Yuav ua li cas yuav optical fais fab meter, lub teeb qhov chaw, optical multimeter?
Optical wavelength: Tam sim no, qhov muag wavelength siv hauv kev sib txuas lus yog ob yam: 1310nm thiab 1550nm.
Lub hwj chim kho qhov muag: lub xov tooj tam sim no, Unicom, mobile, Tietong, Netcom department los ntsuam xyuas lub zog ntau yam -70dbm ~ +3dbm tuaj yeem ua tau raws li qhov yuav tsum tau ua; xov tooj cua thiab TV department (cov tuam txhab yees duab) qee zaum sim lub zog ntawm qhov loj dua, yuav tsum yog -55dbm ~ +20dbm lub zog ntsuas ntau yam
Lub teeb qhov chaw: kev sib txuas lus sector daim ntaub ntawv yog 1310nm thiab 1550nm wavelength, ces tus coj instrumentation yuav tsum yog 1310nm thiab 1550nm lub teeb qhov chaw ntawm ob yam.
Lub teeb liab qhov chaw: tam sim no feem ntau siv yog 650nm liab teeb qhov chaw. Hauv kev tsim kho engineering thiab kev saib xyuas feem ntau ntawm cov neeg ua haujlwm los ntawm cov neeg nyiam. Muaj peev xwm ua kom pom tseeb hauv cov khoom siv kho qhov muag ntawm cov fiber ntau, kev txiav txim siab yooj yim ntawm pigtail los ntawm thiab dhau los, yog qhov muaj zog ntxiv rau OTDR, qhov project tau siv dav, thiab ntau dua li cov sij hawm siv lub ntsuas hluav taws xob kho qhov muag. . Nws raug nquahu kom yuav lub ntsuas hluav taws xob kho qhov muag lossis kho qhov muag multimeter nrog lub teeb liab, uas tuaj yeem pab tau zoo heev rau kev siv engineering.
Lub teeb qhov hluav taws xob tso zis hluav taws xob: lub zog tso zis yog hais txog lub teeb pom kev ruaj khov nyob rau hauv hom kev ua haujlwm thiab tom qab preheating ruaj khov ua haujlwm tso zis hluav taws xob kho qhov muag. Muaj ob hom LED thiab LD. LED belongs rau lub teeb-emitting diode generated thaum lub tso zis hwj chim yog heev me me lub teeb qhov chaw, feem ntau yog cov zis tsawg dua los yog sib npaug rau -10dbm; LD belongs rau lub tshuab hluav taws xob laser, feem ntau nrog lub teeb pom kev zoo dua lossis sib npaug ntawm -10dbm, lub teeb pom kev zoo ntawm lub teeb hluav taws xob yuav tuaj yeem ua kom yooj yim rau kev sim ntsuas qhov ntev ntawm lub teeb pom kev zoo ntawm lub teeb pom kev noj qab haus huv.
Lub teeb ci ruaj khov: lub teeb ci ruaj khov nyob rau hauv qhov kev ua haujlwm tau teev tseg thiab tom qab ua haujlwm ruaj khov, txij lub sijhawm T{{0}} mus rau lub sijhawm T1 qhov kev hloov pauv ntawm qhov tso zis hluav taws xob kho qhov muag yog lub npe hu ua kev ruaj ntseg ntawm cov lub zog ntawm lub teeb ruaj khov. Lub teb chaws tus qauv: Tsawg dua lossis sib npaug rau 0.1db (15min) Tsawg dua lossis sib npaug rau 0.5db (5min)
Optical multimeter: qhov kev ua haujlwm tam sim no muaj zog dua, thiab txawm hais tias hauv engineering lossis kev saib xyuas txhua hnub lossis kev qhia, multimeter yog qhov kev xaiv zoo, tshwj xeeb tshaj yog tsim nyog rau kev sib txuas lus ntawm kev ntsuas qhov muag fiber ntau thiab lwm yam. Cov khoom siv kuaj no muab cov high-precision hlau ferrule calibrated optical thaj qaum, ruaj khov shockproof nqa cov ntaub ntawv thiab tu pas nrig tshwj xeeb uas tsim los rau tu kho qhov muag interfaces. Lub ** embodiment ntawm cov neeg siv khoom xav tau, tab sis kuj yog koj txoj kev xaiv ntse!
Optical attenuation tus nqi: Cov chaw sib txuas lus feem ntau yuav tsum tau kuaj qhov kho qhov muag attenuation tus nqi ntawm ib feem ntawm optical fiber, piv txwv li qhov txo qis ntawm lub hwj chim kho qhov muag tom qab lub teeb ci dhau los ntawm qhov muag fiber ntau. Yuav tsum tau siv cov cuab yeej yog: lub teeb ci, lub ntsuas hluav taws xob kho qhov muag
