Igikoresho cya ONU ni iki?

ONU (Optical Network Unit) optique y'urusobekerane, ONU igabanijwemo urwego rukora rwa optique hamwe na pasiporo optique.Mubisanzwe, ibikoresho bifite ibikoresho byo gukurikirana imiyoboro harimo optique yakira, imiyoboro yo hejuru ya optique, hamwe ninshi byongera ibiraro byitwa optique node.PON ikoresha fibre optique imwe kugirango ihuze na OLT, hanyuma OLT ihuza ONU.ONU itanga serivisi nkamakuru, IPTV (ni ukuvuga tereviziyo ya interineti ihuza interineti), nijwi (ukoresheje IAD, ni ukuvuga Integrated Access Device), ukamenya rwose "gukinisha gatatu".

Ibiranga

Hitamo kwakira amakuru yatangajwe yoherejwe na OLT;

Subiza amategeko aringaniza nimbaraga zo kugenzura zitangwa na OLT;no kugira ibyo uhindura;

Koresha amakuru yumukoresha wa Ethernet hanyuma wohereze kumurongo woherejwe mumadirishya yoherejwe na OLT;

Kurikiza byuzuye IEEE 802.3 / 802.3ah;

· Kwakira sensibilité ni hejuru -25.5dBm;

· Kohereza ingufu kugeza kuri -1 kugeza kuri + 4dBm;

PON ikoresha fibre optique imwe kugirango ihuze na OLT, hanyuma OLT ihuza ONU.ONU itanga serivisi nkamakuru, IPTV (ni ukuvuga tereviziyo ya interineti ihuza interineti), nijwi (ukoresheje IAD, ni ukuvuga Integrated Access Device), ukamenya porogaramu “eshatu-ikina”;

· Igipimo cyo hejuru cyane PON: ihuza 10Gb / s yo hejuru no kumanuka, amakuru ya VoIP na serivisi za videwo IP;

· ONU “gucomeka no gukina” ishingiye kubuvumbuzi bwikora no kuboneza;

· Iterambere ryiza rya serivisi (QoS) rishingiye kumasezerano yo kurwego rwa serivisi (SLA);

· Ubushobozi bwo kuyobora kure bushigikiwe nibikorwa bikize kandi bikomeye OAM;

· Umucyo mwinshi wakira no gukoresha urumuri ruke rwinjiza;

· Gushyigikira ibikorwa bipfa gupfa;

Ibyiciro

Umucyo ukora

Igice gikora cya optique gikoreshwa cyane cyane iyo imiyoboro itatu ihuriweho, kandi igahuza CATV yuzuye-ibisohoka RF;amajwi meza ya VOIP;uburyo butatu bwo kugenderaho, uburyo butagendanwa nibindi bikorwa, bishobora gutahura byoroshye gukina-gukina-gukina ibikoresho bitatu byinjira.

Itara ryoroshye

Passive ONU (Optical Network Unit) nigikoresho cyumukoresha kuruhande rwa sisitemu ya GEPON (Gigabit Passive Optical Network) sisitemu, ikoreshwa muguhagarika serivisi ziva muri OLT (Optical Line Terminal) binyuze muri EPON (Passive Optical Network).Gufatanya na OLT, ONU irashobora gutanga serivise zitandukanye mugari kubakoresha.Nkurubuga rwa interineti, VoIP, HDTV, VideoInama nizindi serivisi.ONU, nkigikoresho cyumukoresha kuruhande rwa porogaramu ya FTTx, nigikoresho kinini kandi cyigiciro cyingirakamaro gikenewe muguhinduka kuva "mugihe cyumuringa wumuringa" ujya "optique fibre".Nkigisubizo cyibanze kubakoresha gukoresha insinga, GEPON ONU izagira uruhare runini mukubaka imiyoboro rusange ya NGN (Next Generation Network) mugihe kizaza.

UTStarcom ONU 1001i nigikoresho gikoresha ibikoresho bya terefone ikoreshwa muri sisitemu ya GEPON.Yashizweho kubakoresha murugo hamwe nabakoresha SOHO, kandi itanga umurongo mugari wa gigabit kubakoresha amarembo na / cyangwa PC.ONU 1001i itanga icyambu kimwe 1000Base-TEthernet port ya data na serivisi za videwo ya IPTV.ONU1001i irashobora gushyirwaho kure kandi igacungwa na UTStarcom BBS ikurikirana ya optique y'umurongo (OLT).

Porogaramu

Hejuru ya ONU 1001i ihujwe n'ibiro bikuru (CO) binyuze ku cyambu cya GEPON, naho epfo ni iy'abakoresha ku giti cyabo cyangwa abakoresha SOHO gutanga icyambu cya 1 Gigabit Ethernet.Nkigisubizo kizaza cya FTTx, ONU 1001i itanga ijwi rikomeye, amakuru yihuta na serivisi za videwo binyuze muri fibre imwe GEPON.
