Cov khoom siv kho qhov muag yog lub teeb liab photoelectric hloov dua siab tshiab, uas tuaj yeem muab tso rau hauv lub network teeb liab transceiver cov cuab yeej xws li routers, keyboards, thiab cov khoom sib kis.Ob qho tib si hluav taws xob thiab kho qhov muag teeb liab yog cov teeb liab sib nqus.Kev sib kis ntau yam ntawm cov teeb liab hluav taws xob yog txwv, thaum cov teeb liab kho qhov muag tuaj yeem kis tau sai thiab deb dua.Txawm li cas los xij, qee cov khoom siv tam sim no paub txog cov teeb liab hluav taws xob, yog li muaj cov hloov pauv photoelectric.
Vim lub high bandwidth thiab ntev kis tau tus mob nyob deb ntawm optical fiber kis tau tus mob, thaum cov tsoos cable kis tau tus mob deb yog luv luv thiab susceptible rau electromagnetic cuam tshuam, thiaj li mus cuag cov kis tau tus mob nyob deb ntawm kev sib txuas lus, optical fiber yog yeej siv rau kis tau tus mob.Nrog kev koom tes ntawm cov khoom siv kho qhov muag, cov teeb liab hluav taws xob tuaj yeem hloov mus rau hauv cov teeb liab kho qhov muag rau kev sib kis hauv cov khoom siv kho qhov muag, thiab tom qab ntawd hloov los ntawm cov teeb liab kho qhov muag mus rau cov teeb liab hluav taws xob kom tau txais los ntawm cov khoom siv network, yog li txuas ntxiv qhov kev sib txuas ntawm kev sib txuas lus digital.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm optical module ntawm qhov kawg xa tawm yog nkag mus rau lub teeb liab hluav taws xob nrog qee tus lej lej los ntawm cov ntiv tes kub lub davhlau ya nyob twg, thiab tom qab ntawd tsav lub laser xa tawm cov teeb liab kho qhov muag ntawm tus nqi sib xws tom qab ua tiav los ntawm tus tsav nti. ;
Lub hauv paus ntsiab lus ua haujlwm ntawm qhov kawg tau txais yog hloov cov teeb liab uas tau txais rau hauv lub teeb liab hluav taws xob los ntawm kev ntes, thiab tom qab ntawd hloov cov teeb liab tsis muaj zog tam sim no rau hauv lub teeb liab voltage los ntawm transimpedance amplifier, yog li amplifying lub teeb liab hluav taws xob, thiab tom qab ntawd tshem tawm cov overvoltage. teeb liab los ntawm limiting amplifier.Lub teeb liab siab lossis tsis tshua muaj hluav taws xob ua rau cov zis hluav taws xob teeb liab ruaj khov.
