FC Tsau Fiber Optic Attenuator (Singlemode, Txiv neej rau Poj Niam, APC, 1 ~ 25dB)
Fiber optic attenuators yog cov cuab yeej siv los txo cov hluav taws xob kho qhov muag los ntawm qee qib hauv fiber ntau optic network. Fiber Attenuators feem ntau yog siv thaum lub teeb liab tuaj txog ntawm lub receiver muaj zog heev thiab li no yuav overpower cov khoom tau txais. Qhov no tuaj yeem tshwm sim vim qhov tsis sib haum xeeb ntawm cov khoom xa tawm / txais (transceivers, media converters), lossis vim tias cov khoom hloov pauv tau tsim los rau kev ncua ntev dua li qhov uas lawv tau siv. Qee lub sij hawm attenuators kuj tau siv rau kev ntxhov siab kuaj lub network txuas los ntawm kev txo cov teeb liab lub zog (nce dB attenuation) kom txog rau thaum qhov kev sib txuas kho qhov muag tsis ua tiav, yog li txiav txim siab lub teeb liab qhov kev nyab xeeb uas twb muaj lawm.
Qhov no FC APC fiber ntau attenuator muaj doped fiber ntau haum rau ob qho tib si 1310nm thiab 1550nm ua haujlwm. Tsau attenuation qhov tseem ceeb muaj nyob rau hauv 1dB increments ntawm 1 txog 25dB. Peb muaj cov txheej txheem tsim khoom ntawm attenuator, thiab tuaj yeem ua tau raws li cov neeg siv khoom xav tau. Txhua lub attenuator raug xa mus nrog cov ntawv xeem uas ua rau nws yooj yim rau cov neeg siv khoom los xyuas qhov kev ua haujlwm kho qhov muag sai.

Dab tsi yog fiber ntau attenuator thiab thaum twg kuv xav tau nws?
Lub teeb mus ncig ntawm cov khoom siv kho qhov muag fiber ntau yog lub luag haujlwm tseem ceeb ntawm cov ntaub ntawv lossis cov ntaub ntawv uas yuav tsum tau xa mus raws cov fiber ntau optical cable. Txhawm rau kom tau txais cov ntaub ntawv muaj txiaj ntsig yam tsis muaj qhov yuam kev, lub kaw lus yuav tsum tau txais lub teeb ntawm qhov pom kev pom qhov txo qis. Txawm tias tsawg los yog ntau dhau lub zog yuav ua rau muaj qhov yuam kev me ntsis. Qhov Me ntsis yuam kev Rate (tseem BER) yog tus lej ntawm qhov yuam kev me me rau ib lub sijhawm. Qhov kev ua yuam kev me ntsis yog tus lej ntawm qhov yuam kev me me muab faib los ntawm tag nrho cov lej ntawm cov khoom hloov pauv thaum lub sijhawm kawm. Qhov kev ua yuam kev me ntsis yog qhov ntsuas tsis ua haujlwm, feem ntau qhia raws li feem pua. Lub zog ntau dhau, thiab lub receiver amplifier saturates, tsawg dhau thiab suab nrov dhau los ua teeb meem vim nws cuam tshuam nrog lub teeb liab. Lub hwj chim txais no nyob ntawm ob yam tseem ceeb: ntau npaum li cas lub hwj chim tau tso rau hauv fiber ntau los ntawm lub transmitter thiab ntau npaum li cas poob los ntawm attenuation nyob rau hauv optical fiber cable cog uas txuas lub transmitter thiab receiver.
ATTENUATORS ua haujlwm PRINCIPLE
Yog tias lub zog siab dhau lawm vim nws feem ntau nyob rau hauv luv luv ib hom tshuab nrog laser transmitters, koj tuaj yeem txo tus txais lub zog nrog lub attenuator. Kev txo hwj chim yog ua los ntawm xws li kev nqus, kev xav, diffusion, tawg, deflection, diffraction, thiab dispersion, thiab lwm yam. Optical attenuators feem ntau ua hauj lwm los ntawm absorbing lub teeb, xws li looj tsom iav dub nqus lub zog ntxiv. Lawv feem ntau muaj qhov ua haujlwm wavelength ntau yam uas lawv nqus tag nrho lub teeb lub zog sib npaug. Lawv yuav tsum tsis txhob cuam tshuam lub teeb lossis tawg lub teeb nyob rau hauv qhov sib txawv ntawm huab cua, vim qhov ntawd tuaj yeem ua rau tsis xav rov qab xav txog hauv fiber ntau. Lub attenuating fiber ntau yog tsim los ntawm kev siv cov tshuaj doping cov txheej txheem los qhia txog kev hloov pauv lossis tsis tshua muaj lub ntiaj teb cov ntsiab lus rau hauv cov tub ntxhais fiber ntau. Cov dopant txo qhov kis ntawm fiber ntau. Lub degree ntawm attenuation nyob ntawm seb cov khoom siv li dopant, qib dopant, thiab qhov ntev ntawm qhov attenuation ntu.
