Hauv kev sib txuas lus kho qhov muag fiber ntau, thaum optical fiber xa cov teeb liab kho qhov muag, cov teeb liab kho qhov muag yuav attenuate raws txoj kev fiber ntau kis tau tus mob, thiab qhov kis tau tus mob yog txwv los ntawm optical fiber attenuation. Txhawm rau xa cov teeb liab ntxiv, peb yuav tsum txhim kho cov teeb liab optical. Txoj kev niaj hnub ntawm kev txhim kho cov teeb liab kho qhov muag yog siv cov regenerator, tab sis nws muaj ntau qhov tsis zoo, vim hais tias lub regenerator tsuas tuaj yeem ua haujlwm raws li qhov txiav txim siab me ntsis tus nqi thiab cov teeb liab hom, thiab qhov sib txawv me ntsis thiab cov teeb liab hom xav tau cov regenerators sib txawv. Yog li ntawd, txhua channel xav tau ib tug regenerator, Thaum kawg, tus nqi ntawm lub network yuav siab heev. Qhov blog no qhia txog daim ntawv thov ntawm optical amplification technology nyob rau hauv nruab nrab thiab ntev-ntev optical modules.
Yog li ntawd, ib tug tshiab technology los txhim kho optical teeb liab yog yug los, uas yog hu ua optical amplification technology. Lub hauv paus ntsiab lus ntawmoptical amplifieryog kom amplify optical teeb liab los ntawm stimulated hluav taws xob los yog stimulated scattering. Optical amplification technology yog siv nyob rau hauv nruab nrab thiab ntev-ntev optical modules. Txij li thaum lub teeb liab kho qhov muag ntawm qhov kawg kis tau raug attenuated mus rau ib theem me me tom qab qhov kev ncua deb ntawm optical fiber ntau kis tau tus mob, yog hais tias lub attenuated optical teeb liab txuas ncaj qha mus rau lub optical detector ntawm qhov kawg tau txais, lub teeb liab optical ntawm lub transmitting kawg yuav tsis tau. yuav zoo tag nrho.
Yog li ntawd, txhawm rau txhim kho qhov rhiab heev ntawm qhov kawg tau txais, optical amplifiers tau ntxiv rau pem hauv ntej ntawm lub ntsuas qhov muag ntawm qhov tau txais qhov kawg hauv cov khoom siv kho qhov muag kom nthuav dav cov teeb liab attenuated kho qhov muag ib zaug thiab tom qab ntawd txuas mus rau qhov ntsuas qhov muag, yog li ntawd. cov teeb liab kho qhov muag ntawm qhov kawg xa tuaj yeem rov qab tau zoo kom ua tiav lub hom phiaj ntawm kev sib kis nruab nrab thiab ntev.
Txawm hais tias tam sim no cov txheej txheem ntawm optical transceiver yog cov paub tab, cov txiaj ntsig ntawm optical module tseem tsis siab heev, yog li cov nqi tsim khoom ntawm optical module yog siab.
Qhov nruab nrab thiab ntev-ntev kho qhov muag module muaj cov khoom siv kho qhov muag thiab lub teeb liab optical amplification unit. Lub optical amplifier tuaj yeem siv los ua kom pom cov teeb liab uas tau txais, thiab cov teeb liab optical amplified yog tso tawm rau qhov ntsuas qhov muag. Tus maub los tau hloov kho qhov nce ntawm qhov kho qhov muag amplifier raws li lub zog kho qhov muag thiab qhov hluav taws xob hluav taws xob tau coj los ntawm lub ntsuas qhov muag.
