Raws li ib feem tseem ceeb ntawm kev sib txuas lus optical network, optical fiber module ua haujlwm li photoelectric hloov dua siab tshiab, kom cov teeb liab kis tau rau hauv optical fibers.Yog li, koj puas paub yuav ua li cas paub qhov txawv ntawm ib qhooptical fiber module yog ib homlos yog ntau hom?Nov yog ob peb txoj hauv kev kom paub qhov txawv ntawm ntau hom fiber ntau modules thiab ib hom fiber ntau modules.
Ua ntej, peb tuaj yeem saib cov wavelength tsis ntawm optical fiber module.Feem ntau, lub wavelength ntawm optical fiber module yog 850nm, thiab cov optical fiber module yog multimode optical fiber module.Lub wavelength ntawm ib hom optical fiber module feem ntau yog 1310nm, 1330nm, 1490nm, 1550nm, thiab lwm yam. Tsis tas li ntawd, CWDM xim lub teeb module thiab DWDM xim lub teeb module yog ob hom fiber ntau modules.
Qhov thib ob, peb tuaj yeem saib qhov kev sib kis ntawm fiber ntau optic modules.Qhov kev ncua deb ntawm multimode fiber optic modules feem ntau tsawg dua 2km, uas yuav tsum tau siv nrog multimode fiber ntau jumpers.Qhov kev ncua deb ntawm ib leeg-hom optical fiber module feem ntau yog siab dua 2km, Gigabit ib hom optical fiber module tuaj yeem kis tau deb li 160km, thiab 10-Gigabit ib hom optical fiber ntau tuaj yeem xa tau deb li 100km.
Thib peb, peb tuaj yeem saib cov hom khoom siv kho qhov muag ntawm fiber ntau optic module.Lub teeb emitting ntaus ntawv ntawm multimode fiber optic module yog VCSEL, thiab lub teeb emitting ntaus ntawv ntawm ib hom fiber optic module yog DFB, EML, FP, thiab lwm yam.
Plaub, peb tuaj yeem txiav txim ib hom lossis ntau hom los ntawm cov xim ntawm lub nplhaib rub ntawm fiber ntau optic module.Cov xim ntawm lub nplhaib rub ntawm multimode fiber optic module nrog tus nqi sib kis tsawg dua 40G (tsis suav nrog 40G) feem ntau yog xim dub, 40G thiab siab dua (nrog rau 40G) Cov xim ntawm lub nplhaib rub ntawm multimode fiber optic module yog beige.Lub nplhaib rub ntawm ib hom fiber ntau module nrog lub wavelength ntawm 1310nm yog xiav.Tsis tas li ntawd, muaj lwm yam xim ntawm rub lub nplhaib.Lawv yog txhua hom fiber ntau modules.
Paub hom fiber ntau (ib hom /ntau hom) ntawm fiber ntau optic module pab peb xaiv qhov sib txuas fiber ntau jumper kom raug.
