Isebenza njani i-ONU

I-ONU yahlulwe yaba yiyunithi yenethiwekhi esebenzayo kunye neyunithi yenethiwekhi yokukhanya esebenzayo.
Ngokubanzi, izixhobo ezixhotyiswe ngabamkeli be-optical, i-uplink optical transmitters, kunye ne-amplifiers ezininzi zeebhulorho zokubeka iliso kwinethiwekhi ibizwa ngokuba yi-optical node.

Umsebenzi we-ONU
1. Khetha ukufumana idatha yosasazo ethunyelwe yiOLT;
2. Phendula kwimiyalelo yoluhlu kunye nolawulo lwamandla olukhutshwe yiOLT;kunye nokwenza uhlengahlengiso oluhambelanayo;
3. Buffer idatha ye-Ethernet yomsebenzisi kwaye uyithumele kwicala elingasentla kwifestile yokuthumela eyabiwe yiOLT.
Ihambelana ngokupheleleyo ne-IEEE 802.3/802.3ah
Fumana ubuntununtunu ukuya kuthi ga kwi -25.5dBm
Dlulisa amandla ukuya kuthi ga ku -1 ukuya +4dBm
I-fiber eyodwa ebonakalayo ibonelela ngeenkonzo ezifana nedatha, i-IPTV, kunye nelizwi, kwaye iqonda ngokwenene usetyenziso "lokudlala kathathu".
·Izinga eliphezulu le-PON: i-uplink kunye ne-downlink symmetrical 1Gb/s data, ilizwi leVoIP kunye neenkonzo zevidiyo ze-IP.i
I-ONU "iplagi kunye nokudlala" ngokusekelwe ekufumaneni ngokuzenzekelayo kunye noqwalaselo
Umgangatho oPhezulu weNkonzo (QoS) iimpawu ezisekelwe kwiSivumelwano seNqanaba lokuhlawula iSivumelwano (i-SLA).
Izakhono zolawulo olukude ezixhaswa yimisebenzi etyebileyo nenamandla ye-OAM
Ukufumana ukukhanya okunovakalelo oluphezulu kunye nokusetyenziswa kombane wokukhanya okuphantsi
Inkxaso Dying Gasp umsebenzi
Iyunithi yenethiwekhi yamehlo esebenzayo
Iyunithi esebenzayo yenethiwekhi ye-optical network isetyenziswa ikakhulu ekudityanisweni kweenethiwekhi ezintathu.Idibanisa imveliso ye-CATV epheleleyo ye-RF;i-audio ye-VOIP ephezulu;Imowudi yoluhlu oluthathu, ukufikelela ngaphandle kwamacingo kunye neminye imisebenzi, kwaye iqonda ngokulula ukufikelela kwesixhobo se-terminal sokudityaniswa kwenethiwekhi kathathu.
IYunithi yeNethiwekhi yePassive Optical
Iyunithi yenethiwekhi ye-passive optical network sisixhobo esisecaleni komsebenzisi se-GPON (Gigabit Passive Optical Network) inkqubo, kwaye isetyenziselwa ukuphelisa iinkonzo ezithunyelwa kwi-OLT (i-Optical Line Terminal) ngePON (Passive Optical Network).Ukusebenzisana ne-OLT, i-ONU inokubonelela ngeenkonzo ezahlukeneyo ze-broadband kubasebenzisi abaxhunyiwe.Okufana nokusefa kwi-Intanethi, iVoIP, iHDTV, iNkomfa yeVidiyo kunye nezinye iinkonzo.Njengesixhobo somsebenzisi wesicelo se-FTTx, i-ONU i-high-bandwidth kunye neendleko ze-terminal device eziyimfuneko ekutshintsheni ukusuka "kwixesha le-copper cable" ukuya kwi-"optical fiber era".Njengesisombululo esiphezulu sokufikelela kwingcingo yabasebenzisi, i-GPON ONU iya kudlala indima ebalulekileyo kulwakhiwo lwenethiwekhi ngokubanzi ye-NGN (Inethiwekhi yesiZukulwana esilandelayo) kwixesha elizayo.
I-HG911 ONU sisixhobo setheminali somsebenzisi esineendleko eziphezulu zenkqubo ye-xPON.Yenzelwe abasebenzisi basekhaya kunye nabasebenzisi be-SOHO, ukubonelela nge-gigabit-speed broadband uxhumano kumasango omsebenzisi kunye / okanye iiPC.I-ONU inikeza enye i-1000Base-T Ethernet port yedatha kunye neenkonzo zevidiyo ze-IPTV.Iyakwazi ukucwangciswa kude kwaye ilawulwe yi-HUANET series optical line terminal (OLT).
Usetyenziso
I-ONU ekhuphukayo idibanisa kwiofisi ephakathi (CO) ngokusebenzisa i-xPON port, kunye nokuziphatha okuphantsi kunika i-port ye-Gigabit Ethernet kubasebenzisi ngabanye okanye abasebenzisi be-SOHO.Njengesisombululo sexesha elizayo se-FTTx, i-ONU 1001i inikezela ngelizwi elinamandla, idatha yesantya esiphezulu kunye neenkonzo zevidiyo nge-fiber eyodwa ye-GEPON.
