Kho qhov muag Attenuator thiab kho qhov muag fais fab 'meter' Calibration
Hauv cov kab ke hauv xov tooj cua fiber ntau, qhov no yog qhov tseeb tias qib fais fab ntawm lub teeb liab kho qhov muag, tsis hais hauv qhov chaw pub dawb lossis hluav taws xob hauv xov hluav taws xob tsis zoo li qub. Piv txwv, rau cov txais xov fiber ntau, lub teeb ntau dhau tuaj yeem dhau nws thiab thuam qhov yuam kev tsis raug. Yuav kom ua tiav qhov zoo tshaj plaws kev ua yuam kev sib piv, lub teeb hluav taws xob yuav tsum raug txo kom tsawg, lub sijhawm no yuav tsum tau kho qhov muag pom kom sib npaug ntawm lub zog ntawm lub teeb los ntawm kev txo lub zog ntau dua thiab ua kom haum rau cov nplaim hluav taws xob kis ntawm cov khoom sib txawv.
Txoj haujlwm ua haujlwm ntawm cov fiber ntau thev naus laus zis tuaj yeem piv nrog daim looj tsom iav, uas nqus lub zog ntxiv lub teeb thiab tiv thaiv koj lub qhov muag kom tsis pom kev. Attenuators feem ntau muaj qhov ua haujlwm wavelength (feem ntau los ntawm 1310 txog 1550nm) nyob rau hauv uas lawv nqus lub teeb zog sib npaug. Qhov tseem ceeb ntawm tus yam ntxwv zoo fiber ntau yog tias lawv yuav tsum tsis txhob saib lub teeb hloov, lawv yuav tsum nqus lub teeb ntxiv tsis muaj kev puas tsuaj. Txij li thaum lub teeb hluav taws xob siv nyob rau hauv kev sib txuas lus fiber ntau muaj qhov qis qis, lawv feem ntau tuaj yeem nqus tau yam tsis muaj kev ceeb toom rau kev puas tsuaj rau nws tus kheej.
Fiber optic attenuators yog siv rau kev txo lub zog ntawm lub teeb nyob rau hauv fiber optic network. ob hom fiber ntau optic attenuators, tsau nqi fiber ntau optic attenuator xa mus rau attenuator uas tuaj yeem txo lub zog ntawm fiber ntau lub teeb ntawm ib qho teeb meem poob, piv txwv li, 2dB. Lawv cov ntawv thov suav nrog kev sib txuas xov tooj sib txuas, chaw ntsuas fiber ntau, LAN thiab CATV cov tshuab. Tsau muaj nuj nqi fiber optic attenuators yog tsim los ntawm plaub pawg: Tsau-Plug hauv hom, hom kho kom haum Lub xov tooj attenuator, hom nthab hom attenuator, thiab hom hle Hybrid Adapter hom. Thaum kho qhov fiber ntau optic attenuator xa mus rau attenuator uas tuaj yeem tsim kom muaj qhov kho qhov muag tsis haum rau cov kab txuas hluav taws xob, lawv tau siv dav dav rau ntsuas thiab ntsuas, tab sis lawv kuj muaj kev siv dav hauv EDFA rau kev sib luag lub teeb hluav taws xob ntawm cov sib txawv. Kuj tsis paub meej Fiber optic attenuators yog tsim los ntawm peb pawg: Variable plug-in type, Variable adapter type, Variable In-line type thiab Manual VOA hom.
Tus attenuators tuaj yeem yog poj niam mus rau poj niam uas yog hu ua bulkhead fiber optic attenuator lossis txiv neej rau poj niam uas tseem hu ua ntsaws fiber ntau optic attenuator. Bulkhead thiab plug hom yog tsim los tsis muaj cov cab cuam; lwm hom inline fiber optic attenuator yog tsim nrog ib daim ntawm fiber ntau optic cable.Wide ntau yam sib txawv & inline fiber optic attenuators. Cov kab inline fiber optic attenuators yog nrog ntau dua attenuation piv nrog tsoos txuas hom fiber ntau optic attenuators. Kuj tsis paub meej nyob rau hauv-kab Optical attenuators feem ntau siv nrog cov ntsuas hluav taws xob nyob hauv cov tshuab hluav taws xob hauv cov tshuab ua kom sib npaug kom sib npaug qhov nce thoob cov sib txawv kev khiav hauj lwm wavelengths.
Ntau hom fiber ntau rau cov ua yeeb yaj kiab tau muab los ntawm FOCC uas suav nrog LC, SC, thiab ST, FC, MU, E2000, Tsau Adapter Hom Attenuators, Tsau Rau Kab Hom Attenuators, Kuj Sib Nqus Attenuator Ntsuas thiab Cov Kab Sib Txawv. Peb cov khoom siv hluav taws xob fiber optic raug tsim tawm raws li cov txheej txheem thoob ntiaj teb thiab suav nrog cov khoom siv fiber ntau hauv lub lag luam tam sim no muaj nyob rau hauv cov khw thoob ntiaj teb.
Tus kws kho qhov muag hluav taws xob yog qhov tseem ceeb uas qhov kev sib txuas lus qib yuav tsum tau kho nyob ntawm ntau lub zog loj. Txhawm rau ua kom ntsuas tau ntseeg tau, ib qho yuav tsum xav txog cov yam ntxwv sib cuam tshuam ntawm fiber ntau qhov muag. Qhov ntsuas qhov muag tau siv nrog qhov ntsuas qhov muag qhov txhab fais fab los ntsuas lub fiber ntau qhov poob, uas tuaj yeem muab ntau hom xws li LED, halogen thiab laser. Nrog rau kev kho qhov muag kom pom tseeb thiab cov hwj huam kho qhov muag hluav taws xob ntsuas lub teeb tsa, kho kom zoo tuaj yeem hloov kho kom yooj yim rau txhua qib yuav tsum tau ua rau telecom thiab CATV network.
