Ko te ONU (Wāhanga Whatunga Whatu) he wāhanga whatunga whatu, kua wehea te ONU ki te wāhanga whatunga whatu hohe me te wāhanga whatunga whatu kore. Ko te tikanga, ko ngā taputapu e mau ana i te aroturuki whatunga tae atu ki ngā kaiwhiwhi whatu, ngā tuku whatu whakarunga, me ngā whakakaha piriti maha e kiia ana ko ngā pūnga whatu. Ka whakamahia e te PON he muka whatu kotahi hei hono atu ki te OLT, kātahi ka hono atu te OLT ki te ONU. Ka whakaratohia e te ONU ngā ratonga pēnei i te raraunga, te IPTV (arā, te pouaka whakaata whatunga tauwhitiwhiti), me te reo (mā te whakamahi i te IAD, arā, te Pūrere Uru Whakauru), e tino whakatutuki ana i ngā tono "takaro-toru".
Ngā Āhuatanga
Kōwhiria kia whiwhi i ngā raraunga pāho i tukuna e te OLT;
Whakautu ki ngā whakahau awhe me te whakahaere mana i tukuna e te OLT; me te mahi i ngā whakarerekētanga e rite ana;
Puritia ngā raraunga Ethernet a te kaiwhakamahi, ka tukuna ki te awa whakarunga i te matapihi tuku kua tohaina e te OLT;
Kia tutuki katoa ngā whakaritenga o te IEEE 802.3/802.3ah;
·Ko te aro o te whiwhi he teitei ki te -25.5dBm;
·Ka taea te tuku mana ki te -1 ki te +4dBm;
Ka whakamahia e te PON tētahi muka whatu kotahi hei hono atu ki te OLT, kātahi ka hono atu te OLT ki te ONU. Ka whakaratohia e te ONU ngā ratonga pēnei i te raraunga, te IPTV (arā, te pouaka whakaata whatunga tauwhitiwhiti), me te reo (mā te whakamahi i te IAD, arā, te Pūrere Uru Whakauru), e whakatinana ana i ngā tono "takaro-toru";
·PON tere teitei rawa: raraunga whakarunga me te whakararo 10Gb/s ōrite, ratonga reo VoIP me te ataata IP;
·Te "mono me te purei" a te ONU i runga i te kimi me te whirihoranga aunoa;
·Ngā mahi kounga ratonga matatau (QoS) i runga i te utu whakaaetanga taumata ratonga (SLA);
·Ngā āheinga whakahaere mamao e tautokona ana e ngā mahi OAM whai rawa me te kaha;
·Te whiwhi mārama tairongo teitei me te iti o te kaha o te rama whakauru;
·Tautoko i te mahi Dying Gasp;
Whakarōpūtanga
Mārama hohe
Ko te waeine whatunga whatu hohe e whakamahia ana i te nuinga o te wā ina whakauruhia ngā whatunga e toru, ā, ka whakauruhia e ia te putanga RF roopu-katoa CATV; te oro VOIP kounga teitei; te aratau ara toru-paparanga, te urunga ahokore me ētahi atu mahi, ka taea te whakatutuki i te urunga taputapu whakaurunga takaro-toru.
Mārama kore mahi
Ko te ONU Whakangāwari (Wāhanga Whatunga Whatu) he taputapu taha-kaiwhakamahi o te pūnaha GEPON (Whatunga Whatu Whakangāwari Gigabit), e whakamahia ana hei whakamutu i ngā ratonga e tukuna ana mai i te OLT (Wāhanga Raina Whatu) mā te EPON (Whatunga Whatu Whakangāwari). Mā te mahi tahi me te OLT, ka taea e te ONU te whakarato i ngā ratonga whānui ki ngā kaiwhakamahi hono. Pēnei i te tirotiro Ipurangi, VoIP, HDTV, Hui Ataata me ētahi atu ratonga. Ko te ONU, hei taputapu taha-kaiwhakamahi mō ngā tono FTTx, he taputapu mutunga whānui-rahi me te utu-pai e tika ana mō te whakawhiti mai i te "wā taura parahi" ki te "wā muka whatu". Hei otinga tino pai mō te urunga waea a ngā kaiwhakamahi, ka whai wāhi nui te GEPON ONU ki te hanganga whatunga whānui o te NGN (Whatunga Whakatupuranga e whai ake nei) ā muri ake nei.
He taputapu taunga kaiwhakamahi utu-pai te UTStarcom ONU 1001i e whakamahia ana i roto i ngā pūnaha GEPON. He mea hanga mō ngā kaiwhakamahi kāinga me ngā kaiwhakamahi SOHO, ā, e whakarato ana i ngā hononga whānui gigabit mō ngā kuwaha kaiwhakamahi me/ranei ngā PC. E whakarato ana te ONU 1001i i tētahi tauranga whatunga 1000Base-TEthernet mō ngā ratonga raraunga me ngā ratonga ataata IPTV. Ka taea te whirihora me te whakahaere mamao i te ONU1001i e te taunga raina whatu raupapa BBS UTStarcom (OLT).
tono
Ko te taha whakarunga o ONU 1001i e hono ana ki te tari matua (CO) mā te tauranga GEPON, ā, ko te taha whakararo mā ngā kaiwhakamahi takitahi, mā ngā kaiwhakamahi SOHO rānei e whakarato te tauranga whatunga 1 Gigabit Ethernet. Hei otinga ā muri ake nei mō te FTTx, ka whakarato a ONU 1001i i ngā ratonga reo kaha, raraunga tere-teitei me ngā ratonga ataata mā te muka-kotahi GEPON.
