Ndi kutumizidwa ndi kukhazikitsidwa kwa kusintha kwa kuwala kwa netiweki ya Broadband, maukonde amakongoletsedwa bwino, kulephera kumachepa, ndipo chidwi cha wogwiritsa ntchito chikuwonjezeka. Pakadali pano, kupangidwa kwa netiweki yofikira kwa Broadband kumayendetsedwa ndi FTTH ndikuphatikizidwa ndi PON + LAN. Ngati maukonde amtundu wamtundu wamtsogolo atengera ukadaulo wa PON pamanetiweki, sangangopereka chidziwitso chapamwamba cha ogwiritsa ntchito, komanso kuchepetsa ndalama zoyendetsera bizinesi ndikuwongolera phindu lazachuma. Chotsatira, nkhaniyi ipereka malingaliro pazachitukuko chaukadaulo ndi kutumiza kwa 10G PON potengera zofunikira zamabizinesi.
Kodi network ya PON ndi chiyani
PON network imakhala ndiOLT, ODN ndiONU. AnOLTchipangizo chiri pachimake pa network topology. Imapeza mautumiki angapo opita kumtunda ndi ntchito za ogwiritsa ntchito angapo kutsika kudzera mu ODN. Ndi gawo lofunikira pakuphatikiza ndi kugawa ntchito.OLTnthawi yomweyo amazindikira ntchito zambiri kasamalidwe maukonde monga kulamulira, kasamalidwe, kuyambira ndi zina zotero kwa kasitomala chipangizoONU. OLTzida zili pamtima pa netiweki ya PON, potengera malo omwe ali ndi netiweki komanso luso lawo la netiweki. Pomwe ntchito zochulukirachulukira monga kupezeka kwa intaneti, kanema wa 4K IPTV, ntchito zapanyumba zanzeru, mizere yabizinesi yaying'ono ndi apakatikati, mawu a IMS, ndi mafoni am'mbuyo amayendetsedwa pa netiweki ya PON, kufunikira kwa bandwidth ndi kuchuluka kwa kuwongolera kasamalidwe kupitiriza kukula. Kukula kwaukadaulo wa PON komanso kusinthika kwa kutumizaOLTzida zimagwira ntchito yofunika kwambiri pakupanga ma network a Broadband access..
PON network kusanthula
(1)OLTkutumiza zida
TheOLTzida za ogwira ntchito zapakhomo zidayamba kugwiritsidwa ntchito mu 2006, ndipo zidagwiritsidwa ntchito kwambiri pofikira PON + DSL poyambira. Patha zaka zoposa 10 kuyambira FTTH anayamba kutumizidwa pamlingo waukulu mu 2009. Malinga ndi kagawo bandiwifi, wonse kusintha mphamvu, ndi PON bolodi thandizo, pali 2-3 mibadwo ya mankhwala kuthamanga pa maukonde moyo. Pa netiweki yamoyo, mphamvu yosinthira kagawo kamodzi ka chipangizo chachikulu chokankhira chimafika 40 Gbit/s ndikuthandizira 10 Gbit/s EPON ndi XG-PON1.
(2) Kutumiza kwaukadaulo wa PON
Ndi ukadaulo wapang'onopang'ono wa 10G PON, ma board a PON adasinthidwaOLTZida zomwe zili pa intaneti zimagawidwa kukhala EPON, GPON, 10G EPON ndi XG-PON, zomwe EPON ndi GPON ndizo zikuluzikulu. Pansi pa Kukwezeleza China Telecom ndi China Unicom kusintha muyezo EPON, ntchito malonda EPON ndi ogwira ntchito zapakhomo anali pafupi zaka 2-3 kale kuposa GPON.Pamaso pa 2013, yomanga ankalamulidwa ndi EPON, ndipo kenako, chifukwa cha ubwino. ya GPON mu bandwidth, idalamulira pang'onopang'ono ntchito yomangaOLT. Kutengera momwe ma network akutumizidwa, China Unicom ndi China Mobile'sOLTzida makamaka GPON, ndipo China Telecom makamaka EPON.
Kumanga kwa 10G PON kunayamba kuzungulira 2015. Chifukwa cha mtengo wapamwamba wa 10G optical modules, mtengo wa 10G PON ONT uli pafupi kasanu kuposa zomwe zilipo kale za EPON / GPON. M'malo apano pomwe ma terminal nthawi zambiri amaperekedwa ndi wogwiritsa ntchito kwa kasitomala, ndipo kufunikira kwautumiki kumakhala pansi pa 100Mbit / s, ogwira ntchito akuluakulu amasamala za kutumizidwa kwa mapulogalamu a 10G PON. Pakalipano, njira yomanga 10G PON imagwiritsidwa ntchito makamaka mu 10G PON + LAN ndi FTTH. 10G PON+ LAN makamaka kusintha kwa ma cell a LAN network ndi PON+ LAN network. Kumbali imodzi, thetsani kuchepa kwa bandwidth chifukwa cha kuchuluka kwa ogwiritsa ntchito; Kumbali ina, chifukwa ogwiritsa ntchito angapo amagawana mtengo wa ma module opangira mu MDU, mtengo wake sukwera kwambiri poyerekeza ndi netiweki ya PON + LAN, chifukwa chake wagwiritsidwa ntchito pamlingo, ndipo mwaukadaulo 10G PON ndi XG-PON amagwiritsidwa ntchito. . Kupanga kwa 10G PON FTTH makamaka ndi woyendetsa nyumba wa gigabit wochitidwa ndi ogwira ntchito osiyanasiyana, ndipo cholinga chachikulu ndikulengeza ndi kutsimikizira malonda a 10G PON FTTH.
Pafupifupi 10G (gigabit khumi) ukadaulo wa Efaneti ndi kugwiritsa ntchito ndizozidziwitso pamwambapa, zaOLTzida zomwe tazitchula pamwambazi ku Shenzhen HDV Phoelectron Technology Ltd. zili m'gulu lodziwika bwino lazinthu zolumikizirana, monga:OLT kusintha, GPONOLT, EPONOLT, Kuwala MphakaOLT, ndi zina, pamwambaOLTzida zingagwiritsidwe ntchito m'malo osiyanasiyana, pazosowa zosiyanasiyana za ogwiritsa ntchito kuti apereke zosankha zambiri, kulandiridwa kuti mumvetse, tidzapereka ntchito yabwino kwambiri.
