ONU(umuyoboro wa optique) optique node.ONU igabanyijemo ibice bya optique ya optique hamwe nububiko bwibitabo bwa pasiporo optique ya neti.Muri rusange, ibikoresho bifite ibikoresho byo kugenzura imiyoboro harimo imashini yakira optique, uplink optique ya transmitter hamwe na amplifier nyinshi yikiraro yitwa optique node.

Imikorere ya ONU

1. Hitamo kwakira amakuru yatangajwe yoherejwe naOLT;
2. Subiza amategeko aringaniza nimbaraga zo kugenzura zitangwa na OLT;no kugira ibyo uhindura;
3. Koresha amakuru yumukoresha wa Ethernet hanyuma wohereze kumurongo woherejwe mumadirishya yoherejwe na OLT.

Ibikoresho bya ONU

Kurikiza byuzuye IEEE 802.3 / 802.3ah

·Kwakira sensitivite kugeza kuri -25.5dBm

·Kohereza imbaraga kugeza kuri -1 kugeza kuri + 4dBm

·PON ikoresha fibre optique imwe kugirango ihuze na OLT, hanyumaOLTihuza na ONU.ONU itanga serivisi nkamakuru, IPTV (ni ukuvuga tereviziyo ya interineti ihuza interineti), ijwi (ukoresheje IAD, ni ukuvuga ibikoresho byinjira byinjira) hamwe nizindi serivisi, ukamenya rwose "gukinisha gatatu"

·Igipimo cyo hejuru PON: ihuza 1Gb / s hejuru yamakuru yo hepfo no hepfo, VoIP ijwi na serivisi za videwo IP

·ONU"Gucomeka no gukina" bishingiye kubuvumbuzi bwikora no kuboneza

·Iterambere ryiza rya serivisi (QoS) rishingiye kumasezerano ya serivisi (SLA) kwishyuza

·Ubushobozi bwo kuyobora kure bushigikiwe nibikorwa bikize kandi bikomeye OAM

·Umucyo mwinshi wakira kandi winjiza urumuri ruke

·Shigikira Gupfa Imikorere
