwilizwe lam lizigidi ezingama-608, apho inani lilonke labasebenzisi be-FTTH abafikelela kwi-optical fiber lifikelele kwizigidi ezingama-580, elibalelwa kwi-95% yenani lilonke labasebenzisi be-intanethi esisigxina; abasebenzisi be-gigabit bafikelele kwizigidi ezili-115. Ukongeza, inani lee-fiber access (FTTH/O) ports lifikelele kwi-1.052 yeebhiliyoni, elibalelwa kwi-96% yee-intanethi, kwaye inani lee-10G PON ports ezineenkonzo zenethiwekhi ye-Gigabit lifikelele kwizigidi ezili-18.8. Kuyabonakala ukuba iziseko zenethiwekhi zelizwe lam zihlala ziphuhla, kwaye amakhaya amaninzi kunye namashishini afikelele kwisantya senethiwekhi ye-gigabit.
Nangona kunjalo, njengoko imigangatho yokuphila iqhubeka iphucuka kwaye iba krelekrele ngakumbi, iofisi/intlanganiso/unxibelelwano lomsebenzi kwi-intanethi/ukuthenga kwi-intanethi/ubomi/ukufunda kuya kuba neemfuno eziphezulu zomgangatho wenkonzo yenethiwekhi, kwaye abasebenzisi baya kuqhubeka beneemfuno eziphezulu zesantya senethiwekhi. Phakamisa ulindelo oluthile. "Ngoko ke kusafuneka ukunyusa izinga lokufikelela rhoqo, kwaye ufezekise i-10G,” watsho uMao Qian.
Ukuphumelela1G/10 Ukufikelela ekhaya ngeGigabit ngomlinganiselo omkhulu, kungekuphela njeI-EPON kunye ne-GPONAbakwazi, kodwa ukugubungela i-10GEPON kunye ne-XGPON akwanele, kwaye ukusebenza kakuhle kuphantsi. Ke ngoko, kufuneka i-PON ekhawulezayo, kwaye ukuguqukela kwi-50G PON okanye i-100G PON kuyimfuneko ebalulekileyo. Ngokutsho kukaMao Qian, xa sijonga indlela yophuhliso lwangoku, eli shishini lithambekele ngakumbi kwi-50G PON enye, exhasa ubuchwepheshe obahlukeneyo be-10G broadband. Ababoneleli abaphambili bonxibelelwano lwasekhaya sele benamandla e-50G PON, kwaye abanye ababoneleli nabo bafumene i-100G PON, bebonelela ngeemeko ezisisiseko zokufikelela ekhaya kwi-10G.
Ethetha ngetekhnoloji yeGigabit kunye ne-10 Gigabit yokufikelela ekhaya ngokweenkcukacha, uMao Qian uthe kwasekuqaleni kweShenzhen Optical Expo ka-2017, wayecebise ukudityaniswa kwenethiwekhi ye-optical engasebenziyo kunye nenethiwekhi ye-optical esebenzayo. Emva kokuba izinga lokufikelela elifunekayo kumsebenzisi omnye linyuke ukuya kwinqanaba elithile (umzekelo, elingaphezulu kwe-10G), inethiwekhi ye-optical esebenzayo inokuba lula ngakumbi, kube lula ukuyiphucula kwaye ixabise kancinci kunenethiwekhi ye-optical engasebenziyo ukubonelela ngamanani aphezulu; kwiShenzhen Optical Expo ngo-2021 Kwi-OptiNet, wade wacebisa ukuba abasebenzisi abane-bandwidth ye-10 Gigabit nangaphezulu bafanele baqwalasele iskimu se-bandwidth ekhethekileyo; kwi-OptiNet ngo-2022, wacebisa ukuba i-bandwidth ekhethekileyo inokusetyenziswa ngeendlela ezahlukeneyo: i-bandwidth ekhethekileyo yeI-XG/XGS-PONabasebenzisi, i-P2P optical fiber ekhethekileyo, i-NG-PON2 wavelength ekhethekileyo, njl.
“Ngoku kubonakala ngathi iskimu se-exclusive wavelength sineendleko ezingaphezulu kunye neenzuzo zobugcisa, kwaye siya kuba ngumkhwa wophuhliso. Kakade ke, iiskimu ezahlukeneyo ze-bandwidth exclusive zinezibonelelo kunye neengxaki zazo, kwaye ungakhetha ngokweemeko zasekuhlaleni.” utshilo uMao Qian.
