Tus OTDR ntsuas qhov deb thiab poob ntawm ob lub cim. Qhov no tuaj yeem siv los ntsuas qhov poob ntawm qhov ntev ntawm fiber ntau, qhov twg OTDR yuav xam qhov sib npaug ntawm cov fiber ntau, lossis poob ntawm qhov sib txuas lossis sib txuas.
Kuv yuav nyeem daim ntawv qhia OTDR li cas?
Ua ntej tso ib qho ntawm cov cim lossis tus cursors (feem ntau hu ua 1 lossis A ntawm koj li OTDR) ua ntej lub ncov ncov. Tom ntej no, tso tus cim thib ob (hu ua 2 lossis B ntawm koj li OTDR) tsuas yog tom qab qhov kev xav txog qhov kawg. OTDR yuav xam qhov poob ntawm ob lub cim.
Kev xeem OTDR yog dab tsi?
Ib Lub Sijhawm Optical Domain Reflectometer (OTDR) yog khoom siv uas ntsuas kev ncaj ncees ntawm fiber ntau cablethiab siv rau lub tsev, lees paub, tswj, thiab daws teeb meem fiber ntau optic systems.
OTDR txoj cai ua haujlwm yog dab tsi?
Ib OTDR xa luv luv pulses ntawm lub teeb rau hauv fiber ntau. Lub teeb tawg tuaj yeem tshwm sim hauv cov fiber ntau vim qhov tsis sib xws xws li cov khoom sib txuas, splices, khoov, thiab ua txhaum. OTDR tom qab ntawd kuaj thiab txheeb xyuas cov teeb liab rov qab. Lub teeb liab lub zog yog ntsuas rau ib ntus ntawm lub sijhawm thiab siv los qhia cov xwm txheej.
OTDR xam qhov deb li cas?
Ib OTDR siv cov fiber ntau "index of refraction" (IOR) tus nqilos xam qhov nrug. Qhov no yog muab los ntawm cov tuam txhab fiber ntau thiab nkag mus rau hauv qhov chaw ntawm koj OTDR. Nrog rau tus nqi IOR txoj cai, koj yuav tau txais ib qhoDaim ntawv qhia ntev fiber ntau thiab qhov tseeb nrug rau 'cov xwm txheej' xws li cov khoom sib txuas, so, thiab lwm yam.
