Siv Fiber Optic Fais Meter rau Kev Tshawb Fawb Sim Optic Fais
Fiber optic cov khoom siv sib txuas lus yog raws li qhov muag hluav taws xob theem ntawm lub transmitter thiab lub receiver. Qhov txawv ntawm qhov muag fais fab theem ntawm lawv yog qhov poob ntawm kab cabling. Yuav kom ntsuas tau lub hwj chim ntawm lawv, yuav tsum muaj qhov ntsuas qhov muag fais fab coj mus ntsuas qhov kev kuaj pom.
Lub tshuab fais fab fiber optic yog feem ntau ntawm lub xeev tau ntes, teeb liab qhov teeb meem thiab cov khoom siv hluav taws xob. Los mus txuas rau ntau hom fiber ntau optic connectors siv, qee qhov kev tshem tawm cov tshuab txuas rau sab nraud tau muab. Lub zog ntsuas yog ntsuas ntawm tib lub wavelength ntawm qhov tso zis xws li multimode 850 los yog 1300nm, ib hom, 1310, 1490 thiab / lossis 1550nm, POF. Meters rau POF tshuab feem ntau yog khoov ntawm 650 thiab 850nm. Lub wavelengths siv nyob rau hauv POF systems.
Thaum ua qhov kev sim, siv lub tshuab fais fab rau qhov muag kom pom cov phooj ywg mus rau hauv lub tshuab txuas. Cov hlua txuas ntawm cov hlua khi yuav tsum yog tib hom fiber ntau thiab me me raws li lub tshuab cog thiab muaj cov khoom sib txuas nrog cov neeg nyob rau ntawm qhov chaw thiab cov cables.
Fais fab ntsuas tau kom nyeem tau hauv dB siv los ntawm ib lub teb chaws ntawm lub hwj chim kho qhov muag. Ib co metres ntawm dB tus txheeb ze kuj, tseem ceeb rau kev ntsuas poob vim qhov kev siv tus nqi yuav raug teem rau 0 dB ntawm qhov kev tso tawm ntawm qhov kev xeem. Qee lub sij hawm, lab ntsuas kuj yuav ntsuas tau rau hauv cov kab tawm ncaj li cov teb chaws, microwatts thiab nanowatts.
Cov Kev Kuaj Fais Fab Kev Xeem Optical Option:
Qhib lub hwj chim ntsuas lub sij hawm kom sov so.
Teem lub 'meter' rau wavelength ntawm qhov chaw thiab "dBm" ntsuas qhov ntsuas fais fab.
Ntxuav tag nrho cov connectors thiab mating adapters.
Muab cov hlua khi los sis cov hlua fiber ntau rau qhov twg yog qhov kuaj tau lub zog los yog disconnect cable ntawm receiver.
Muab lub cav fais fab txuas mus rau qhov xaus ntawm cable thiab nyeem ntsuas fais fab.
Yuav kom txo txoj kev tsis meej, koj yuav tsum ua kom lub ntsuas qhov muag fais fab raws li cov chaw lag luam tau teev tseg. Ntxuav tag nrho cov connectors thiab tshem tawm cov tshuab pa adapter periodically los ntxuav cov adapters thiab fais fab tuag ntsuas. Yuav tsum tsis txhob muaj kev ntxhov siab, thov tsis txhob khoov cov kab mob fiber ntau hauv lub sijhawm kuaj.
Kev kuaj fais fab ntawm Optic tsuas yog ib qho tseem ceeb ntawm kev kuaj fiber ntau. Feem ntau cov txheej txheem kev sim rau fiber optic tivthaiv tau raug hloov los ntawm cov kev cai thoob teb chaws thiab thoob ntiaj teb uas tau hloov mus rau cov txheej txheem los ntsuas qhov tsis muaj qhov muag fais fab, cable thiab connector poob thiab qhov teebmeem ntawm ntau qhov chaw xws li kub, siab, flexing, thiab lwm yam. cov cuab yeej siv ntawm optic optical fais fab, optical teeb qhov muag, OTDR thiab cov tshuaj ntsuam tshawb xyuas fiber ntau.
