40KM 40G QSFP + Optical Transceiver Module
CovHUAQ 40 Eyog ib tug transceiver module tsim rau 40Km optical kev sib txuas lus daim ntaub ntawv.Tus qauv tsim yog ua raws li 40GBASE-ER4 ntawm IEEE P802.3ba tus qauv.Lub module hloov 4 inputs channels (ch) ntawm 10Gb / s cov ntaub ntawv hluav taws xob rau 4 CWDM optical signals, thiab multiplexes rau hauv ib qho channel rau 40Gb / s optical kis tau tus mob.Reversely, nyob rau sab receiver, lub module optically de-multiplexes ib tug 40Gb / s input rau 4 CWDM channel signals, thiab converts lawv mus rau 4 channel tso zis hluav taws xob cov ntaub ntawv.
Lub hauv paus wavelengths ntawm 4 CWDM raws yog 1271, 1291, 1311 thiab 1331 nm raws li cov tswv cuab ntawm CWDM wavelength kab sib chaws txhais hauv ITU-T G694.2.Nws muaj ib tug duplex LC connector rau optical interface thiab 38-pin connector rau hluav taws xob interface.Txhawm rau txo qhov kev cuam tshuam ntawm optical dispersion nyob rau hauv qhov ntev-ntev, ib hom fiber ntau (SMF) yuav tsum tau siv rau hauv cov qauv no.
Cov khoom lag luam yog tsim los nrog cov qauv tsim, kev sib txuas kho qhov muag / hluav taws xob thiab digital diagnostic interface raws li QSFP Multi-Source Agreement (MSA).Nws tau raug tsim los ua kom tau raws li qhov kev ua haujlwm hnyav tshaj plaws nrog rau qhov kub, av noo thiab EMIinterference.
Lub module ua haujlwm los ntawm ib qho +3.3V fais fab mov thiab LVCMOS / LVTTL thoob ntiaj teb kev tswj cov cim xws li Module Tam Sim No, Pib dua, cuam tshuam thiab Tsawg Fais Fab Hom muaj nyob nrog cov modules.Lub 2-xaim serial interface muaj nyob rau xa thiab tau txais kev tswj cov teeb meem nyuaj thiab kom tau txais cov ntaub ntawv kuaj mob digital.Cov kab ke ntawm tus kheej tuaj yeem hais tau thiab cov channel tsis siv tau tuaj yeem raug kaw kom tsim tau qhov yooj yim tshaj plaws.
Cov khoom no hloov 4-channel 10Gb / s cov ntaub ntawv hluav taws xob nkag rau hauv CWDM optical signals (lub teeb), los ntawm kev tsav 4-wavelength Distributed Feedback Laser (DFB) array.Lub teeb sib xyaw ua ke los ntawm MUX qhov chaw raws li cov ntaub ntawv 40Gb / s, nthuav tawm ntawm lub transmitter module los ntawm SMF.Lub receiver module txais 40Gb/s CWDM optical signals input, thiab de-multiplexes nws mus rau hauv 4 tus neeg 10Gb/s raws nrog sib txawv wavelength.Txhua lub teeb wavelength yog sau los ntawm discrete avalanche photodiode (APD), thiab tom qab ntawd tso tawm raws li cov ntaub ntawv hluav taws xob tom qab amplified thawj zaug los ntawm TIA thiab tom qab ntawd los ntawm cov khoom xa tawm.
CovHUAQ 40 Eyog tsim los nrog cov qauv tsim, kev sib txuas kho qhov muag / hluav taws xob thiab digital diagnostic interface raws li QSFP Multi-Source Agreement (MSA).Nws tau raug tsim los ua kom tau raws li qhov kev ua haujlwm hnyav tshaj plaws nrog rau qhov kub thiab txias, av noo thiab EMI cuam tshuam.Lub module muaj kev ua haujlwm siab heev thiab kev sib koom ua ke, siv tau los ntawm ob-xaim serial interface.
