Zuag qhia tag nrho, lub optical transmitter yog ib tug sophisticated ntaus ntawv uas plays ib tug tseem ceeb luag hauj lwm nyob rau hauv lub kis ntawm high-ceev cov ntaub ntawv nyob rau hauv ntev kev deb siv fiber optic cables.
Dab tsi ntawm Fiber Optic Cable yog sib xws nrog Optical Transmitter
Thaum nws los txog rau kev xaiv cov fiber ntau optic cable uas sib haum nrog koj lub tshuab xa hluav taws xob, muaj ntau yam los xav txog. Nov yog cov ntsiab lus tseem ceeb uas yuav tsum nco ntsoov:
Hom
Hom fiber ntau optic cable koj xaiv nyob ntawm seb cov kev xav tau tshwj xeeb ntawm koj lub transmitter optical. Muaj ob hom fiber ntau optic cables
ib hom thiab multimode. Ib hom yog feem ntau siv rau kev ncua ntev thiab kev siv ceev dua, thaum multimode yog siv rau luv luv thiab qis-ceev daim ntaub ntawv.
Core loj
Qhov loj me ntawm fiber ntau optic cable yog lwm qhov tseem ceeb rau kev txiav txim siab. Qhov no yog hais txog txoj kab uas hla ntawm cov tub ntxhais fiber ntau, uas tuaj yeem nyob ntawm 8 microns txog 62.5 microns. Cov tub ntxhais loj tuaj yeem cuam tshuam qhov kev ncua deb ntawm lub teeb liab tuaj yeem taug kev thiab tus nqi ntawm cov teeb liab poob uas tshwm sim.
Lub wavelength
Lub wavelength ntawm optical transmitter yog lwm qhov tseem ceeb uas yuav tsum tau xav txog thaum xaiv cov fiber ntau optic cable. Ntau hom fiber ntau optic cables yog tsim los ua hauj lwm nrog cov wavelength tshwj xeeb, yog li nws yog ib qho tseem ceeb los xyuas kom meej tias koj xaiv cable yog sib xws nrog koj optical transmitter.
Bandwidth
Bandwidth yog tus nqi ntawm cov ntaub ntawv uas yuav kis tau los ntawm fiber ntau optic cable. Cov kab hluav taws xob bandwidth siab dua feem ntau kim dua tab sis muaj peev xwm xa cov ntaub ntawv ntau dua nyob deb.
Jacket khoom
Cov khoom siv lub tsho ntawm lub fiber optic cable kuj tseem ceeb heev. Cov tsho sib txawv yog tsim los tiv thaiv cov kab hluav taws xob los ntawm ntau yam ib puag ncig, xws li ya raws, tshuaj lom neeg, thiab qhov kub thiab txias.

Txhawm rau kom lub laser ua haujlwm, yuav tsum muaj qee qhov tam sim no. Muaj qee qhov kev sib raug zoo ntawm qhov loj ntawm qhov tam sim no thiab lub teeb siv. Thaum qhov tam sim no nce, lub teeb siv zog nce sharply. Qhov no qhia tau hais tias lub laser tau pib ua haujlwm. Qhov no ua rau lub laser ua haujlwm. Qhov tam sim no hu ua threshold current. Qhov me me, qhov zoo dua, vim nws twb tau qhib lub laser ua haujlwm.
Yog tias qhov pib tam sim no tseem nce ntxiv, qhov chaw tso zis saturation yuav raug tsim. Thaum qhov chaw saturation tam sim no ncav cuag ib qho nqi, lub teeb liab yuav raug xa mus. Nyob rau hauv cov nqe lus ntawm lub hwj chim yuav tsum tau rau optical fiber kis tau tus mob, tso zis hwj chim ntawm ob peb megawatts nyob rau hauv linear cheeb tsam yuav ua tau raws li qhov yuav tsum tau ntawm kev ncua deb ntawm cov teeb liab thiab cov ntaub ntawv. Ntxiv nrog rau qhov muaj zog ntawm lub teeb, kev sib kis tau zoo ntawm lub teeb kuj muaj feem xyuam rau cov teeb meem xws li spectrum thiab suab nrov.
Multi-wavelength spectrum tsis haum rau kev sib kis ntawm high-zoo analog teeb liab. Txawm hais tias nws ua haujlwm hauv ib hom, nws cov emission spectrum muaj qhov dav. Qhov dav dav dua, qhov ntshiab lub teeb yoj dhau los thiab ntau lub sij hawm-coherent nws ua. Qhov ntawd yog lub teeb nthwv dej nrog kev sib raug zoo. Lub teeb nthwv dej nrog kev sib raug zoo tsis xav tau lo ntsiab muag thiab lwm yam khoom siv los hloov nws mus rau hauv qhov chaw me me, thiab nws yog qhov tsim nyog rau qhov xwm txheej ntawm cov fibers optical.
Lub Optical Transmitter Li Cas Hloov Cov Hluav Taws Xob Hluav Taws Xob rau hauv Optical Signals
