Multiplexed Wavelength Stability, Insertion poob, thiab lwm yam kev ua tau zoo
May 08, 2018

Qis Wavelength Division Multiplexer, Twv Wavelength Division Multiplexing, hu ua DWDM. Nws yog ib qho tseem ceeb ntawm cov khoom siv fais fab ntawm cov tshuab fiber ntau hauv cov qauv ntom ntom taus (DWDM). Nws yog ib qho tseem ceeb ntawm cov txheej txheem, uas yog tsim los ntawm cov kab ntom ntom ntom ntau qhov sib txuas. Nws ncaj qha txiav txim qhov kev ua tau zoo xws li kev muaj peev xwm, kev ruaj ntseg ntau qhov kev ruaj ntseg, thiab qhov chaw poob. Kev Sib Txuas Feem Txuas Ntev Multiplexers kuj muaj peev xwm muab tau los ntawm ntau yam ntawm lwm yam khoom siv tseem ceeb rau DWDM, xws li cov kab txuas cov kab sib txuas-tagnrho-optical kev sib txuas lus rau taw-rau-point kev pabcuam rau cov kev pabcuam broadband thiab kev taw qhia txog lub suab; ntxiv / dais li- Rau qhov kev qhia txog wavelength ntawm cov lag luam tawm / nce; comb lim - rau tiam ntawm ntau lub wavelength cov teeb ci thiab kev ntsuas ntawm cov spectrum; wavelength xim xaiv - kev taw qhia ntawm kev sib txawv ntawm ntau lub wavelengths, thiab lwm yam., thiaj li rau ntom wavelength division multiplexers Kev tshawb fawb thiab kev lag luam muaj qhov tseem ceeb ntawm theoretical thiab zoo ntawm kev ua lag luam.

Hauv kev khiav lag luam, thiaj li tsim nyog siv cov kev pabcuam siv hauv kev sib txuas ntawm 1.55pm thaj tsam tsawg-loss ntawm ib hom fiber ntau, nws yog qhov tsim nyog yuav tau faib cov cheeb tsam tsawg tsawg ntawm cov fiber ntau hauv ntau txoj kev kho qhov muag raws li qhov sib txawv frequencies thiab wavelengths. Lub tshuab kho qhov muag tsim tsa cov cab kuj, uas yog peb hu lub teeb yoj, thiab tib lub sij hawm siv qhov kev sib tw sib xyaw ua ke ntawm cov ntawv sib txawv ntawm cov xa tawm ntawm cov xa tawm ntawm cov xa tawm, collectively hloov cov kev teeb tsa ua ke rau hauv ib lub tshuab ua fiber ntau ua cov teeb liab kis. Thaum kis tau mus rau qhov kawg, cov wavelengths tau muab tso ua ke nrog siv qhov kev ntsuas qhov muag. Txoj kev sib cais ntawm cov teeb meem ntawm cov teeb sib txawv tsis zoo rau hauv thawj lub xeev pib ua haujlwm ntawm kev xa mus rau ntau tshaj ib qho kev sib txawv ntawm qhov sib txawv ntawm fiber ntau hauv fiber ntau.
