Hauv kev sib txuas lus optical fiber ntau, hom yooj yim tshaj plaws yog: optical transceiver-fiber-optical transceiver, yog li lub cev tseem ceeb uas cuam tshuam rau kev sib kis deb yog optical transceiver thiab optical fiber.Muaj plaub yam uas txiav txim siab qhov kev sib kis ntawm qhov muag fiber ntau, uas yog lub zog kho qhov muag, kev tawg, kev poob, thiab kev nkag siab ntawm tus neeg txais.Optical fiber tuaj yeem siv tsis tau tsuas yog xa cov cim analog thiab cov cim digital, tab sis kuj ua tau raws li cov kev xav tau ntawm kev xa cov video.
Optical zog
Qhov ntau dua lub zog txuas rau hauv fiber ntau, qhov sib kis tau ntev dua.
Dispersion
Hais txog chromatic dispersion, qhov loj ntawm chromatic dispersion, qhov loj dua qhov waveform distortion yuav yog.Raws li qhov sib kis tau ntev dua, lub waveform distortion ua hnyav dua.Hauv kev sib txuas lus digital, waveform distortion yuav ua rau muaj kev cuam tshuam cov cim, txo qhov rhiab heev ntawm lub teeb tau txais, thiab cuam tshuam rau qhov kev ncua deb ntawm lub system.
Poob
Xws li fiber ntau optic connector poob thiab splicing poob, feem ntau poob ib kilometer.Qhov tsawg dua qhov poob ib mais, qhov tsawg dua qhov poob thiab qhov ntev ntawm qhov kev sib kis.
Tus neeg txais kev xav
Qhov siab dua qhov rhiab heev, qhov me dua qhov tau txais lub zog kho qhov muag thiab qhov ntev ntev.
