I-Communications World News (CWW) Kusemina ye-China Optical Network ka-2023 eyayibanjwe ngoJuni 14-15, uMao Qian, ongumeluleki weKomidi leSayensi Yezokuxhumana Nobuchwepheshe kuNgqongqoshe Wezimboni Nobuchwepheshe Bolwazi, umqondisi weKomidi Lezokuxhumana Lase-Asia-Pacific Optical, kanye nosihlalo obambisene naye we-China Optical Network Seminar Kuyavezwa ukuthixPONokwamanje iyisixazululo esiyinhloko sokufinyelela kwasekhaya kwe-Gigabit/10 Gigabit.
Ukufinyelela ekhaya kwe-PON 10 Gigabit
Idatha ibonisa ukuthi ekupheleni kuka-April 2023, isamba senani labasebenzisi bokufinyelela okugxilile kwe-inthanethi ezweni lami liyizigidi ezingama-608, lapho inani eliphelele labasebenzisi be-Optical fiber ukufinyelela i-FTTH selifinyelele ezigidini ezingama-580, okubalelwa ku-95% yenani eliphelele. inani labasebenzisi be-broadband abangashintshi; abasebenzisi be-gigabit sebefinyelele ezigidini eziyi-115. Ukwengeza, inani lamachweba okufinyelela i-fiber (FTTH/O) lifinyelele ku-1.052 bhiliyoni, okubalelwa ku-96% wamachweba okufinyelela ku-inthanethi ye-broadband, kanye nenani lamachweba we-10G PON anekhono lesevisi yenethiwekhi ye-Gigabit lifinyelele ezigidini eziyi-18.8. Kungabonakala ukuthi ingqalasizinda yenethiwekhi yezwe lami ikhula njalo, futhi amakhaya amaningi namabhizinisi afinyelele isivinini senethiwekhi ye-gigabit.
Kodwa-ke, njengoba izinga lokuphila liqhubeka lithuthuka futhi lihlakanipha kakhulu, ihhovisi eliku-inthanethi/umhlangano/ukusebenzelana komsebenzi/ukuthenga ku-inthanethi/ukuphila/ukufunda kuzoba nezidingo eziphakeme zekhwalithi yesevisi yenethiwekhi, futhi abasebenzisi bazoqhubeka benezidingo eziphakeme zejubane lenethiwekhi. Khulisa okulindelwe okuthile. Ngakho-ke kusadingeka ukuthi ukhuphule izinga lokufinyelela ngokuqhubekayo, futhi uqaphele u-10G,” kusho uMao Qian.
Ukufeza1G/10 Ukufinyelela kwasekhaya kwe-Gigabit ngezinga elikhulu, hhayi kuphelaI-EPON ne-GPONazikwazi, kodwa futhi ukumbozwa kwe-10GEPON ne-XGPON akukhulu ngokwanele, futhi ukusebenza kahle kuphansi. Ngakho-ke, i-PON enesivinini esiphezulu iyadingeka, futhi ukuvela ku-50G PON noma ngisho ne-100G PON kuyadingeka Ukuthambekela okungenakugwemeka. Ngokusho kuka-Mao Qian, uma sibheka kusukela ekuthuthukisweni kwamanje, imboni ithambekele kakhulu ku-single-wavelength 50G PON, esekela ubuchwepheshe obuhlukahlukene be-broadband ye-10G. Abahlinzeki abakhulu bezokuxhumana zasekhaya sebevele benamandla e-50G PON, futhi abanye abahlinzeki nabo baye baqaphela i-100G PON, ehlinzeka ngezimo eziyisisekelo zokufinyelela ekhaya kwe-10G.
Ekhuluma ngobuchwepheshe be-Gigabit kanye ne-10 Gigabit ukufinyelela ekhaya ngokuningiliziwe, uMao Qian uthe kusukela ngo-2017 Shenzhen Optical Expo, wayehlongoze inhlanganisela ye-passive optical network kanye ne-active optical network. Ngemuva kokuthi izinga lokufinyelela elidingwa umsebenzisi oyedwa likhuphukele ezingeni elithile (isibonelo, libe likhulu kune-10G), inethiwekhi ye-optical esebenzayo ingase ibe lula, kulula ukuyithuthukisa kanye nezindleko eziphansi kunenethiwekhi ye-optical ye-passive ukunikeza amanani aphezulu; e-Shenzhen Optical Expo ngo-2021 Ku-OptiNet, waze waphakamisa ukuthi abasebenzisi abane-bandwidth engu-10 Gigabit nangaphezulu kufanele bacabangele uhlelo lomkhawulokudonsa okhethekile; ku-OptiNet ngo-2022, uncome ukuthi umkhawulokudonsa okhethekile ungasetshenziswa ngezindlela ezahlukahlukene: umkhawulokudonsa okhethekile weI-XG/XGS-PONabasebenzisi, i-P2P optical fiber okukhethekile, i-NG-PON2 yavelength ekhethekile, njll.
“Manje kubonakala sengathi uhlelo olukhethekile lwe-wavelength lunezindleko ezengeziwe kanye nezinzuzo zobuchwepheshe, futhi luzoba umkhuba wentuthuko. Vele, izikimu ezikhethekile ze-bandwidth zinezinzuzo zazo kanye nebubi bazo, futhi ungakhetha ngokuya ngezimo zendawo. " Kusho uMao Qian.
