AON ni iki?
AON numuyoboro wa optique ukora, cyane cyane ufata ingingo-ku-ngingo (PTP) yubatswe, kandi buri mukoresha arashobora kugira umurongo wa fibre optique.Umuyoboro mwiza wa optique bivuga kohereza za router, guhinduranya imashini, ibikoresho bya optique nibindi bikoresho byo guhinduranya hagati y'ibiro bikuru bikuru hamwe nogukwirakwiza abakoresha mugihe cyo kohereza ibimenyetso.Ihinduramiterere itwarwa namashanyarazi kugirango igabanye gukwirakwiza ibimenyetso nibyerekezo kubakiriya runaka.Ibikoresho bifatika birimo isoko yumucyo (laser), imashini yakira, optique ya transceiver module, amplifier optique (fibre amplifier na semiconductor optique amplifier).
PON ni iki?
PON ni Passive Optical Network, ingingo-kuri-kugwiza imiyoboro y'urusobe, kandi ni tekinoroji nyamukuru ya FTTB / FTTH.Umuyoboro wa optique uhuza ODN (umuyoboro wo gukwirakwiza optique) ukoresha gusa fibre optique hamwe nibice bya pasiporo, kandi ukeneye gusa gukoresha ibikoresho bizima kumasoko yikimenyetso no kwakira ibimenyetso birangira.Muri sisitemu isanzwe ya PON, optique itandukanya niyo ntandaro, kandi optique itandukanya ikoreshwa mugutandukanya no gukusanya ibimenyetso bya optique byanyuze kumurongo.Gutandukanya kuri PON ni byerekezo byombi.Mu cyerekezo cyo hasi, serivisi nyinshi nkamakuru ya IP, ijwi, na videwo bitangwa na OLT iherereye mubiro bikuru muburyo bwo gutangaza binyuze muri 1: N pasitike optique itandukanya muri ODN Kubice byose bya ONU kuri PON;mu cyerekezo cyo hejuru, amakuru menshi ya serivisi muri buri ONU ahujwe na fibre optique binyuze muri 1: N pasive optique ikomatanya muri ODN itabangamiye, amaherezo ikoherezwa kuri OLT ku biro bikuru kugirango yakire.
Umuyoboro mwiza wa optique urimo umurongo wa optique (OLT) washyizwe kuri sitasiyo yo hagati, hamwe nitsinda rihuza ibice bya optique (ONUs) byashyizwe kurubuga rwabakoresha.Umuyoboro wa optique wo gukwirakwiza (ODN) hagati ya OLT na ONU urimo fibre optique hamwe na pasiporo itandukanya cyangwa guhuza.PON igabanyijemo ibipimo bitatu bya tekiniki: APM ishingiye kuri ATM (ATM PON), EPON ishingiye kuri Ethernet (Ethernet PON), na GPON (Gigabit PON) ishingiye kuri Protokole rusange.
Mumuyoboro wa AON, uyikoresha afite umurongo wa fibre optique yihariye, byoroshye kubungabunga urusobe nyuma, kwagura ubushobozi, kuzamura imiyoboro, nibindi. Byongeye kandi, umuyoboro wa AON ufite intera ndende ya kilometero 100;umuyoboro wa PON mubusanzwe ugarukira kumurongo wa fibre optique kugeza kuri kilometero 20.AON iyobora cyane ibimenyetso bya optique ikoresheje ibikoresho bikora, kandi PON ikoresha ibikoresho bya pasiporo idafite amashanyarazi, bivamo amafaranga menshi yo kohereza umuyoboro wa AON kuruta PON.
