Optical moduleyog tsim los ntawm transmitter thiab receiver. Thaum lub transmitter txuas nrog lub receiver los ntawm optical fiber, yog tias qhov yuam kev me ntsis ntawm tag nrho lub cev tsis ua tiav cov txiaj ntsig xav tau, nws puas yog qhov teeb meem ntawm lub transmitter lossis tus txais qhov teeb meem? Ib qho khoom siv kho qhov muag ua tiav, txhawm rau kom ntseeg tau tias cov khoom zoo, yuav tsum mus dhau ntau cov kauj ruam ntawm kev sim ua ntej xa khoom. Kev ntsuas cov khoom thiab kev sib cuam tshuam ntawm cov khoom siv kho qhov muag, tshwj xeeb tshaj yogoptical modules, yog qhov tseem ceeb. Yog li cas kuaj qhov ua tau zoo ntawm optical module?
Cov kauj ruam
1. Ua ntej, lub hwj chim kho qhov muag, tau txais rhiab heev, qhov muag daim duab, thiab kev ploj tuag piv thiab qhov yuam kev yog ntsuas. Cov khoom siv uas xav tau yog kho qhov muag attenuator, kho qhov muag lub hwj chim ntsuas, qhov yuam kev code meter (kom kho lub hwj chim kho qhov muag thiab rhiab heev los ntawm tus nqi) thiab daim ntawv qhov muag.
2. Ua qhov ntsuas kub thiab qis qis los xyuas qhov ruaj khov ntawm cov khoom.
3. Kuaj cov khoom sib xws hauv qhov hloov kom ntseeg tau tias muaj kev sib haum xeeb.
4. Thaum kawg, lub ntsej muag kawg tau kuaj pom ntawm lub ntsej muag fiber ntau lub ntsej muag. Qhov chaw nres nkoj tau ntxuav nrog tus cwj mem ntxuav kom huv thiab xyuas kom zoo.
Nco ntsoov
Thaum kuaj, nws yuav tsum tau them sai sai rau lub wavelength thiab cov duab ntawm cov zis waveform ntawm lub transmitter, nrog rau kev sib tham siab ntev thiab bandwidth ntawm lub receiver. Qhov zoo ntawm cov teeb liab input siv los kuaj lub transmitter yuav tsum zoo txaus. Tsis tas li ntawd, qhov zoo ntawm kev ntsuas hluav taws xob yuav tsum tau lees paub los ntawm dither thiab qhov muag daim ntawv ntsuas. Qhov muag daim ntawv qhia kev ntsuas yog ib txoj hauv kev los xyuas cov zis waveform ntawm emitter, vim tias daim ntawv qhia qhov muag muaj cov ntaub ntawv nplua nuj thiab tuaj yeem cuam tshuam tag nrho cov kev ua tau zoo ntawm emitter.
