QSFP 40G LR4 optical module tau dav siv hauv 40G network, nws suav nrog ob hom QSFP 40G LR4 CWDM optical module thiab QSFP 40G LR4 PSM optical module.
CWDM thiab PSM yog dab tsi?
CWDM (Coarse Wavelength Division Multiplexing) yog hais txog coarse wavelength division multiplexing. CWDM yog ib hom WDM (wavelength division multiplexing). Nws tuaj yeem xa thiab tau txais cov teeb liab ntawm ntau cov channel ntawm ib qho fiber ntau optical. Nws feem ntau yog siv hauv kev sib txuas lus. point-to-point structured thaiv kab.
PSM (Parallel Single Mode Fiber) yog hais txog kev sib txuas ib leeg-hom fiber ntau tshuab. Tsis zoo li CWDM optical modules uas xa lossis tau txais cov teeb liab ntawm ntau txoj hauv kev ntawm ib lub fiber ntau, PSM tuaj yeem tau txais thiab xa cov teeb liab ntawm plaub qhov sib npaug.
Txheej txheem cej luam ntawm QSFP 40G LR4 CWDM Optical Transceiver
QSFP 40 GLR4 CWDM module feem ntau yog hais txog QSFP ntxiv rau 40G LR4 optical module, uas muaj LC duplex interface, plaub txoj kev ywj pheej transceiver, thiab txhua channel txhawb tus nqi ntawm 10Gbps. Yuav kom txo qis dispersion, lubQSFP 40 GLR4 CWDM optical module yuav tsum tau siv nrog ib hom fiber ntau, thiab qhov siab tshaj plaws kis tau tus mob yog 10 kilometers.
Lub transmitter ntawm QSFP 40G LR4 CWDM optical module siv 4-channel faib tawm tswv yim laser (DFB) array los hloov 4-channel 10Gbps hluav taws xob teeb liab rau hauv 4-channel CWDM optical signals, thiab tom qab ntawd multiplex lub 4-channel CWDM optical signals rau hauv ib leeg-channel 40Gbps optical signal Transmission yog nqa tawm ntawm ib hom optical fiber ntau; qhov tau txais qhov kawg de-multiplexer lub 40Gbps kho qhov muag teeb liab rau hauv 4-channel CWDM kho qhov muag teeb liab thiab hloov nws mus rau hauv 10Gbps hluav taws xob teeb liab los ntawm cov khoom siv kho qhov muag.
Lub hauv paus wavelengths ntawm 4 CWDM raws ntawm QSFP 40G LR4 CWDM yog 1271nm, 1291nm, 1311nm thiab 1331nm, uas ua raws li tus qauv ITU-T G694.2.
Txheej txheem cej luam ntawm QSFP 40G LR4 PSM optical module
QSFP 40G LR4 PSM optical module muaj MTP / MPO interface, muab 4 txoj kev sib txuas lus ywj pheej thiab txais tos, txhua qhov channel tuaj yeem khiav ntawm 10G tus nqi ntawm ib hom fiber ntau, thiab kev sib kis tau ntev txog 10 km. Lub transmitter module ntawm QSFP 40G LR4 PSM tau txais hluav taws xob input teeb liab sib xws nrog CML, thiab tom qab ntawd lub receiver module hloov cov teeb liab inputs thaum uas tig mus rau hauv cov teeb liab tso zis los ntawm cov duab ntes array, thiab cov teeb liab tawm ntawm lub receiver module kuj sib xws nrog CML. Feem ntau, muaj cov lus qhia pins hauv MTP / MPO interface qhov (socket), uas tuaj yeem siv los kho qhov tseeb interface thaum ntxig lub module. Thaum tus neeg siv ntxig cov fiber ntau jumper nrog MTP / MPO connector rau hauv QSFP ntxiv rau 40G LR4 PSM optical module, nws tuaj yeem zam qhov teeb meem ntawm fiber ntau puas vim yog qhov tsis zoo ntawm qhov sib cuam tshuam.
Koj tuaj yeem xaiv qhov tsim kho qhov muag module raws li koj xav tau.
