Nws yog tsuas yog siv rau kev sib kis ntev thiab tuaj yeem ncav cuag 150 txog 200km. LD lossis LED nrog cov kab nqaim kab hluav taws xob tau siv los ua cov khoom siv hluav taws xob.
Tswvyim
Lub tib hom nyob rau hauv optical module yeej hais txog tsuas yog hom ntawm optical fiber. Ib hom kho qhov muag siv yog lub khoos phis tawm siv nrog tib hom kho qhov muag. Cov LED nrog lub nqaim LD lossis cov kab hluav taws xob tau siv los ua lub teeb ci, uas tuaj yeem xa cov ntaub ntawv qhia tau zoo tshaj plaws, yog li cov kis tau mus ntev heev. Lub logo rau ntawm tib hom kev tsim kho qhov muag yog" SM", thiab cov fiber ntau kho qhov muag yog daj, feem ntau nrog lub yoj hluav taws ze ntawm lub qhov rais 1310nm thiab 1550nm.
Thov
Bandwidth muaj peev xwm ntawm ib hom kho qhov muag module ua rau nws qhov kev xaiv zoo tshaj plaws rau kev kub ceev thiab cov ntaub ntawv ntev kis. Nws yog tsuas yog siv rau LR, ER / ZR thiab lwm qhov kev sib kis ntev thiab qhov kis tau tus mob siab, xws li kev sib tw ntev ntawm txoj kab kev sib kis thiab cov txiv neej kev tsim kho. Daim teb thov dav dav, suav nrog telecom, cable TV, kev tsheb nqaj hlau, kev tub rog, kev nyab xeeb nyiaj txiag, kev lis kev cai, kev tsav dav hlau, thauj khoom, hluav taws xob, dej kev txuag, roj teb thiab lwm yam ntawm cov ntaub ntawv xov xwm broadband thiab xav kom muaj kev ntseeg siab ntawm cov ntaub ntawv xa lossis teeb tsa nce IP cov ntaub ntawv xa mus rau ntiag tug network, yog broadband network, broadband cable network thiab ntse broadband optical fiber, optical fiber rau lub tsev tsim lub zos los ua cov khoom siv zoo tshaj plaws.
Tib hom kho qhov muag module siv tshuab ua haujlwm siv tau
Ib leeg-hom kho qhov muag cov qauv siv fiber ntau yog pheej yig, tab sis cov cuab yeej siv tib hom yog kim ntau dua li cov cuab yeej siv ntau hom zoo sib xws. Cov khoom siv tib hom tuaj yeem ua haujlwm ntawm ob hom tib thiab ntau hom kho qhov muag, thaum cov cuab yeej siv ntau hom tau txwv rau ntau hom kho qhov muag.
Cov lus sau rau kev siv qhov ntev nyob deb ntawm tib hom kho qhov muag module
Ntev nrug ib-hom kho qhov muag module muaj nruj raws ntawm cov hwj huam ntau ntawm tau txais lub teeb. Yog tias qhov tau txais qhov mob siab dhau, qhov kho qhov muag tsis ua haujlwm yuav poob.
1. Tsis txhob tso' t sai li sai tau tom qab ib hom tib hom kho qhov muag rau cov khoom siv coj los txuas rau cov khoom siv kho qhov muag, kom siv cov kab hais kom ua kab sib kis transceiver kuaj interface nyeem module kom tau txais lub teeb ci hluav taws xob, xyuas kom pom tias lub zog luminous nyob rau hauv coj mus muag ntau yam, lub zog siv hluav taws xob tsis yog + 1 dB thiab outliers, tsis muaj' t txuas optical fiber rau software feem ntau tso saib tau txais lub teeb hluav taws xob yuav yog - 40 dB lossis tus nqi qis dua.
2. Raws li cov xwm txheej ntawm kev ua haujlwm, nws raug pom zoo kom siv lub ntsuas hluav taws xob kho qhov hluav taws xob los ntsuas qhov tau txais thiab lub zog luminescent. Tsuas yog nyob rau hauv qhov tau txais ntau yam tuaj yeem kho qhov muag fiber ntau tau txuas nrog qhov ntev ntev ntawm tib hom kev kho qhov muag.
3. Tsis muaj qhov xwm txheej twg tuaj yeem ua rau fiber ntau qhov hluav taws xob tau ncaj qha mus rub los sim cov qhov ntev-tib hom kev xaiv kho qhov muag. Yog tias tsim nyog, lub kho kom zoo nkauj ntawm lub ntsej muag yuav tsum txuas nrog kom ua kom tau txais lub zog kho qhov muag nyob hauv qhov tau txais ntau kom coj los ntsuas qhov kev sib tw.
4. Yog hais tias ntev-deb tib-hom kho qhov muag hom siv, lub zog tau txais yuav tsum muaj qee yam npoo. Lub zog tau txais tiag tiag yog ntau tshaj li 3dB tshwj tseg piv nrog kev txais lub siab zoo.
5. Feem ntau, ntau hom kho qhov muag thiab ntau hom kho qhov muag siv fiber ntau, tib hom kho qhov muag thiab tib hom kho qhov muag tau siv, yog ib sab muaj ntau hom khoom siv, ib sab yog hom kho qhov muag fiber ntau, ib leeg ntau hom hloov dua siab tshiab. Yog hais tias qhov kis tau mus deb yog luv heev, tib hom kho qhov muag module tuaj yeem hloov mus ib ntus los ntawm ntau hom kho qhov muag, tab sis tsis yog lwm txoj hauv kev, vim tias qhov laser chaw ntawm ntau hom kho qhov muag module loj heev, nrog 62.5 nm lossis 50 m, thaum lub ntsiab lus fiber ntawm ib hom kho qhov muag fiber ntau tsuas yog 9 m, yog li lub teeb hluav taws xob ntawm lub teeb tsis tuaj yeem txuas mus rau hauv tib hom kev kho qhov muag.
