I-optical splitter yenye yezixhobo ezibalulekileyo ze-passive kwikhonkco ye-fiber optical, kwaye ikakhulu idlala indima yokwahlula.Ngokuqhelekileyo isetyenziswa kwi-terminal ye-OLT ye-optical line kunye ne-terminal ye-intanethi ye-ONU ye-passive network optical ukuqonda ukwahlula isignali yokukhanya.
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. I-architecture ngokubanzi yeFTTH yile: OLT (isiphelo seofisi yekhompyutha) -ODN (i-passive optical network distribution system )-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 ephakathi 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.
