Kev Qhia Rau Fiber Optic Attenuator
Fiber Attenuators yog cov khoom siv los txo cov kev ua haujlwm fiber ntau ntawm ib qib los ntawm qhov kev txiav txim siab ua ntej. Qhov sib zog ntawm lub teeb liab tau piav qhia hauv kev txiav txim siab (dB) dhau qhov kev ncua deb ntawm lub teeb liab mus. Attenuator muab qee qhov sib cais ntawm cov twj paj nruag, yog li txo kev ntsuas kev sib cuam tshuam. Qhov no tuaj yeem ua tiav los ntawm attenuating lub teeb liab tsis cuam tshuam vim kev sib piv tsis zoo. Fiber optic attenuators siv nyob rau hauv cov ntawv thov qhov twg lub teeb liab kho qhov muag muaj zog heev thiab yuav tsum tau txo qis, nws yog siv rau fiber ntau qhov ntsuas ntawm kev ntsuas, cim teeb meem rau kev sib txuas lus luv thiab kev ntsuas qhov system, thiab piv txwv, hauv ntau -wavelength fiber optic system, koj yuav tsum sib npaug ntawm cov channel kho qhov muag muaj zog kom txhua txoj kev sib tshooj muaj qib sib xws. Qhov no txhais tau tias kom txo cov zog sib zog 'zog ua kom sib zog raws cov hluav taws xob qis.
Cov theem pib hom ntawm optical attenuators yog tsau thiab Variable Optical Attenuators. Cov hom siv feem ntau yog poj niam mus rau txiv neej ntsaws hom fiber ntau optic attenuator, nws muaj cov khoom siv fiber ntau ntawm ib sab thiab lwm sab yog poj niam hom fiber ntau kho qhov muag. Poj niam mus rau txiv neej cov neeg kho tshuab attenuator yog sib dhos nrog cov sib txuas hom txuas, yog li nws tuaj yeem txuas nrog ib thaj xwb, xws li LC Attenuator, sc Attenuator, fc Attenuator, st Attenuator, thiab lwm yam.
Taag Attenuators
Cov khoom siv tas li tsim nyog muaj qhov hloov pauv uas tau hais meej hauv qhov decibels. Tsuas yog nws lub npe cuam tshuam, cov nqi tsis txawv tus nqi attenuator tus nqi tsis tuaj yeem sib txawv tau. Tus attenuation yog qhia hauv dB. Kev khiav hauj lwm wavelength rau optic attenuators yuav tsum tau hais kom meej rau cov ranten attenuation, vim hais tias optic attenuation ntawm cov khoom sib txawv nrog wavelength. Lawv cov ntawv thov muaj kev sib txuas xov tooj sib txuas, chaw sib tw fiber ntau, Chaw Hauv Cheeb Tsam Network (Lan) thiab Catv systems.
Tsau tus nqi attenuators yog tsim ntawm ob pawg loj: Hauv hom kab thiab txuas hom. Cov kab hom zoo li lub tiaj fiber ntau them cable; nws muaj cov kab xaim hluav taws xob kaw nrog ob lub txuas uas koj tuaj yeem hais hom. Cov kab hauv fiber ntau optic attenuator haum rau siv nrog kho qhov muag kab hluav taws xob. Txhawm rau siv cov kab hauv Fiber Optics Attenuators cia li xaiv hom txuas koj xav tau ST, SC, LC, & FC Muaj, cov lus Polish (PC, UPC lossis APC angled Polish) & Decibel dB kev ntsuas.
Kuj tsis Paub meej Attenuators
Kuj tsis paub meej attenuators tuaj nrog ntau yam sib txawv tsim. Lawv ib txwm siv rau kev ntsuas thiab ntsuas, tab sis lawv kuj muaj kev siv dav dav hauv Edfas rau kev sib txig sib luag lub zog ntawm cov kem sib cais. Ib hom hloov pauv tau coj los ua rau D-puab fiber ntau ua hom evanescent teb ntaus. Yog tias ib qho loj ntawm cov khoom siv sab nraud, uas nws qhov ntsuas refractive yog qhov ntau dua li qhov ntsuas tau zoo siv, hloov qee qhov ntawm thaj teb evanescent rov qab nkag mus rau sab nrauv, hom yuav tuaj yeem ua xau thiab qee qhov hluav taws xob optic tuaj yeem tawg. Yog tias qhov ntsuas tawm ntawm cov khoom siv sab nraud tuaj yeem hloov nrog lub ntsiab lus tswj tau, ncaj qha los ntawm cov teebmeem xws li thermo-optic, electro-optic, lossis acoustic-optic, cov khoom siv nrog cov tswj tau kom ua tiav tau. Lwm hom kev hloov pauv muaj xws li muaj qhov sib txawv ntawm huab cua, qhov tseem ceeb, 3 kauj ruam thiab ntau dua.
Raws li nws los txog kom tau txais lub fiber optic attenuator koj muaj ntau txoj kev xaiv tau teev saum toj no, yog li ua ntej koj yuav ib qho koj yuav tsum paub tseeb ntawm qib dab tsi koj xav attenuate koj lub teeb liab thiab tom qab ntawd xaiv hom twg yuav ua haujlwm zoo tshaj rau koj. Kev siv lub sijhawm los xaiv qhov tsim nyog tuaj yeem txuag koj lub sijhawm loj.
