Qhov ntau yam kho kom zoo nkauj hauv kev tsim kev sib txuas lus kho qhov muag ua rau cov neeg siv khoom nrog qee cov ntsiab lus zoo sib xws.
FBT optical splitter vs PLC optical splitter
Muaj ob hom optical splitter hauv kev sib txuas lus hauv khw muag khoom lag luam: FBT optical splitter (fused tapered optical splitter) thiab PLC optical splitter (planar waveguide optical splitter).
Kev tsim cov khoom lag luam ntawm FBT optical splitter yog qhov pheej yig thiab yooj yim kom tau txais (piv txwv li, stainless hlau, optical fiber thiab kub ntsws lub raj yog txhua yam ntaub ntawv raw rau FBT optical splitter), thiab cov thev naus laus zis yog yooj yim, yog li tus nqi tsawg. PLC optical splitter siv semiconductor tshuab (lithography, etching, kev tsim kho tshuab), cov txheej txheem ntau lawm yog qhov nyuaj, tus nqi ntau dua li FBT optical splitter, tab sis kev ua haujlwm ntawm PLC optical splitter tseem ntseeg tau tshaj li FBT optical splitter.
Ib feeb n-optical splitter vs ob-point n-optical splitter
1-min-n optical splitter (n yog hais txog cov naj npawb ntawm cov chaw nres nkoj tawm) lossis 2-min-n optical splitter feem ntau siv hauv PON system. Ua li no, ib qho kev pom zoo rau lub zog tuaj yeem muab faib kom zoo rau txhua qhov chaw tso zis. Yog lawm, muaj cov kho qhov muag qhov hluav taws xob nrog kev sib faib tsis zoo ntawm lub zog hluav taws xob, tab sis hom optical splitter no yuav tsum tau kho kom haum thiab muaj nqi ntxiv, yog li nws tsis nquag. 1-N optical splitter los yog 2-N optical splitter yog siv nruab nrab ntawm ib kab davhlau ya nyob twg (OLT) thiab ntau lub network kho qhov muag (ont) kom paub qhov teeb tsa ntawm optical fiber lub cev sib koom los ntawm ib kis mus rau ntau lub ntsiab lus.
Qhov 2-dn optical splitter ntxiv cov caj qaum optical fiber ntau rau 1-min-n optical splitter. Hauv lwm lo lus, muaj ob lub ntsej muag hluav taws xob nruab nrab ntawm OLT thiab cov kho qhov muag splitter. Yog tias ib qho ntawm cov xov hluav taws xob tawg tau tawg, lwm lub fiber ntxiv yuav txuas ntxiv xa cov teeb liab ua ib qho fiber ntau. Piv txwv li, qhov chaw hauv nroog thaj chaw yog lub nplhaib cov qauv, yog li ob qho kawg ntawm tus txha nqaj qaum txuas tau txuas rau lub tswv yim kawg ntawm qhov kho qhov muag splitter. Yog tias ib qho fiber ntau tsis tuaj yeem xa cov teeb liab, lub teeb liab tuaj yeem txuas ntxiv mus rau lwm cov fiber. Hauv ib lo lus, 1-min-n optical splitter feem ntau yog siv hauv cov hnub qub network qauv, thiab 2-min-n optical splitter feem ntau yog siv nyob rau hauv lub nplhaib network qauv.
Optical splitter tuaj yeem pab cov neeg siv ua kom siab ua txoj haujlwm ntawm network kho qhov muag.
