Qhov Kho Kom Zoo Nkauj Sib Tw Rau Cov Kev Siv FTTX
Lub fiber ntau lub tshuab hluav taws xob yog qhov tseem ceeb tshaj dhau los uas siv rau hauv cov khoos phis tawm kho qhov muag kom ua tiav qhov kho qhov muag ua ke ', txuas, thiab faib, tsuas yog tib yam nrog cov coacial cable kis tau. Ib lub tshuab hluav taws xob sib cais yog cov cuab yeej siv optical tandem nrog ntau lub ntshuam lossis tsim cov khoom siv. Feem ntau peb siv M x N los qhia qhov splitter nrog M ntshuam thiab N tawm cov naj npawb. Cov hluav taws xob sib cais uas siv nyob rau hauv CATV cov kab ke, feem ntau 1 x 2, 1 x 3 lossis 1 x N fiber cais uas tau tsim los ntawm lawv.
Fiber optic splitter yog qhov sib txig sib xyaw rau FTTH PON (passive optical network). Gigabit Ethernet Passive Optical Network (GPON) cov sib cais sib koom ua lub luag haujlwm tseem ceeb hauv Fiber rau Lub Tsev (FTTH) tes hauj lwm los ntawm kev tso cai rau PON network nkaus xwb los sib koom nrog ntau tus neeg siv. Kev siv tes hauj lwm siv BPON, GPON, EPON, 10G EPON, thiab 10G GPON thev naus laus zis txhua qhov siv cov khoom sib cais yooj yim no.
Txhua qhov khoos phis tawm dhau los, tsis muaj teeb meem GPON, EPON cov tshuab muaj los ntawm Optical Line Termination (OLT), Optical Network Unit (ONU) thiab Optical Distribution Network (ODN). ODN yog qhov tseem ceeb tshaj plaws yog FTTx systems uas yog cov channel ntawm lub cev ntawm lub tshuab xa tawm kho qhov muag ntawm OLT thiab ONU. Nws yog tsim los ntawm cov hluav taws xob fiber ntau kho qhov muag, txuas hluav taws xob, thiab tseem ceeb tshaj, cov cuab yeej siv hluav taws xob zoo ntxiv rau cov khoom siv hluav taws xob txuas cov cuab yeej no.
Muaj ob lub hauv paus ua kom muaj cov tshuab tsim hluav taws xob rau kev sib kis zoo: Fused Biconical Taper (FBT) thiab Planar Lightwave Circuit (PLC), uas sib haum rau hom fiber ntau splitterers, FBT splitter, kuj paub zoo li FBT txuas ntxiv, thiab PLC splitter. Fused Biconical Taper yog cov thev naus laus zis qub thiab feem ntau qhia cov kev poob ntau dua li cov PLC tshiab uas rho tawm.
Lub PLC Splitter tsis muaj cov khoom siv hluav taws xob thiab siv tsis muaj zog. ob qho PLC thiab FBT splitters siv nyob rau hauv PON tes hauj lwm. Ib lub PON network yuav raug tsim nrog ib lub tshuab hluav taws xob uas muaj qhov sib cais, lossis nws tuaj yeem muaj ob lossis ntau qhov chaw sib cais ua ke. Txij li thaum txhua qhov kev sib txuas kho qhov muag yuav ntxiv cov yeeb yaj kiab kho qhov muag, ib tus splitter tsuas yog qhov zoo dua rau ntau cov khoom sib txuas. Ib qho txuas txuas ntxiv (thiab cov peev xwm) tau qhia rau hauv kev sib txuas ntawm ob txoj kev sib cais ua ke.
Nrog kev nkag mus rau lub network kev tsim kho nkag mus thiab cov neeg tuaj yeem nce ntxiv hauv kev ua lag luam. PLC splitter yuav tsis muaj ob zaug los ua lub zog tseem ceeb hauv kev ua lag luam, PLC optical splitters muaj cov yam ntxwv ntawm digitization, network, broadband, miniaturization thiab yooj yim txij nkawm, thiab lwm yam.
