Raws li ib tug photoelectric hloov dua siab tshiab ntaus ntawv, ib tug optical module yog cov khoom siv tshaj plaws hauv kev sib txuas lus kho qhov muag.Ntawm cov yam ntxwv ntawm optical modules, lub peev xwm kis tau tus mob yog ib qho tseem ceeb tshaj plaws thiab muaj kev txhawj xeeb tshaj plaws.Tsis tas li ntawd, qhov kis tau tus mob nyob deb ntawm optical module yog lwm qhov tseem ceeb uas tsis tuaj yeem tsis quav ntsej.Hauv kev sib txawv thiab kev sib txuas ntawm kev sib txuas lus ntawm kev sib txuas lus optical network, cov yam ntxwv ntawm optical modules kuj txawv.
Raws li qhov kev ncua deb ntawm qhov optical module, nws tuaj yeem muab faib ua peb hom: luv-distance optical module, nruab nrab-distance optical module, thiab long-distance optical module.Qhov kev ncua deb ntawm qhov kho qhov muag yog hais txog qhov kho qhov muag module nrog qhov sib kis ntawm 30 km lossis ntau dua.Qhov xav tau rau kev xa mus ntev ntawm cov ntaub ntawv network.
Nyob rau hauv qhov tseeb siv ntawm qhov ntev-ntev optical module, qhov siab tshaj plaws kis tau tus mob nyob deb ntawm lub module tsis tuaj yeem ua tiav nyob rau hauv ntau zaus.Qhov no yog vim muaj qee qhov kev sib cais tshwm sim thaum lub sij hawm kis tau tus mob ntawm cov teeb liab kho qhov muag hauv qhov muag fiber ntau.Txhawm rau daws qhov teeb meem no, qhov kev ncua deb ntawm optical module tau txais yuav.Tsuas yog ib qho tseem ceeb wavelength yog kuv DFB laser raws li lub teeb qhov chaw, yog li zam qhov teeb meem ntawm dispersion.
Cov khoom siv kho qhov muag ntev muaj nyob hauv SFP optical modules, SFP + optical modules, XFP optical modules, 25G optical modules, 40G optical modules, thiab 100G optical modules.Ntawm lawv, qhov kev ncua deb SFP + kho qhov muag module txais EML laser tivthaiv thiab photodetector tivthaiv, uas txo cov hwj huam noj ntawm lub optical module thiab txhim kho qhov raug;qhov ntev-ntev 40G optical module txais tus tsav tsheb thiab chav hloov kho hauv qhov kev sib txuas, thiab tau txais Qhov txuas siv lub tshuab hluav taws xob kho qhov muag thiab lub tshuab hluav taws xob hloov hluav taws xob kom ua tiav qhov siab tshaj plaws kis tau tus mob ntawm 80 km.
Txawm li cas los xij, qhov kev ncua deb ntawm optical module tsis yog deb li deb tau, thiab cov kev daws teeb meem tsim nyog yuav tsum tau ua thaum tsim nyog.Cov ntawv thov nyob deb feem ntau yog nyob rau hauv thaj chaw ntawm server chaw nres nkoj, hloov chaw nres nkoj, network card chaw nres nkoj, kev saib xyuas kev nyab xeeb, kev sib txuas lus, Ethernet, thiab synchronous optical networks.
