O-band Passive DWDM 100G kev daws teeb meem xa mus txog 16x 100G cov ntaub ntawv ntws hauv 20/30km yam tsis muaj teeb liab amplification!
O-band optical wavelength ntau yog siv ntau yam kev daws teeb meem hauv kev sib txuas lus niaj hnub no.Ib qho ntawm cov no yog xWDM system, nrog EDGE Optics muab ib lub wavelength 100G QSFP28 O-band xWDM pluggable optical transceiver thiab passive O-band MUX / DeMUX filter device.Lub transceiver ua haujlwm nyob rau hauv LAN-WDM daim phiaj ntawm 16 wavelengths hauv O-band los ntawm 1295nm mus rau 1312nm ntawm 200GHz channel intervals.Cov qauv no yuav tsum muaj ib hom G.652 fiber ntau rau kev ua haujlwm ib txwm muaj.
Txuas ib qho channel txuas ncaj qha los ntawm ib qho QSFP28 mus rau lwm QSFP28 - yam tsis muaj MUX lim, qhov siab tshaj plaws txuas mus txog 30km.Txawm li cas los xij, yog siv 8ChMUX/DeMUX lim system, qhov siab tshaj plaws txuas txuas yog txo mus rau 25km vim filter insertion losses.Thiab nruab nrog 16ChMUX/DeMUX lim -- 20km.
Lub passive DWDM100GQSFP28O band xWDM transceiver yog tsim los nrog CAU-4 tus tswv hluav taws xob interface uas muaj 4 NRZ kab.Qhov no ua kom muaj kev sib raug zoo nrog cov tuam txhab hloov pauv feem ntau.Four hluav taws xob NRZ kab txuas nrog PAM4 kho qhov muag teeb liab kab nrog kev sib xyaw FEC nrog kev pab los ntawm ib tug gearbox nyob rau hauv lub module.Qhov kho qhov muag Circuit Court yog thawj modulated teeb liab qhov chaw, tsav los ntawm ib tug laser ntawm ib tug tshwj xeeb wavelength channel.
O-band passive MUX/DeMUX lim kua tso cai rau cov ntaub ntawv xa mus txog li 1.6Tbps nyob deb ntawm 20 km.Qhov no ua tiav nrog Kev daws 1, uas nta 16-channel MUX/DeMUX lim thiab tag nrho-channel 100G transceivers.
Solution 1 -- Dual Fiber O-band DWDM 100G passive kev twb kev txuas, nrog 16 100g-QSFP28 O ntu transceivers, thiab ob lub dual fiber O-band DWDM 16-channel passive lim:
Kev daws 2 -- Ib leeg-fiber O-band DWDM 100G passive kev twb kev txuas nrog 16 100g-QSFP28 O-band transceivers thiab ob ib leeg-fiber O-band DWDM 8-channel passive lim:
