    Yintoni i-splitter ye-optical kwaye zeziphi iimpawu ezibalulekileyo zobugcisa?

    Ixesha lokuposa: Mar-19-2021

    I-optical splitter yenye yezixhobo ezibalulekileyo ze-passive kwikhonkco ye-fiber optical, kwaye ikakhulu idlala indima yokwahlula. Isetyenziswa ngokubanzi kwitheminali yomgca wokukhanyaOLTkunye ne-terminal yenethiwekhi ye-optical networkI-ONUyothungelwano lwe-optical yokwenziwa ukuqaphela ukwahlula kophawu lokukhanya.

    I-splitter ye-optical isasaza isignali ye-optical edlulisiweyo kwifiber enye ye-optical fibers optical fibers. Kukho iintlobo ezininzi zokusabalalisa, 1 × 2, 1 × 4, 1 × N, okanye 2 × 4, M × N. Uyilo oluqhelekileyo lweFTTH lu:OLT(Isiphelo seofisi yegumbi lekhompyuter)-ODN (inkqubo yokuhambisa inethiwekhi ye-passive optical)-I-ONU(isiphelo somsebenzisi), apho i-optical splitter isetyenziswa kwi-ODN ukuqonda ukuba abasebenzisi abaninzi bokugqibela babelane ngojongano lwePON enye. Kwisakhiwo se-PON, xa ukuhanjiswa kwezakhiwo zihlakazekile kwaye zingaqhelekanga, ezifana nokuhanjiswa kwee-villas, umgama ude, kwaye ubuninzi babasebenzisi buphantsi, indlela yokwahlula i-centralized inokusebenzisa ngokupheleleyo izibonelelo kwaye igubungele indawo engqongileyo.

    Inye kuphela isahluli samehlo esinokusetyenziswa kumsebenzi wothungelwano obonakalayo, okanye izahluli zamehlo ezininzi ezinokuthi zisetyenziswe kunye ukwahlula iisignali zamehlo.

    Iimpawu zokusebenza ezichaphazela i-optical splitter zihlala zilandelayo:

    Ilahleko yokufaka

    Ilahleko yokufaka i-fiber splitter ibhekisela kwinani le-dB yesiphumo ngasinye ngokumalunga nokulahlekelwa kwe-optical input. Ngokuqhelekileyo, incinci ixabiso lelahleko lofakelo.

    Ukwahlula umlinganiselo

    Umlinganiselo wokwahlula uchazwa njengomlinganiselo wamandla ophumayo kwizibuko ngalinye lemveliso yefiber splitter. Ngokubanzi, umlinganiselo wokuqhekeka we-PLC optical splitter usasazwa ngokulinganayo, kwaye umlinganiselo wokwahlula we-tapered tapered optical splitter unokungalingani.

    Ukumiselwa komlinganiselo othile womlinganiselo wokwahlula unxulumene nobude bokukhanya okuhanjiswayo. Ngokomzekelo, xa isebe le-optical lihambisa ukukhanya kwe-micron eyi-1.31, umlinganiselo wokuhlukana kweziphelo ezimbini zemveliso ngu-50:50; xa uhambisa 1.5μm ukukhanya, kuba yi-70: 30 (Isizathu sokuba oku kwenzekayo kukuba i-fiber splitter ine-bandwidth ethile, oko kukuthi, i-bandwidth yesignali ye-optical idluliselwe xa umlinganiselo wokuhlukana ungatshintshi ngokusisiseko).

    Ukubekwa wedwa

    Ukwahlukaniswa kubhekiselele kwisakhono sokuzihlukanisa kwendlela enye ye-optical fiber splitter ukusuka kwimiqondiso ye-optical kwezinye iindlela ze-optical.

    Buyisela ilahleko

    Ilahleko yokubuyisela, ebizwa ngokuba yi-reflection loss, ibhekisela ekulahlekelweni kwamandla e-optical signal ebuyisiweyo okanye ebonakaliswe ngokuyeka kwi-fiber okanye umgca wokuhambisa.

    Inkulu ilahleko yembuyekezo, ngcono, ukunciphisa impembelelo yokukhanya okubonakalisiweyo kumthombo wokukhanya kunye nenkqubo.

    Ukongezelela, ukufana, ukuqondisa, ukulahleka kwe-PDL ye-polarization, njl. I-Optical fiber splitter yenye yezona zixhobo zibaluleke kakhulu kwikhonkco yefiber optical, kwaye ifaneleke ngakumbi ukudibanisa i-MDF kunye nezixhobo ze-terminal kwiinethiwekhi ze-optical passive (EPON, GPON, BPON, FTTX, FTTH, njalo njalo) ukuhambisa imiqondiso yokubona.
