Yuav ua li cas xaiv homoptical ncua kabODL
Optical Delay Kab (ODL) yog cov khoom siv ua haujlwm uas tso cai rau cov teeb liab kho qhov muag los ntawm qhov kawg ntawm fiber ntau, kis tau los ntawm qhov ntev ntawm qhov chaw dawb, thiab tom qab ntawd sau rau ntawm qhov kawg ntawm fiber ntau rau cov zis, uas ua rau lub sijhawm qeeb. Lawv tuaj yeem siv rau hauv kev sib txuas lus ceev ceev xws li PMD them nyiaj, interferometric sensors, coherent telecommunications, spectrum analyzers, thiab OCT systems.
Xaiv qhov tsim nyogfiber optic ncua kabyuav tsum xav txog ntau yam, suav nrog lub sijhawm ncua sijhawm, bandwidth, poob, ib puag ncig, thiab kev thov tshwj xeeb scenario. Nov yog qee cov kauj ruam tseem ceeb thiab kev txiav txim siab los pab koj xaiv qhov tsim nyogfiber ncua kab:
1. Lub sij hawm ncua sij hawm: Txiav txim siab lub sij hawm ncua sij hawm raws li qhov kev thov tshwj xeeb scenario.
2. Bandwidth Range: Cov ntawv thov sib txawv yuav muaj qhov sib txawv bandwidth. Piv txwv li, cov tshuab kev sib txuas lus feem ntau xav tau qhov dav bandwidth, thaum qee lub tshuab radar tsuas yog xav tau cov teeb liab nyob rau hauv ib qho tshwj xeeb zaus. Tsis tas li ntawd, nws yog ib qho tsim nyog los xav txog qhov sib txawv bandwidth yam ntxwv ntawm ib hom fiber ntau thiab ntau hom fiber ntau hom. Ib hom fiber ntau yog tsim rau kev siv ntev-ntev thiab siab bandwidth, thaum multimode fiber yog tsim rau kev siv luv luv.
3 Cov kev cai poob: Txiav txim siab qhov siab tshaj plaws tso cai poob raws li daim ntawv thov yuav tsum tau ua. Nyob rau hauv cov ntaub ntawv siv tau, tsis tshua muaj optical fibers thiab zoo connectors yuav raug xaiv los txo cov teeb liab attenuation.
4 Ib puag ncig tej yam kev mob: Qee daim ntawv thov yuav xav tau kev ua haujlwm ntawm qhov kub thiab txias, yog li xaiv cov fibers kho qhov muag uas tuaj yeem ua haujlwm ib txwm nyob hauv qhov ntsuas kub. Tsis tas li ntawd, nyob rau hauv qee qhov chaw, cov fibers optical yuav tsum muaj qee yam kev siv zog los tiv thaiv kev puas tsuaj.
5. Tus nqi siv nyiaj: Xaiv cov nqi kho qhov muag ncua sij hawm raws li cov peev nyiaj. Kev ua haujlwm siab fiber ntau ncua kab yuav kim, tab sis lawv tsim nyog rau qee yam kev siv tseem ceeb.
6 Cov xwm txheej tshwj xeeb ntawm daim ntawv thov: nkag siab txog cov kev cai tshwj xeeb ntawm cov ntawv thov tshwj xeeb, xws li seb puas yuav tsum tau hloov qeeb, txawm tias muaj lwm yam haujlwm (xws li amplifiers, lim, thiab lwm yam) yuav tsum tau ua ke. Nyob rau hauv luv luv, zoo xaiv qhov tsim nyog fiber optic ncua kab yuav tsum muaj kev xav txog ntau yam. Peb cia siab tias cov kauj ruam saum toj no thiab yam tseem ceeb tuaj yeem pab koj xaiv qhov tsim nyog optic ncua kab ODL.
