Yuav ua li cas xaiv homkab ncua kev pom kev zooODL
Cov Kab Ncua Kev Ncua Kev Pom Kev (ODL) yog cov khoom siv ua haujlwm uas tso cai rau cov teeb liab kho qhov muag kom nkag los ntawm qhov kawg ntawm fiber, xa mus rau qee qhov ntev ntawm qhov chaw dawb, thiab tom qab ntawd sau ntawm qhov kawg ntawm fiber rau cov zis, ua rau lub sijhawm qeeb. Lawv tuaj yeem siv rau hauv cov tes hauj lwm sib txuas lus ceev xws li PMD compensation, interferometric sensors, coherent telecommunications, spectrum analyzers, thiab OCT systems.
Xaiv qhov tsim nyogfiber optic qeeb kabyuav tsum xav txog ntau yam, suav nrog lub sijhawm qeeb, bandwidth, kev poob, cov xwm txheej ib puag ncig, thiab cov kev xav tau ntawm cov ntawv thov tshwj xeeb. Nov yog qee cov kauj ruam tseem ceeb thiab kev xav txog los pab koj xaiv qhov tsim nyogkab qeeb fiber:
1. Lub sijhawm ncua: Txheeb xyuas lub sijhawm ncua uas xav tau raws li qhov xwm txheej ntawm daim ntawv thov tshwj xeeb.
2. Bandwidth Range: Cov ntawv thov sib txawv yuav muaj cov kev xav tau bandwidth sib txawv. Piv txwv li, cov kab ke sib txuas lus feem ntau xav tau bandwidth dav, thaum qee lub radar systems tsuas yog xav tau cov cim hauv ib qho zaus tshwj xeeb. Tsis tas li ntawd, nws yog qhov tsim nyog los xav txog cov yam ntxwv bandwidth sib txawv ntawm cov fiber ntau hom thiab ntau hom fiber. Ib hom fiber yog qhov tsim nyog rau kev siv ntev thiab bandwidth siab, thaum multimode fiber yog qhov tsim nyog rau kev siv luv luv.
3 Cov kev cai rau kev poob: Txheeb xyuas qhov siab tshaj plaws uas tso cai rau kev poob raws li cov kev cai ntawm daim ntawv thov. Hauv kev siv tiag tiag, cov fibers optical uas poob qis thiab cov connectors zoo yuav raug xaiv los txo qhov teeb liab attenuation.
4 Tej yam kev mob ib puag ncig: Qee qhov kev siv yuav xav tau kev ua haujlwm ntawm qhov kub thiab txias heev, yog li xaiv cov fiber ntau uas tuaj yeem ua haujlwm ib txwm nyob rau hauv qhov kub thiab txias uas tau teev tseg. Tsis tas li ntawd, nyob rau hauv qee qhov chaw ib puag ncig, cov fiber ntau yuav tsum muaj qee lub zog kho tshuab kom tiv thaiv kev puas tsuaj.
5. Cov nqi siv nyiaj: Xaiv cov kab qeeb qeeb optic uas pheej yig raws li cov peev nyiaj. Cov kab qeeb qeeb fiber ntau ua haujlwm tau zoo yuav kim, tab sis lawv tsim nyog rau qee qhov kev siv tseem ceeb.
6 Cov xwm txheej tshwj xeeb ntawm daim ntawv thov: Nkag siab txog cov kev xav tau tshwj xeeb ntawm cov xwm txheej tshwj xeeb ntawm daim ntawv thov, xws li seb puas xav tau kev ncua sijhawm hloov kho tau, seb puas yuav tsum muaj lwm yam haujlwm (xws li cov amplifiers, cov lim dej, thiab lwm yam) koom ua ke. Hauv ntej, kev xaiv cov kab fiber optic qeeb kom zoo yuav tsum tau xav txog ntau yam. Peb vam tias cov kauj ruam saum toj no thiab cov yam ntxwv tuaj yeem pab koj xaiv cov kab optic qeeb ODL kom zoo.
