Qhov no yog hais txog kev sib txuas ntawm cov khoom siv kho qhov muag mus rau fiber ntau optic thaj cable, uas tuaj yeem txuas tau ntawm ib hom lossis multimode fiber optic cable. Cov hauv qab no yog kev tshuaj xyuas ntawm qhov no raws li qhov sib txawv interfaces. Tam sim no, cov khoom siv kho qhov muag tseem ceeb ntawm kev ua lag luam yog: MPO, LC, S ...

Tam sim no, muaj FBG, FB thiab DFB lasers, Ntawm lawv, feem ntau siv lasers yog FP thiab DFB. FBG: Fiber Bragg Grating. FP: Fabry-Perot, Fabry-Perot Laser Diode DFB: Tshaj Tawm Cov Lus Qhia Laser, Tshaj Tawm Cov Lus Qhia Laser Diode Rau cov khoom siv feem ntau siv FB thiab DFB. DFB las...

Hauv tsab xov xwm no kuv yuav tham txog dab tsi ua rau poob hauv fiber ntau optics kis tau tus mob. Cia peb kawm… Yog vim li cas vim li cas fiber ntau optical hloov qhov nruab nrab thiab ntev-ntev kis tau tus mob network cables yog vim optical fiber kis tau tus mob tsawg, thiab nws poob yog feem ntau muab faib ua cov nram qab no: ...

(i) Center wavelength Qhov ua haujlwm wavelength ntawm optical module yog qhov tseeb, tab sis yuav muaj qhov sib txawv ntawm ib hom thiab ntau hom. Tom qab ntawd cov lus qhia feem ntau muaj npe raws li qhov nruab nrab wavelength. Chav tsev ntawm nruab nrab wavelength yog nanometer (nm), ...

Raws li qhov sib txawv ntawm kev tsim kho lub sij hawm: Optical modules muab faib ua ob hom: PON optical modules thiab tsoos optical modules. Thaum siv cov khoom siv kho qhov muag ib txwm: Cov teeb liab kis tau tus mob optical yog point-to-point (P2P: ib qho kis mus rau ib qho), lub module ...

Nyob zoo, Zoo siab txais tos. Cia peb kawm qhov kev sib piv ntawm GPON thiab EPON optical modules hauv cov lus piav qhia yooj yim. GPON optical module muaj kev ua tau zoo dua li EPON optical module. Hais txog kev ceev, downlink zoo dua EPON; Hais txog kev lag luam, GPON npog ntau qhov dav; Los ntawm kis ...
