Zomwe zimatchedwa PON network zimakhala ndi magawo atatu:OLT, ODN ndiONU.AnOLTchipangizo chili pakatikati 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 ndiye maziko a netiweki ya PON potengera malo ake a netiweki kapena ntchito ya netiweki. Ndi ntchito zochulukirachulukira monga kupezeka kwa intaneti, kanema wa 4K IPTV, ntchito zapanyumba zanzeru, mizere yodzipereka yamabizinesi ang'onoang'ono ndi apakatikati, mawu a IMS, ndi mafoni am'mbuyo amayendetsedwa pa netiweki ya PON, kufunikira kwa bandwidth ndi kuchuluka kwa kuwongolera kasamalidwe akupitiriza kuwonjezeka .Kukula kwa teknoloji ya PON ndi kutumizidwa ndi kusinthika kwaOLTzida zimagwira ntchito yofunika kwambiri pakupanga maukonde ofikira mabroadband.
Kusanthula kwa PON network status
(1)OLTkutumiza zida
TheOLTzida za ogwira ntchito zapakhomo zidagwiritsidwa ntchito mu 2006, ndipo zidagwiritsidwa ntchito makamaka pofikira PON + DSL poyambira. Kuyambira 2009, FTTH yakhala ikugwiritsidwa ntchito pamlingo waukulu kwa zaka zoposa 10. Malinga ndi bandiwifi kagawo, mphamvu yosinthira makina onse, ndi kuthandizira kwa khadi la bolodi la PON, pali mibadwo 2 ~ 3 yazinthu zomwe zikuyenda mu network yapano. ntchito zapaintaneti zamakono zimafika pa 40G/kagawo, ndipo zonse zimathandizira 10G EPON ndi XG-PON1.
(2) Kutumiza kwaukadaulo wa PON
Pogwiritsa ntchito pang'onopang'ono malonda a teknoloji ya 10G PON, makadi a PON opangidwa ndiOLTzipangizo mu maukonde panopa anawagawa mitundu inayi: EPON, GPON, 10G EPON ndi XG-PON, mwa amene EPON ndi GPON ndi zazikulu.
Polimbikitsa kusintha kwa miyezo ya EPON ndi China Telecom ndi China Unicom, EPON yogwiritsira ntchito pakhomo imagulitsidwa zaka ziwiri mpaka 3 kale kuposa GPON. Isanafike 2013, ntchito yomangayi inkalamulidwa ndi EPON, ndiyeno, chifukwa cha ubwino wa GPON mu bandwidth, pang'onopang'ono idakhala ndi udindo waukulu.OLTkumanga. Kutengera momwe ma network akugwiritsidwira ntchito panopa, aOLTzida za China Unicom ndi China Mobile makamaka GPON, pamene China Telecom makamaka EPON.
Kumanga kwa 10G PON kunayamba kuzungulira 2015. Monga mtengo wa 10G optical module nthawi zonse umakhala wokwera kwambiri, mtengo wa 10G PON ONT uli pafupi ndi 5 nthawi za EPON / GPON zomwe zilipo. M'malo apano omwe ogwira ntchito nthawi zambiri amapereka malo kwa makasitomala, ndipo kufunikira kwa bizinesi kumakhala pansi pa 100 Mbit / s, ogwira ntchito onse akuluakulu amasamala za kutumizidwa ndi kugwiritsa ntchito 10G PON. Pakalipano, njira yomanga ya 10G PON imagwiritsidwa ntchito makamaka mu 10 GPON + LAN ndi FTTH deployment.10 GPON + LAN makamaka kusintha ma cell omwe alipo LAN, network ndi PON + LAN network. Kumbali imodzi, imathetsa vuto la bandwidth yosakwanira chifukwa cha kuchuluka kwa ogwiritsa ntchito; Kumbali inayi, popeza ogwiritsa ntchito ambiri amagawana mtengo wa optical module mu MDU, mtengo wonse umakwera pang'ono poyerekeza ndi PON + LAN, kotero ili ndi ntchito yaikulu, ndipo 10G PON ndi XG-PON imatengedwa. Kumanga kwa 10G PON FTTH makamaka ndi ntchito yoyesa yochitidwa ndi ogwira ntchito osiyanasiyana. Cholinga chachikulu ndikulengeza ndikutsimikizira zopangidwa za 10G PON FTTH.
Zomwe zili pamwambazi ndizofotokozera za dongosolo lonse la PON network. Zogulitsa pa netiweki za Shenzhen HDV Photoelectronic Technology Co., Ltd. zonse ndi zida zopangidwa mozungulira netiweki ya PON, kuphatikizaONUmndandanda /OLTmndandanda / kuwala module mndandanda / transceiver mndandanda ndi zina zotero.
