ONU inoshanda sei

ONU yakakamurwa kuita inoshanda optical network unit uye passive optical network unit.
Kazhinji, michina ine optical receivers, uplink optical transmitters, uye akawanda mabhiriji amplifiers ekutarisisa network inonzi optical node.

ONU basa
1. Sarudza kugamuchira nhepfenyuro data inotumirwa neOLT;
2. Pindura kumirairo yekudzora uye simba rekutonga rakapihwa neOLT;uye gadzirisa zvinoenderana;
3. Bafa data reEthernet remushandisi uye woitumira kwakananga kumusoro muhwindo rekutumira rakagoverwa neOLT.
Inonyatsoenderana neIEEE 802.3/802.3ah
Gamuchira kunzwa kunosvika -25.5dBm
Tumira simba kusvika -1 kusvika +4dBm
Imwe optical fiber inopa masevhisi akadai sedata, IPTV, uye izwi, uye inonyatso ziva "katatu-kutamba" maapplication.
· Yepamusoro mwero PON: kumusoro uye downlink symmetrical 1Gb/s data, VoIP izwi uye IP vhidhiyo masevhisi.the
ONU "plug uye tamba" zvichibva pakuwana otomatiki uye kugadzirisa
Yepamberi Hunhu hweSevhisi (QoS) maficha anoenderana neSevhisi Level Agreement (SLA) kubhadharisa
Remote manejimendi masimba anotsigirwa neakapfuma uye ane simba OAM mabasa
High senitivity mwenje inogamuchira uye yakaderera yekuisa mwenje mashandisiro emagetsi

Active Optical network unit
Iyo inoshanda optical network unit inonyanya kushandiswa mukubatanidzwa kwematatu network.Iyo inobatanidza CATV yakazara-bhendi RF kubuda;yepamusoro-mhando yeVOIP audio;matatu-layer routing modhi, isina waya uye mamwe mabasa, uye nyore kuona iyo terminal michina yekuwana iyo katatu network yekubatanidza.
Passive Optical Network Unit
Iyo passive optical network unit ndeye mushandisi-padivi mudziyo weGPON (Gigabit Passive Optical Network) system, uye inoshandiswa kumisa masevhisi anofambiswa kubva kuOLT (Optical Line Terminal) kuburikidza nePON (Passive Optical Network).Kubatana neOLT, ONU inogona kupa akasiyana siyana mabhendi masevhisi kune akabatana vashandisi.Zvakadai seInternet surfing, VoIP, HDTV, Vhidhiyo Musangano uye mamwe masevhisi.Semushandisi-parutivi mudziyo weFTTx application, ONU ndeye yakakwirira-bandwidth uye inodhura-inoshanda terminal mudziyo unodiwa pakuchinja kubva ku "copper cable era" kuenda ku "optical fiber era".Semhinduro yekupedzisira yekuwanikwa kwewaya kwevashandisi, GPON ONU ichaita basa rakasimba mukuvakwa kwenetiweki kweNGN (Next Generation Network) mune ramangwana.
HG911 ONU inodhura-inoshanda mushandisi terminal michina yexPON system.Yakagadzirirwa vashandisi vekumba uye vashandisi veSOHO, ichipa gigabit-speed Broadband yekubatanidza kumagedhi evashandisi uye / kana maPC.ONU inopa imwe 1000Base-T Ethernet port yedata uye IPTV vhidhiyo masevhisi.Inogona kugadzirwa kure uye kutungamirirwa neHUANET series optical line terminal (OLT).
Applications
Iyo ONU kumusoro kwerwizi inobatanidza kuhofisi yepakati (CO) kuburikidza nechiteshi chexPON, uye maitiro ezasi anopa Gigabit Ethernet chiteshi chevashandisi vega kana vashandisi veSOHO.Semhinduro yeramangwana yeFTTx, ONU 1001i inopa izwi rine simba, data-yekukurumidza uye masevhisi evhidhiyo kuburikidza nefiber imwe GEPON.
