Nigute ONU ikora

ONU igabanijwemo ibikorwa bya optique y'urusobekerane hamwe na optique ya optique.
Mubisanzwe, ibikoresho bifite ibikoresho byakira optique, uplink optique yohereza, hamwe na amplifier nyinshi yikiraro kugirango ikurikirane imiyoboro yitwa optique node.

Imikorere ya ONU
1. Hitamo kwakira amakuru yatangajwe yoherejwe na OLT;
2. Subiza amategeko aringaniza kandi agenzura ingufu zitangwa na OLT;no kugira ibyo uhindura;
3. Hindura amakuru yumukoresha wa Ethernet hanyuma wohereze mucyerekezo cyo hejuru mumadirishya yoherejwe na OLT.
Byuzuye byuzuye na IEEE 802.3 / 802.3ah
Akira ibyiyumvo bigera kuri -25.5dBm
Kohereza imbaraga kugeza kuri -1 kugeza kuri + 4dBm
Fibre optique imwe itanga serivisi nkamakuru, IPTV, nijwi, kandi ikamenya mubyukuri "gukinisha gatatu".
· Igipimo cyo hejuru PON: kuzamura no kumanura amakuru ya 1Gb / s, amajwi ya VoIP na serivisi za videwo IP.i
ONU "gucomeka no gukina" ishingiye kubuvumbuzi bwikora no kuboneza
Iterambere ryiza rya serivisi (QoS) rishingiye ku kwishyuza urwego rwa serivisi (SLA)
Ubushobozi bwo kuyobora kure bushigikiwe nibikorwa bikize kandi bikomeye OAM
Umucyo mwinshi wakira kandi winjiza urumuri ruke
Shigikira Gupfa Imikorere
Igice gikora neza
Igikoresho gikora optique ikoreshwa cyane muguhuza imiyoboro itatu.Ihuza CATV yuzuye-ibisohoka RF ibisohoka;amajwi meza ya VOIP;uburyo butatu bwo kugenderaho, uburyo butagendanwa nibindi bikorwa, kandi byoroshye kubona ibikoresho byanyuma byinjira muburyo butatu bwo guhuza.
Igice cya Optical Network Unit
Igice cya pasiporo optique nigikoresho cyumukoresha-uruhande rwa sisitemu ya GPON (Gigabit Passive Optical Network), kandi ikoreshwa muguhagarika serivisi ziva muri OLT (Optical Line Terminal) zinyuze kuri PON (Umuyoboro wa Passive Optical Network).Gufatanya na OLT, ONU irashobora gutanga serivise zitandukanye mugari kubakoresha.Nkurubuga rwa interineti, VoIP, HDTV, Ihuriro rya Video nizindi serivisi.Nkumukoresha-uruhande rwibikoresho bya FTTx, ONU nigikoresho kinini kandi cyigiciro cyingirakamaro gikenewe kugirango uhindurwe kuva "mugihe cyumuringa wumuringa" ujya "optique ya fibre optique".Nkigisubizo cyanyuma kubakoresha gukoresha insinga, GPON ONU izagira uruhare rukomeye mukubaka imiyoboro rusange ya NGN (Next Generation Network) mugihe kizaza.
HG911 ONU nigikoresho gikoresha ibikoresho bya terefone ya sisitemu ya xPON.Yashizweho kubakoresha urugo hamwe nabakoresha SOHO, itanga gigabit-yihuta ya Broadband ihuza abakoresha amarembo na / cyangwa PC.ONU itanga icyambu kimwe 1000Base-T Ethernet ya data na serivisi za videwo ya IPTV.Irashobora gushyirwaho kure kandi igacungwa na serivise ya HUANET optique y'umurongo (OLT).
Porogaramu
ONU yo hejuru ihuza ibiro bikuru (CO) ikoresheje icyambu cya xPON, kandi imyitwarire yo hasi itanga icyambu cya Gigabit Ethernet kubakoresha kugiti cyabo cyangwa abakoresha SOHO.Nkigisubizo kizaza kuri FTTx, ONU 1001i itanga ijwi rikomeye, amakuru yihuta na serivisi za videwo binyuze muri fibre imwe GEPON.
