Yuav ua li cas yuav ib lub tshuab hluav taws xob kho qhov muag, lub teeb qhov chaw, thiab qhov muag pom kev multimeter?
Optical wavelength: Tam sim no, muaj ob hom optical wavelengths siv hauv kev sib txuas lus: 1310nm thiab 1550nm
Lub hwj chim kho qhov muag: Tam sim no, lub zog hluav taws xob tau sim los ntawm kev sib txuas lus, Tuam Tshoj Unicom, Tuam Tshoj Mobile, Tuam Tshoj Tietong, thiab Tuam Tshoj Netcom departments yog -70dbm~+3dbm, uas ua tau raws li qhov yuav tsum tau ua; Lub chaw tshaj tawm xov xwm thiab TV (Shitong Company) qee zaum kuaj lub zog siab, yuav tsum tau ntsuas lub zog ntawm -55dbm rau +20dbm
Lub teeb qhov chaw: Lub wavelengths siv los ntawm lub tuam tsev kev sib txuas lus yog 1310nm thiab 1550nm, yog li cov cuab yeej siv lub teeb siv yuav tsum yog 1310nm thiab 1550nm.
Lub teeb liab: Tam sim no, feem ntau siv lub teeb liab yog 650nm. Txaus siab rau cov neeg ua haujlwm hauv kev tsim kho engineering thiab kev saib xyuas. Nws tuaj yeem pom qhov pom kev tsis sib haum xeeb ntawm cov fibers kho qhov muag thiab yooj yim txiav txim siab rau / tawm ntawm tus Tsov tus tw fibers, uas yog lub zog ntxiv rau OTDR. Nws yog dav siv nyob rau hauv engineering thiab txawm ntau zaus tshaj optical fais fab tuag meters. Nws raug nquahu kom yuav lub ntsuas hluav taws xob kho qhov muag lossis multimeter nrog lub teeb liab, uas tuaj yeem pab txhawb kev siv engineering.
Lub teeb qhov hluav taws xob tso zis hluav taws xob: Cov zis hluav taws xob yog hais txog qhov tso zis hluav taws xob kho qhov muag ntawm lub teeb pom kev ruaj khov tom qab preheated thiab stabilized nyob rau hauv ib qho kev khiav hauj lwm hom. Muaj ob hom: LED thiab LD. LED belongs rau lub teeb pom kev zoo nrog lub zog tso zis tsawg heev thaum tsim lub teeb-emitting diodes, thiab cov zis ntau dua yog tsawg dua lossis sib npaug rau -10dbm; LD belongs rau lub laser tiam qhov chaw, feem ntau yog siv lub teeb qhov loj dua los yog sib npaug rau -10dbm. Nrog lub zog tso zis siab ntawm lub teeb ci, nws yog qhov yooj yim los ntsuas qhov ntsuas qhov ntsuas qhov ntsuas ntawm qhov ntev-ntev fibers.
Lub teeb ci ruaj khov: Lub zog ruaj khov ntawm lub teeb ruaj khov yog hais txog qib ntawm kev hloov pauv ntawm lub teeb tso zis hluav taws xob los ntawm lub sijhawm T{{0}} mus rau lub sijhawm T1 tom qab kev ua haujlwm ruaj khov ntawm qhov chaw teeb pom kev ruaj khov hauv qhov teev tseg ua hauj lwm hom thiab preheating. 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: Tam sim no, nws muaj lub zog muaj zog thiab yog qhov kev xaiv zoo rau engineering, kev saib xyuas txhua hnub, lossis kev qhia. Nws yog tshwj xeeb tshaj yog haum rau kev ntsuas fiber ntau hauv kev sib txuas lus. Cov pob ntawv xeem muab cov khoom siv hlau ntsaws calibration optical jumpers, cov ntaub ntawv muaj zog-absorbing, thiab cov pas nrig ntxuav tshwj xeeb tsim los ntxuav cov khoom siv kho qhov muag. Qhov tshwm sim ntawm cov neeg siv khoom xav tau kev pab kuj yog koj qhov 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 cov khoom siv kho qhov muag, uas yog qhov txo qis ntawm lub zog kho qhov muag ntawm lub teeb pom kev tom qab dhau los ntawm fiber ntau optical. Cov cuab yeej xav tau yog: lub teeb ci, lub ntsuas hluav taws xob kho qhov muag
Los ntawm cov lus qhia saum toj no, nrog rau kev nkag siab ntawm ntau yam ntsuas thiab qhov ntsuas qhov ntsuas qhov muag, ib tus tuaj yeem xaiv rau lawv tus kheej lub ntsuas hluav taws xob kho qhov muag, lub teeb pom kev zoo, thiab kho qhov muag multimeter.
