Chii chinonzi ONU mudziyo?

ONU (Optical Network Unit) optical network unit, ONU yakakamurwa kuita inoshanda optical network unit uye passive optical network unit.Kazhinji, zvishandiso zvakashongedzerwa netiweki yekutarisa zvinosanganisira optical receivers, kumusoro kwepamusoro optical transmitters, uye akawanda mabhiriji amplifiers anonzi optical nodes.Iyo PON inoshandisa imwe optical fiber kubatanidza kune OLT, uye ipapo OLT inobatana neONU.ONU inopa masevhisi akadai sedata, IPTV (kureva inopindirana network terevhizheni), uye izwi (uchishandisa IAD, kureva Integrated Access Device), kunyatsoona "kutamba-katatu" zvikumbiro.

Features

Sarudza kugamuchira nhepfenyuro data inotumirwa neOLT;

Pindura kumirairo yekudzora uye simba rekutonga rakapihwa neOLT;uye gadzirisa zvinoenderana;

Chengetedza data reEthernet remushandisi uye utumire kumusoro kumusoro muhwindo rekutumira rakagoverwa neOLT;

Teerera zvizere neIEEE 802.3/802.3ah;

·Kugamuchira kunzwisiswa kwakakwira se -25.5dBm;

·Tumira simba kusvika -1 kusvika +4dBm;

PON inoshandisa imwe optical fiber kubatanidza kune OLT, uye ipapo OLT inobatana neONU.ONU inopa masevhisi akadai sedata, IPTV (kureva interactive network terevhizheni), uye izwi (uchishandisa IAD, kureva Integrated Access Device), ichiziva "katatu-kutamba" zvikumbiro;

·Chiyero chepamusoro chePON: symmetrical 10Gb/s kukwira nekudzika data, VoIP izwi uye IP vhidhiyo masevhisi;

· ONU "plug uye tamba" zvichibva pakuwanikwa nekugadzirisa otomatiki;

·Mafambiro emhando yepamusoro yebasa (QoS) zvichienderana nekubhadharisa chibvumirano chesevhisi (SLA);

· Remote manejimendi masimba anotsigirwa neakapfuma uye ane simba OAM mabasa;

· High senitivity mwenje inogamuchira uye yakaderera yekuisa mwenje mashandisiro emagetsi;

·Kutsigira Dying Gasp basa;

Classification

Active chiedza

Iyo inoshanda optical network unit inonyanya kushandiswa kana matatu network akabatanidzwa, uye inobatanidza CATV yakazara-bhendi RF kubuda;yepamusoro-mhando yeVOIP audio;matatu-layer routing modhi, isina waya uye mamwe mabasa, ayo anogona nyore kuona matatu-kutamba yekubatanidza terminal michina yekuwana.

Passive light

Passive ONU (Optical Network Unit) ndeye mushandisi-padivi mudziyo weGEPON (Gigabit Passive Optical Network) system, iyo inoshandiswa kumisa masevhisi anotapurirwa kubva kuOLT (Optical Line Terminal) kuburikidza neEPON (Passive Optical Network).Kubatana neOLT, ONU inogona kupa akasiyana siyana mabhendi masevhisi kune akabatana vashandisi.Zvakadai seInternet surfing, VoIP, HDTV, VideoConference uye mamwe masevhisi.ONU, semushandisi-parutivi mudziyo weFTTx zvikumbiro, ndeye yakakwirira-bandwidth uye inodhura-inoshanda terminal mudziyo unodiwa pakuchinja kubva ku "copper cable era" kuenda ku "optical fiber era".Semhinduro yekupedzisira yekuwana vashandisi waya, GEPON ONU ichaita basa rakakosha mukuvakwa kwenetiweki kweNGN (Next Generation Network) mune ramangwana.

UTStarcom ONU 1001i inodhura-inoshanda mushandisi terminal michina inoshandiswa muGEPON masisitimu.Yakagadzirirwa vashandisi vekumba uye vashandisi veSOHO, uye inopa gigabit Broadband yekubatanidza yevashandisi magedhi uye / kana maPC.ONU 1001i inopa imwe 1000Base-TEthernet network port yedata uye IPTV vhidhiyo masevhisi.ONU1001i inogona kugadzirwa kure uye kutungamirirwa neUTStarcom BBS akatevedzana optical line terminal (OLT).

application

Iyo kumusoro kweONU 1001i yakabatana nehofisi yepakati (CO) kuburikidza neGEPON port, uye yakadzika ndeyevashandisi vega kana vashandisi veSOHO kupa 1 Gigabit Ethernet network port.Semhinduro yeramangwana yeFTTx, ONU 1001i inopa izwi rine simba, data-inomhanya uye masevhisi evhidhiyo kuburikidza ne-single-fiber GEPON.
