Yintoni isixhobo se-ONU?

I-ONU (iYunithi yeNethiwekhi yokubona) iyunithi yenethiwekhi yokukhanya, i-ONU yahlulwe yaba yiyunithi yenethiwekhi esebenzayo kunye neyunithi yothungelwano olubonakalayo.Ngokubanzi, izixhobo ezixhotyiswe ngokujongwa kwenethiwekhi kubandakanya abamkeli be-optical, ii-transmitter zamehlo ezinyukayo, kunye ne-amplifiers ezininzi zebhulorho zibizwa ngokuba zii-optical nodes.I-PON isebenzisa i-fiber eyodwa ye-optical ukudibanisa kwi-OLT, kwaye i-OLT idibanisa kwi-ONU.I-ONU ibonelela ngeenkonzo ezifana nedatha, i-IPTV (oko kukuthi umabonakude wonxibelelwano osebenzisanayo), kunye nelizwi (usebenzisa i-IAD, oko kukuthi, iDivayisi yokuFikelela eDityanisiweyo), ukuqonda ngokwenene usetyenziso “lokudlala kathathu”.

Iimbonakalo

Khetha ukufumana idatha yosasazo ethunyelwe yiOLT;

Phendula kuluhlu kunye nemiyalelo yolawulo lwamandla ekhutshwe yiOLT;kunye nokwenza uhlengahlengiso oluhambelanayo;

Cache idatha ye-Ethernet yomsebenzisi kwaye uyithumele phezulu kwifestile yokuthumela eyabiwe yiOLT;

Ukuthobela ngokupheleleyo IEEE 802.3/802.3ah;

·Ukufumana ubuntununtunu buphezulu njenge -25.5dBm;

·Hambisa amandla ukuya ku--1 ukuya +4dBm;

I-PON isebenzisa i-fiber eyodwa ye-optical ukudibanisa kwi-OLT, kwaye i-OLT idibanisa kwi-ONU.I-ONU ibonelela ngeenkonzo ezifana nedatha, i-IPTV (oko kukuthi umabonakude wonxibelelwano wonxibelelwano), kunye nezwi (usebenzisa i-IAD, oko kukuthi, iDivaysi yokuFikelela eDityanisiweyo), ukuqonda izicelo “zokudlala kathathu”;

·Izinga eliphezulu le-PON: i-symmetrical 10Gb / s idatha ephezulu kunye nezantsi, ilizwi leVoIP kunye neenkonzo zevidiyo ze-IP;

I-ONU "iplagi kunye nokudlala" ngokusekelwe ekufumaneni okuzenzekelayo kunye noqwalaselo;

·Umgangatho ophezulu wenkonzo (QoS) imisebenzi esekelwe kwintlawulo yesivumelwano somgangatho wenkonzo (SLA);

·Amandla olawulo olukude axhaswa yimisebenzi etyebileyo nenamandla ye-OAM;

·Ukwamkelwa kokukhanya okunovakalelo okuphezulu kunye nokusetyenziswa kombane kokukhanya okuphantsi;

·Ukuxhasa umsebenzi weGasp yokuFa;

Ukuhlelwa

Ukukhanya okusebenzayo

Iyunithi yothungelwano olubonakalayo olusebenzayo lusetyenziswa ikakhulu xa uthungelwano oluthathu ludityanisiwe, kwaye ludibanisa imveliso yeRF ye-CATV epheleleyo;i-audio ye-VOIP ephezulu;Imowudi yomzila enemigangatho emithathu, ukufikelela ngaphandle kwamacingo kunye neminye imisebenzi, enokuqonda ngokulula ukufikelela kwesixhobo sokudibanisa imidlalo emithathu.

Ukukhanya okungahambiyo

I-Passive ONU (i-Optical Network Unit) yinkqubo yecala lomsebenzisi ye-GEPON (i-Gigabit Passive Optical Network), esetyenziselwa ukuphelisa iinkonzo ezithunyelwa kwi-OLT (i-Optical Line Terminal) nge-EPON (i-Passive Optical Network).Ukusebenzisana ne-OLT, i-ONU inokubonelela ngeenkonzo ezahlukeneyo ze-broadband kubasebenzisi abaxhunyiwe.Okufana nokusefa kwi-Intanethi, iVoIP, iHDTV, iVideoConference kunye nezinye iinkonzo.I-ONU, njengesixhobo secala lomsebenzisi kwizicelo ze-FTTx, i-high-bandwidth kunye neendleko ze-terminal device eziyimfuneko ekutshintsheni ukusuka kwi "copper cable era" ukuya kwi "optical fiber era".Njengesona sisombululo sokufikelela kwiintambo zabasebenzisi, i-GEPON ONU iya kudlala indima ebalulekileyo kulwakhiwo lwenethiwekhi ngokubanzi ye-NGN (Inethiwekhi yesiZukulwana esilandelayo) kwixesha elizayo.

I-UTStarcom ONU 1001i sisixhobo esinexabiso eliphezulu somsebenzisi esisetyenziswa kwiinkqubo zeGEPON.Yenzelwe abasebenzisi basekhaya kunye nabasebenzisi be-SOHO, kwaye ibonelela ngoqhagamshelwano lwe-gigabit broadband kumasango omsebenzisi kunye / okanye iiPC.I-ONU 1001i inikeza enye i-1000Base-TEthernet port yenethiwekhi yedatha kunye neenkonzo zevidiyo ze-IPTV.I-ONU1001i inoqwalaselo ekude kwaye ilawulwe yi-UTStarcom BBS series optical line terminal (OLT).

isicelo

Umlambo ophezulu we-ONU 1001i uqhagamshelwe kwiofisi ephakathi (CO) nge-port ye-GEPON, kwaye i-downstream yabasebenzisi ngabanye okanye abasebenzisi be-SOHO ukubonelela nge-1 Gigabit Ethernet port port.Njengesisombululo sexesha elizayo se-FTTx, i-ONU 1001i inikezela ngelizwi elinamandla, idatha yesantya esiphezulu kunye neenkonzo zevidiyo nge-single-fiber GEPON.
