Kev Taw Qhia Txog Kab Ntsig Fiber Optic Delay

Kev Taw Qhia raufiber optic qeeb kab

Cov kab fiber optic qeeb yog ib lub cuab yeej uas qeeb cov teeb liab los ntawm kev siv lub hauv paus ntsiab lus uas cov teeb liab optical kis mus rau hauv cov fibers optical. Nws yog tsim los ntawm cov qauv yooj yim xws li cov fibers optical,Cov EO modulatorsthiab cov tswj. Optical fiber, ua ib qho chaw xa xov, xa cov teeb liab los ntawm kev cuam tshuam lossis refracting optical teeb liab ntawm phab ntsa sab hauv, yog li ua tiav lub teeb liab qeeb.

Hauv cov kab fiber optic qeeb, cov cim qhia tseem ceeb ntawm qhov nkag muaj xws li qhov loj ntawm lub teeb liab nkag, qhov ntau thiab tsawg, zaus ua haujlwm, bandwidth, amplitude, theem, thiab piv nthwv dej ntawm qhov nkag. Cov cim qhia tseem ceeb ntawm qhov tso zis muaj xws li zaus ua haujlwm, lub sijhawm qeeb, qhov tseeb, tus lej suab nrov, poob, qhov sib piv nthwv dej ntawm qhov hluav taws xob, thiab qhov sib xws ntawm qhov siab thiab theem. Tsis tas li ntawd, muaj qee cov cim qhia sab nraud, xws li qhov kub ua haujlwm, av noo, cov yam ntxwv peb-pov thawj, qhov kub cia, daim ntawv sib txuas, daim ntawv muab hluav taws xob, thiab lwm yam.

Cov cim qhia tseem ceeb

1. Kev ua haujlwm zaus: Nws tuaj yeem npog cov P/L/S/C/X/K bands.

2. Kev poob ntawm cov kua dej: Qhov sib piv ntawm lub zog ntawm lub teeb liab nkag mus rau lub zog ntawm lub teeb liab tso zis. Cov kev poob no feem ntau yog txwv los ntawm cov teebmeem quantum ntawm lub laser thiablub tshuab ntes duab.

3. Lub sijhawm ncuaLub sijhawm qeeb yog feem ntau txiav txim siab los ntawm qhov ntev ntawm cov khoom siv fiber ntau.

4. Dynamic range: Nws yog qhov piv ntawm qhov siab tshaj plaws tso zis teeb liab rau qhov tsawg kawg nkaus tso zis teeb liab. Lub zog siab tshaj plaws ntawm lub teeb liab P yog txwv los ntawm qhov siab tshaj plaws nkag mus rau lub laser (sib raug rau 80% amplitude modulation ntawm qhov ntau ntawm saturation) thiab lub zog overload ntawm lub laser.

5. Kev Tswj Xyuas Harmonic: Qhov ua rau muaj kev tsim harmonic yog vim muaj cov khoom thauj tsis sib xws. Thaum tam sim no ntws los ntawm ib qho khoom thauj thiab tsis muaj kev sib raug zoo nrog lub zog hluav taws xob, tam sim no tsis yog sinusoidal raug tsim, yog li tsim cov harmonics. Kev ua qias tuaj ntawm harmonic ua rau muaj kev hem thawj loj rau cov kab ke fais fab. Kev siv cov kev ntsuas kom txo qis thiab txo nws qhov kev puas tsuaj hu ua kev tswj xyuas harmonic.

Cov xwm txheej siv ntawm cov kab fiber optic qeeb: Radar systems; Optical computer system Electronic countermeasure Optical fiber communication system Signal encoding thiab caching. Fiber optic qeeb kab yog ib qho thev naus laus zis uas siv cov fiber optic los xa cov teeb liab thiab qeeb cov teeb liab los ntawm cov khoom siv hluav taws xob. Hauv kev sib txuas lus niaj hnub thiab kev sim teb, hluav taws xobcov kab fiber ntau qeebsiv dav thiab ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw tseem ceeb.
