    OLT kunye ONU

    Ixesha lokuposa: Jun-14-2024

    Inethiwekhi yokufikelela kwi-Optical (oko kukuthi, uthungelwano lofikelelo olunokukhanya njengesixhobo sothumelo, endaweni yocingo lobhedu, lusetyenziselwa ukufikelela kusapho ngalunye. Inethiwekhi yokufikelela kwi-Optical).Uthungelwano lofikelelo olubonayo ngokubanzi lunamacandelo amathathu: i-terminal yomgca wokukhanyaOLT, iyunithi yenethiwekhi yamehloI-ONU, inethiwekhi yokusasazwa kwamehloI-ODN,apho kuOLT kwayeI-ONUngamacandelo angundoqo othungelwano lofikelelo lwamehlo

    OLTimele i-Optical Line Terminal.OLTsisixhobo se-optical line, sisixhobo se-ofisi yonxibelelwano, sisetyenziselwa ukuqhagamshela isiqu sefiber optical, indima ilinganatshintshaor umzilakuthungelwano lonxibelelwano lwemveli, sisixhobo sokungena kwinethiwekhi yangaphandle kunye nokungena kwenethiwekhi yangaphakathi. Ibekwe kwisiphelo sendawo, eyona misebenzi ibalulekileyo yesigqeba kukucwangciswa kwetrafikhi, ulawulo lwe-buffer, kunye nokubonelela nge-interface ejongene nomsebenzisi i-passive fiber network kunye nokwabiwa kwe-bandwidth. Ukubeka nje, kukufezekisa imisebenzi emibini, phezulu, ukugqiba ukufikelela phezulu kwenethiwekhi yePON; Ezantsi, idatha efunyenweyo ithunyelwa kubo bonkeI-ONUizixhobo zeterminal yomsebenzisi ngenethiwekhi yeODN.

    I-ONUyiYunithi yeNethiwekhi yokubona.I-ONUinemisebenzi emibini: ukwamkela ngokukhetha usasazo oluthunyelwe nguOLT, kunye nokufumana impendulo kwiOLTukuba idatha kufuneka yamkelwe; Qokelela kwaye ugcine idatha ye-Ethernet ekufuneka umsebenzisi ayithumele, kwaye uthumele idatha egcinwe kwi-cacheOLTisiphelo sendlela ngokwefestile yokuthumela eyabelweyo.

    Kwinethiwekhi ye-FTTx (cofa apha Ukufunda ngokukhawuleza ngeFTTx), iI-ONUindlela yofikelelo iyahluka ngobeko olwahlukileyo. Umzekelo, iFayibha ukuya kwiCurb (FTTC): II-ONUibekwe kwigumbi lezixhobo ezisembindini weseli. I-FTTB(IFayibha ukuya kwiSakhiwo) :I-ONUibekwe kwi-terminal box yepaseji; FTTH(IFayibha ukuya eKhaya): II-ONUibekwe kumsebenzisi wasekhaya.

    OLTyitheminali yolawulo,I-ONUyitheminali; Ukuvulwa kwenkonzo yeI-ONUihanjiswa ngeOLT, yaye ulwalamano phakathi kwabo babini yinkosi nekhoboka. EzininziIi-ONUinokudityaniswa kwiOLTngokusebenzisa isiqhekeza.

    I-ODN yiNethiwekhi ye-Optical Distribution, inethiwekhi yokusabalalisa optical, umjelo womzimba wokuhanjiswa kwe-optical phakathiOLTkwayeI-ONU. Umsebenzi wayo oyintloko kukugqiba ukuhanjiswa kwe-bidirectional yezibonakaliso ze-optical. Ngokuqhelekileyo iqulunqwe nge-fiber optical kunye nekhebula, i-optical connector, i-optical splitter, kunye nezixhobo ezincedisayo ukufaka kunye nokudibanisa ezi zixhobo. Elinye lawona macandelo abalulekileyo yi-optical splitter.

    HDVinokubonelela abathengi ngoluhlu olupheleleyo lweemveliso zeFTTH kunye nezisombululo. Yasekwa kwi-2012, i-HDV ngumboneleli wesisombululo esisodwa kunye ne-ODM & ne-OEM umenzi we-fiber access networks. Ngokweemfuno zabathengi, sinako ukuncedisa abathengi ukuba bayile izikimu zoyilo lwemveliso enexabiso elisebenzayo kunye neemveliso ezilungiselelweyo, kunye nokubonelela ngesiqinisekiso somgangatho we-ODM & neenkonzo ze-OEM. Ibe ibambelele kumoya wobunye, ukusebenza nzima, ukusungula izinto ezintsha, ukusebenza kakuhle kunye nokuthembeka, kunye nobuchule obunamandla be-R & D kunye nenkqubo yonikezelo egqibeleleyo, ukubonelela abathengi ngezixhobo zonxibelelwano ezikumgangatho ophezulu kunye nezisombululo zobugcisa, masisebenze. kunye, win-win ikamva!
