Waa maxay aaladda ONU?

ONU (Cutubka Shabakadda indhaha) unugga shabakadda indhaha, ONU waxa ay u qaybsantaa unugga shabakadda indhaha ee firfircoon iyo unugga shabakadda indhaha ee dadban.Guud ahaan, aaladaha ku qalabaysan la socodka shabakada oo ay ku jiraan kuwa qaata indhaha, gudbiyaasha indhaha ee kor u socda, iyo amplifiers buundada badan ayaa loo yaqaan noodhka indhaha.PON waxay isticmaashaa hal fiber indhaha si ay ugu xidho OLT, ka dibna OLT waxay ku xidhaa ONU.ONU waxay bixisaa adeegyo ay ka mid yihiin xogta, IPTV (tusaale, telefishinka is-dhexgalka), iyo codka (adoo isticmaalaya IAD, ie Integrated Access Device), oo si dhab ah u garanaya codsiyada "triple-play".

Astaamaha

Dooro inaad hesho xogta baahinta ee ay soo dirtay OLT;

Ka jawaab kala-duwanaanta iyo amarada xakamaynta awoodda ee ay soo saartay OLT;oo samee hagaajin u dhiganta;

Si buuxda ugu hoggaansan IEEE 802.3/802.3ah;

· Helitaanka dareenka ayaa ah mid aad u sarreeya -25.5dBm;

Gudbi awoodda ilaa -1 ilaa +4dBm;

PON waxay isticmaashaa hal fiber optic ah si ay ugu xidho OLT, ka dibna OLT waxay ku xidhaa ONU.ONU waxay bixisaa adeegyo ay ka mid yihiin xogta, IPTV (tusaale telefishan is-dhexgal ah), iyo cod (adoo isticmaalaya IAD, ie Aaladda Helitaanka Isku-dhafka ah), iyadoo ogaanaysa codsiyada "saddex-ciyaar";

Qiimaha ugu sarreeya PON: summetrical 10Gb/s xogta kor iyo hoos, codka VoIP iyo IP adeegyada;

ONU “qalabka oo ciyaar” ku salaysan helid toos ah iyo qaabayn;

Tayada sare ee adeega (QoS) ee ku salaysan biilasha heerka adeega (SLA);

Awoodaha maaraynta fog ee ay taageerayaan hodanka iyo shaqooyinka OAM ee xoogga leh;

Helitaanka iftiinka dareenka sare iyo isticmaalka tamarta iftiinka oo hooseeya;

· Taageer shaqada Dhimashada;

Kala soocidda

Iftiin firfircoon

Unugga shabakada indhaha ee firfircoon ayaa inta badan la adeegsadaa marka saddexda shabakadood la isku daro, waxayna isku daraan wax soo saarka RF-ga buuxa ee CATV;codka VOIP ee tayada sare leh;Habka saddex-lakabka ah ee marin-u-qaadista, marin-u-helidda wireless-ka iyo hawlaha kale, kuwaas oo si fudud u ogaan kara gelitaanka qalabka is-dhexgalka saddexda-ciyaar.

Iftiin dadban

Passive ONU (Optical Network Unit) waa aalad dhinaca adeegsadaha ah ee nidaamka GEPON (Gigabit Passive Optical Network), kaas oo loo isticmaalo in lagu joojiyo adeegyada laga gudbiyo OLT (Optical Line Terminal) iyada oo loo marayo EPON (Passive Optical Network).La shaqaynta OLT, ONU waxay siin kartaa adeegyo ballaadhan oo kala duwan isticmaalayaasha ku xidhan.Sida surfing internetka, VoIP, HDTV, VideoConference iyo adeegyo kale.ONU, oo ah aaladda dhinac-isticmaalka ee codsiyada FTTx, waa aalad-bandwidth-sare oo qiimo-ku-ool ah oo lagama maarmaanka u ah ka-guurka "xilligii fiilada naxaasta" una gudubta "xilligii fibre-gaab".Sida xalka kama dambaysta ah ee marin u helka fiilooyinka isticmaaleyaasha, GEPON ONU waxa ay door muhiim ah ka ciyaari doontaa dhismaha guud ee shabakadda NGN (Shabakadda Jiilka Xiga) mustaqbalka.

UTStarcom ONU 1001i waa qalab adeeg adeegeed kharash-ool ah oo loo isticmaalo nidaamyada GEPON.Waxaa loogu talagalay isticmaaleyaasha guriga iyo isticmaaleyaasha SOHO, waxayna siisaa isku xirka gigabit broadband ee albaabada isticmaalaha iyo/ama PC-yada.ONU 1001i waxay siisaa hal deked shabakad 1000Base-TEthernet ah oo loogu talagalay xogta iyo adeegyada fiidiyowga IPTV.ONU1001i waxa meel fog ka habayn kara oo maamuli kara UTStarcom BBS series optical line terminal (OLT).

codsi

Kordhinta sare ee ONU 1001i waxay ku xidhan tahay xafiiska dhexe (CO) iyada oo loo sii marayo dekedda GEPON, halka hoosena waxaa loogu talagalay isticmaaleyaasha gaarka ah ama isticmaaleyaasha SOHO si ay u bixiyaan 1 Gigabit Ethernet deked ah.Sida xalka mustaqbalka ee FTTx, ONU 1001i waxay bixisaa cod awood leh, xog xawaare sare leh iyo adeegyo fiidiyoow ah iyada oo loo marayo GEPON-fiber-kaliya.
