ONU(umuyoboro wa optique) optique node.ONUigabanijwemo ibikorwa bya optique yibikoresho hamwe nububiko bwibitabo passique optique yumurongo.Muri rusange, ibikoresho bifite ibikoresho byo kugenzura imiyoboro harimo optique yakira, uplink optique transmitter hamwe na amplifier nyinshi yikiraro yitwa optique node.

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

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 naOLT, hanyuma hanyumaOLTIhuza KuriONU. ONUitanga 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: simmetrike 1Gb / s hejuru no mumakuru yo hasi, 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
