Fiber ntau optic attenuatorsyog cov twj siv uas tau txo qis kho qhov muag pom nyob rau hauv cov hluav taws xob sib txuas los ntawm cov nyiaj tau los yog kho tau. Lawv tuaj yeem tsis tsuas tswj lub zog qib ntawm cov cim kho qhov muag, tab sis kuj tseem siv los kuaj qhov kab thiab qhov muaj zog ntawm cov duab thaij duab thiab cov duab kuaj pom. Fiber optic attenuator muaj ib tug xov tooj ntawm cov sib txawv thiab feem ntau muab faib ua tas li los yog kuj tsis paub meej attenuators. Dab tsi ntxiv, lawv tuaj yeem muab cais ua LC, SC, ST, FC, MU, E 2000 thiab lwm yam. raws li cov sib txawv ntawm cov khoom sib txuas. Kab lus no yuav ua kom luv luv ntawm kev qhia ntawm cov xov hluav taws xob kom pab koj nkag siab zoo.
Vim li cas Peb Xav Tau Fiber Optic Attenuator?
Raws li tau paub rau txhua tus, kho qhov muag fais fab ntawm lub txais khoom thaum kawg txiav txim siab qhov muaj peev xwm ntawm txhua qhov fiber ntau qhov ua xa cov ntaub ntawv. Tab sis nws tsis yog qhov tseeb tias lub teeb liab loj zog tau zoo dua. Qhov tseeb yog tias lub zog tsawg dhau los lossis lub zog ntau dhau yuav ua rau muaj qhov yuam kev siab. Kev siv hluav taws xob ntau dhau lawm tuaj yeem ua rau lub suab nrov amplifier saturates, thaum tsawg dhau los yuav ua rau suab nrov teeb meem vim nws cuam tshuam nrog cov teeb liab.
Feem ntau, lub zog txais hluav taws xob nyob ntawm ob yam tseem ceeb: lub hwj huam pib nkag mus rau hauv lub fiber thiab qhov poob lub hwj chim los ntawm qhov tshwm sim hauv cov kab hluav taws xob fiber ntau cog. Thaum lub zog loj dhau, fiber optic attenuator tuaj yeem pab los ntawm kev txo kom tau txais lub zog rau kev ua haujlwm zoo dua. Feem ntau, multimode systems tsis xav tau kev kho qhov muag vim tias lawv tsis muaj peev xwm tsim tawm hluav taws xob txaus kom txaus siab rau cov khoom txais. Thaum tib hom tshuab, tshwj xeeb tshaj yog rau cov kab txuas luv, xav tau kev xav tau vim tias lawv feem ntau muaj hwj chim ntau dhau. Tab sis tam sim no, qhov nyuaj ntawm kev sib txuas lus xav tau attenuation ob leeg nyob rau hauv tib hom thiab multimode systems.
Kev Ua Hauj Lwm Cov Qauv ntawm Fiber Optic Attenuator
Muaj ntau txoj hauv kev ntawm lub zog attenuation, nrog rau kev nqus, xav txog, diffusion, tawg, deflection, diffraction, thiab dispersion, thiab lwm yam. Optical attenuators feem ntau ua haujlwm los ntawm kev nqus lub teeb, zoo li nruab nrab ntuag nyias zaj duab xis lim. Lossis lawv ua haujlwm los ntawm qhov teeb pom kev zoo xws li cov ntxiab cua. Lwm hom kev tuav pov hwm kev siv qhov ntev ntawm qhov siab-poob kho qhov muag fiber ntau, uas ua haujlwm raws li nws cov tswv yim hluav taws xob teeb liab fais fab qib nyob rau hauv txoj kev uas nws cov paib hluav taws xob teeb hluav taws xob theem qis dua qhov kev tawm tswv yim.
Taag Fiber Optic Attenuators VS Sab Nraud Kho Qhov Muag Kho Kom Sib Tw
Fiber optic attenuators muaj peev xwm raug faib ua ob yam: tsau kho kom zoo nkauj attenuator thiab attenuator nce mus nce los. Neb ob leeg puav leej muaj cov yam ntxwv zoo sib xws.
Tsau kho qhov muag tawm ntawm lub ntsej muag yog cov qauv kho kom nruj uas tuaj yeem txo cov cim taw qhia los ntawm tus nqi tshwj xeeb. Raws li cov teeb liab txuas mus rau ib qho cuab yeej lossis node hauv kev sib txuas lus sib txuas, lub zog tau raug txo kom txog qib uas tsim nyog rau nws daim ntawv thov. Lawv tuaj yeem ua cov cim kev cuam tshuam tsawg dua ntawm qhov teeb meem thiab yog li ua rau cov ntaub ntawv kho kom raug tseeb dua. Tsau attenuators muaj nyob nrog ib hom, multimode thiab polarization tswj fiber ntau. Thiab lawv zoo tagnrho rau attenuating ib hom fiber ntau kab sib txuas hauv ntau daim ntawv thov, xws li LAN (Local Area Network), CATV (Zej Zog Nkag Xov Tooj) thiab xov tooj sib txuas.
Kuj tsis paub meej fiber optic attenuators muaj rugged, cov khoom siv tes uas siv los ntsuas thiab ntsuas, lossis sib txig sib luag ntawm lub zog ntawm cov cim sib txawv. Lawv tuaj yeem muab ntau qhov kom muaj nuj nqis nrog kev hloov kho kom haum. Vim hais tias cov attenuators kuj tsis paub meej ua hauj lwm los ntawm thaiv cov nqaj hlau ncaj qha, lawv polarization insensitive. Zoo li cov paj hluav taws xob sib txawv, cov paj hluav taws xob kho kom zoo nkauj kuj tseem muaj nrog ib hom, multimode, los yog kev tswj tuav tswj.

Fiber ntau attenuatorsyog cov hauv paus tseem ceeb hauv kev siv xov tooj sib txuas lus. Lawv tuaj yeem hloov kho cov teeb liab theem kom nce kev sib txuam hauv network thiab muab kev tswj hwm ntawm lub zog kho qhov muag. Dhau li ntawm fiber ntau kho qhov muag atternuators thiab attenuators kuj tsis paub meej, muaj ntau ntau lwm hom atternuators, xws li loopback attenuators, built-in attenuators kuj sib txawv thiab lwm yam.
