I-ONU(iyunithi yenethiwekhi yokukhanya) indawo yokukhanya.I-ONUyahlulwe kwiyunithi yenethiwekhi esebenzayo kunye nelayibrari ye-passive optical network unit. Ngokuqhelekileyo, izixhobo ezixhotyiswe ngokubeka iliso kwinethiwekhi kubandakanya i-optical receiver, i-uplink optical transmitter kunye ne-multiple bridge amplifiers ibizwa ngokuba yi-optical node.
I-ONUUmsebenzi
1, Khetha ukufumana idatha yosasazo ethunyelwe yiOLT;
2, Phendula kuluhlu kunye nemiyalelo yolawulo lwamandla ekhutshwe yiOLT; kunye nokwenza uhlengahlengiso oluhambelanayo;
3, Gcina idatha ye-Ethernet yomsebenzisi kwaye uyithumele phezulu kwifestile yokuthumela eyabelweOLT.
I-ONUIzixhobo
Ukuthobela ngokupheleleyo IEEE 802.3/802.3ah
·Ukufumana ubuntununtunu ukuya kuthi ga -25.5dBm
·Dlulisa amandla ukuya kuthi ga ku -1 ukuya +4dBm
·I-PON isebenzisa i-fiber enye ye-optical ukudibanisa kwiOLT, kwaye emva koko iOLTidibanisa kwiI-ONU. I-ONUibonelela ngeenkonzo ezinje ngedatha, i-IPTV (oko kukuthi inethiwekhi yonxibelelwano kamabonakude), ilizwi (usebenzisa i-IAD, oko kukuthi iDivayisi yokuFikelela eDityanisiweyo) kunye nezinye iinkonzo, ukuqonda ngokwenene usetyenziso “lokudlala kathathu”
·Ixabiso eliphezulu le-PON: i-symmetrical 1Gb / s idatha ephezulu kunye nesezantsi, ilizwi leVoIP kunye neenkonzo zevidiyo ze-IP
·I-ONU"Plag kunye nokuDlala" ngokusekwe ekufumaneni okuzenzekelayo kunye noqwalaselo
·Umgangatho ophezulu wenkonzo (QoS) imisebenzi esekelwe kwisivumelwano somgangatho wenkonzo (SLA) ukubiza
·Izakhono zolawulo olukude ezixhaswa yimisebenzi etyebileyo nenamandla ye-OAM
·Ukufumana ukukhanya okunovakalelo oluphezulu kunye nokusetyenziswa kombane wokukhanya okuphantsi
·Inkxaso Dying Gasp umsebenzi
