Ua ntej, sfp28 optical module xa lub teeb pom kev los ntawm 80 km optical fiber, tom qab ntawd nws ua kom nrov nrov los ntawm optical fiber amplifier, tom qab ntawd nws kis tau los ntawm kev faib khoom tawg nthe qauv thiab kho kom haum attenuator, thaum kawg nws nkag mus txais qhov kawg ntawm sfp28 optical module. Thaum lub zog txais hluav taws xob tsawg dua - 10dBm, tus nqi yuam kev ntawm qhov ntsuas hluav taws xob hauv kev sib txuas lus kho qhov muag yog qis dua 10-12, thiab nws tau dhau qhov kev xeem tiav.
25g DWDM sfp28 lub teeb ntev kis tau zoo muab cov kev daws teeb meem tshiab qis rau cov qhua tuaj noj mov. Feem ntau, thaum cov kis tau mus deb ntawm 25g tus nqi yog ntau dua 40km, kev sib kis hluav taws xob kis tau xav tau, tab sis tus nqi ntawm kev sib koom tes optical module yog kim heev. Tus nqi ntawm sfp28 optical module yog qis dua tus nqi ntawm qhov muag teeb kho qhov muag. Txawm hais tias xav tau fiber ntau lub zog thiab cov qauv tsim kev them nyiaj, txheej txheem ntawm 25g DWDM sfp28 + optical amplifier + dispersion raug them tseem muaj qhov txiaj ntsig zoo.
Txhawm rau txais tos 5g era, kuj muaj cov khoom lag luam hauv qab no:
SFP28 SR 、 LR 、 ER
SFP28 Bidi 10km 、 30km
sfp28 CWDM 12 yoj 1270 ~ 13701470 ~ 1570
LAN WDM 9 lub xov tooj cua
25g sfp28 series ntawm cov khoom lag luam tau tiav ntau lawm nrog kev ua haujlwm ruaj khov thiab tus nqi siab, uas tuaj yeem ua tau raws li qhov xav tau ntawm cov neeg siv khoom hauv cov ntawv thov sib txawv.
