Nkhani Zapadziko Lonse Zolumikizirana (CWW) Pa Msonkhano wa China Optical Network wa 2023 womwe unachitika pa 14-15 June, Mao Qian, mlangizi wa Komiti Yolankhulana ya Sayansi ndi Ukadaulo wa Unduna wa Zamakampani ndi Ukadaulo wa Chidziwitso, mkulu wa Komiti Yolankhulana ya Asia-Pacific Optical, komanso wapampando wa Msonkhano wa China Optical Network.xPONPakadali pano ndiye njira yayikulu yothetsera vuto la kugwiritsa ntchito intaneti ya Gigabit/10 Gigabit kunyumba.
PON 10 Gigabit yolowera kunyumba
Deta ikuwonetsa kuti pofika kumapeto kwa Epulo 2023, chiwerengero chonse cha ogwiritsa ntchito intaneti yokhazikika m'dziko langa ndi 608 miliyoni, pomwe chiwerengero chonse cha ogwiritsa ntchito FTTH chofikira ulusi wa optical fiber chafika 580 miliyoni, chomwe chimapanga 95% ya chiwerengero chonse cha ogwiritsa ntchito intaneti yokhazikika; ogwiritsa ntchito gigabit afika 115 miliyoni. Kuphatikiza apo, chiwerengero cha madoko ofikira ulusi (FTTH/O) chafika 1.052 biliyoni, chomwe chimapanga 96% ya madoko ofikira intaneti yokhazikika, ndipo chiwerengero cha madoko a 10G PON okhala ndi mphamvu zogwirira ntchito pa intaneti ya Gigabit chafika 18.8 miliyoni. Zikuoneka kuti zomangamanga za netiweki ya dziko langa zikukula nthawi zonse, ndipo nyumba ndi mabizinesi ambiri afika pa liwiro la netiweki ya gigabit.
Komabe, pamene miyezo ya moyo ikupitirirabe kusintha ndikukhala anzeru kwambiri, maofesi/misonkhano/ntchito pa intaneti/kugula pa intaneti/moyo/kuphunzira kudzakhala ndi zofunikira kwambiri pa ubwino wa utumiki wa netiweki, ndipo ogwiritsa ntchito apitiliza kukhala ndi zofunikira zapamwamba pa liwiro la netiweki. Wonjezerani ziyembekezo zina. "Chifukwa chake ndikofunikirabe kuonjezera nthawi zonse kuchuluka kwa anthu olowa, ndikukwaniritsa 10G"," Mao Qian adatero.
Kukwaniritsa1G/10 Kufikira kunyumba kwa Gigabit pamlingo waukulu, osati kokhaEPON ndi GPONSizili bwino, komanso kufalikira kwa 10GEPON ndi XGPON sikokwanira, ndipo magwiridwe antchito ake ndi ochepa. Chifukwa chake, pakufunika PON yothamanga kwambiri, ndipo kusintha kwa 50G PON kapena 100G PON ndikofunikira kwambiri. Malinga ndi Mao Qian, potengera zomwe zikuchitika pakadali pano, makampaniwa amakonda kwambiri 50G PON imodzi, yomwe imathandizira ukadaulo wosiyanasiyana wa 10G broadband. Opereka mauthenga apakhomo ambiri ali kale ndi mphamvu ya 50G PON, ndipo ogulitsa ena apezanso 100G PON, zomwe zimapangitsa kuti 10G ifike kunyumba.
Polankhula za ukadaulo wa Gigabit ndi 10 Gigabit home access mwatsatanetsatane, Mao Qian adati kuyambira pa 2017 Shenzhen Optical Expo, adapereka lingaliro lophatikiza passive optical network ndi active optical network. Pambuyo poti access rate yomwe wogwiritsa ntchito m'modzi amafunikira ikwere kufika pamlingo winawake (mwachitsanzo, yoposa 10G), active optical network ikhoza kukhala yosavuta, yosavuta kukweza komanso yotsika mtengo kuposa passive optical network kuti ipereke mitengo yokwera; pa Shenzhen Optical Expo mu 2021 Pa OptiNet, adapereka lingaliro loti ogwiritsa ntchito omwe ali ndi bandwidth ya 10 Gigabit ndi kupitilira apo ayenera kuganizira za bandwidth yapadera; pa OptiNet mu 2022, adalimbikitsa kuti bandwidth yapadera igwiritsidwe ntchito m'njira zosiyanasiyana: bandwidth yapadera yaXG/XGS-PONogwiritsa ntchito, P2P optical fiber yapadera, NG-PON2 wavelength yapadera, ndi zina zotero.
"Tsopano zikuwoneka kuti dongosolo la mafunde apadera lili ndi mtengo wokwera komanso ubwino waukadaulo, ndipo lidzakhala njira yopititsira patsogolo chitukuko. Zachidziwikire, njira zosiyanasiyana za bandwidth zapadera zili ndi zabwino ndi zovuta zake, ndipo mutha kusankha malinga ndi momwe zinthu zilili m'deralo." Mao Qian adatero.
