Optical splitter tseem hu ua optical splitter, uas yog kev sib txuas ntawm kev sib faib ntawm cov khoom sib txuas ntawm lub zog uas tuaj yeem sib cais cov tswv yim teeb pom kev zoo rau ob lossis ntau qhov tawm ntawm cov cim kho qhov muag. Kho qhov muag splitter yog ib hom khoom siv passive. Tsis muaj cov khoom siv hluav taws xob sab hauv lossis cov khoom siv fais fab. Nws yog ib qho tseem ceeb ntawm qhov ntsuas qhov ua haujlwm zoo (xws li EPON, GPON, BPON, FTTx, FTTH, thiab lwm yam). Tam sim no, kev faib ua feem ntawm cov khoom tawg tshwj xeeb yog feem ntau 1: 4, 1: 8, 1:16, thiab 1:32.
Hauv cov txheej txheem WDM, kev ua haujlwm ntawm lub demultiplexer yog los faib cov cim kho qhov muag ntawm cov sib txawv ntawm cov yoj yob mus rau qhov sib phim wavelength; thaum lub kho qhov muag tawg tau muab faib tag nrho cov teeb liab kho qhov muag mus rau ntau txoj hauv kev rau kev sib kis. Lub kho qhov muag cais tau muab faib tawm ntawm cov teeb meem kho qhov muag tau ua rau ntau cov zis kho qhov muag ua ke nrog qee qhov sib cais tshwj xeeb. Piv txwv, lub tshuab hluav taws xob sib cais uas muaj qhov sib cais ntawm 1: 4 tuaj yeem faib cov teeb liab hluav taws xob mus rau plaub qhov sib luag, thiab tom qab ntawd xa mus rau hauv plaub yam sib txawv. Tsis tas li ntawd, kho qhov muag tawg kuj tuaj yeem raug txiav tawm nrog ntau hom txuas txuas. Cov txheej txheem ntim khoom feem ntau yog thawv hom lossis stainless hlau raj hom. Lub thawv hom optical splitters feem ntau siv 2 hli lossis 3mm sab nraud qhov kho qhov muag ntsia hlau, thaum hlau stainless raj hom Optical splitters feem ntau siv cov kho qhov muag hluav taws xob uas muaj qhov dav sab nraud ntawm 0.9 hli.
