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 ukora optique bivuga koherezaRouters, guhinduranya ibikoresho, ibikoresho bya optique nibindi bikoresho byo guhinduranya hagati yibiro bikuru byo hagati 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 naOLTgiherereye mu biro bikuru muburyo bwo gutangaza binyuze muri 1: N pasitike optique itandukanya muri ODN Kuri boseONUibice kuri PON; mu cyerekezo cyo hejuru, amakuru menshi ya serivisi kuri buriONUihujwe na fibre optique imwe binyuze muri 1: N pasive optique ikomatanya muri ODN itabangamiye, hanyuma ikoherezwa kuriOLTku biro bikuru byo kwakirwa birangiye.
Umuyoboro wa optique urimo umurongo wa optique (OLT) yashyizwe kuri sitasiyo yo hagati, hamwe nitsinda rihuza imiyoboro ya optique (ONU) yashyizwe kurubuga rwabakoresha. Umuyoboro mwiza wo gukwirakwiza (ODN) hagati yaOLTnaONUikubiyemo 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.
