Chiyambi chamzere wochedwa fiber optic

Mzere wochedwa fiber optic ndi chipangizo chomwe chimachedwetsa ma siginecha pogwiritsa ntchito mfundo yoti ma siginecha owoneka amafalikira mu ulusi wamaso. Zimapangidwa ndi zinthu zoyambira monga ma optical fibers,EO modulatorsndi olamulira. Optical fiber, ngati njira yotumizira, imatumiza ma siginecha powonetsa kapena kubweza ma sign amkati pakhoma lamkati, potero kukwaniritsa kuchedwa.

Mu mzere wa kuchedwa kwa fiber optic, zizindikiro zazikulu zaumisiri za gawo lolowetsamo zimaphatikizanso kukula kwa siginecha, mawonekedwe osinthika, ma frequency ogwiritsira ntchito, bandwidth, matalikidwe, gawo, ndi chiwongolero choyimirira. Zizindikiro zazikulu zaumisiri za gawo lotulutsa zikuphatikiza kuchuluka kwa magwiridwe antchito, nthawi yochedwa, kulondola, chithunzi chaphokoso, kutayika, chiwongolero chamagetsi oyimilira, komanso kusasinthika kwa gawo la amplitude. Kuonjezera apo, pali zizindikiro zakunja, monga kutentha kwa ntchito, chinyezi, zizindikiro zitatu, kutentha kwa yosungirako, mawonekedwe a mawonekedwe, mawonekedwe a magetsi, ndi zina zotero.

Zizindikiro zazikulu zaumisiri

1. Mafupipafupi ogwiritsira ntchito: Ikhoza kuphimba magulu a P/L/S/C/X/K.

2. Kutayika kwa Flux: Chiŵerengero cha mphamvu ya siginecha yolowera ku mphamvu yotulutsa mphamvu. Zotayika izi zimachepetsedwa kwambiri ndi kuchuluka kwa mphamvu ya laser ndiPhotodetector.

3. Kuchedwa nthawi: Nthawi yochedwa imatsimikiziridwa makamaka ndi kutalika kwa fiber optical.

4. Dynamic range: Ndi chiŵerengero cha siginecha yayikulu yotulutsa mpaka chizindikiro chocheperako. Mphamvu yayikulu ya chizindikiro P imakhala yocheperako chifukwa cha kuchuluka kwamphamvu kwa laser (yogwirizana ndi 80% matalikidwe amtundu wa kuchuluka kwa machulukitsidwe) ndi mphamvu yochulukirapo ya laser.

5. Kuponderezedwa kwa Harmonic: Choyambitsa chachikulu cha mbadwo wa harmonic ndi chifukwa cha katundu wosagwirizana. Pamene panopa ikuyenda mu katundu ndipo alibe mgwirizano liniya ndi voteji ntchito, sanali sinusoidal panopa amapangidwa, potero kupanga harmonics. Kuwonongeka kwa Harmonic kumabweretsa chiwopsezo chachikulu ku machitidwe amagetsi. Kutenga njira zofananira kupondereza ndikuchepetsa kuvulaza kwake kumadziwika kuti kukakamiza kwa harmonic.

Zochitika zogwiritsira ntchito mzere wochedwa fiber optic: Radar systems; Dongosolo lapakompyuta la Optical Kuyesa kwamagetsi Njira yolumikizirana ndi zingwe zolumikizira ma Signal encoding ndi caching. Fiber optic delay line ndi ukadaulo womwe umagwiritsa ntchito ma optical fiber kutumiza ma siginecha ndikuchedwetsa ma sign kudzera pazida zamagetsi. M'madera amakono oyankhulana ndi kuyesa, magetsimizere yochedwa ya optical fiberamagwiritsidwa ntchito kwambiri ndipo amagwira ntchito yofunika kwambiri pazinthu zambiri zofunika.
