40KM 40G QSFP + Optical Transceiver Module
LubHUAQ40Eyog ib lub transceiver module tsim rau 40Km optical kev sib txuas lus daim ntawv thov. 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 hluav taws xob cov ntaub ntawv rau 4 CWDM optical teeb liab, thiab multiplexes lawv rau hauv ib qho channel rau 40Gb / s optical kis tau tus mob. Reversely, ntawm sab receiver, lub module optically de-multiplexes 40Gb / s input rau hauv 4 CWDM channels teeb liab, thiab hloov lawv mus rau 4 channel tso zis hluav taws xob cov ntaub ntawv.
Cov wavelengths nruab nrab ntawm 4 CWDM channels yog 1271, 1291, 1311 thiab 1331 nm ua cov tswv cuab ntawm CWDM wavelength grid txhais hauv ITU-T G694.2. Nws muaj ib lub duplex LC connector rau lub optical interface thiab ib lub 38-pin connector rau lub electrical interface. Txhawm rau kom txo qhov optical dispersion hauv lub system ntev, ib hom fiber (SMF) yuav tsum tau siv rau hauv lub module no.
Cov khoom no tau tsim los nrog cov qauv zoo li cas, kev sib txuas optical/electrical thiab digital diagnostic interface raws li QSFP Multi-Source Agreement (MSA). Nws tau tsim los kom ua tau raws li qhov xwm txheej sab nraud hnyav tshaj plaws suav nrog qhov kub thiab txias, av noo thiab EMIinterference.
Lub module ua haujlwm los ntawm ib lub zog fais fab +3.3V thiab LVCMOS/LVTTL cov teeb liab tswj thoob ntiaj teb xws li Module Present, Reset, Interrupt thiab Low Power Mode muaj nrog cov modules. Muaj 2-wire serial interface los xa thiab txais cov teeb liab tswj nyuaj dua thiab kom tau txais cov ntaub ntawv kuaj mob digital. Cov channel ib leeg tuaj yeem raug hais txog thiab cov channel tsis siv tuaj yeem raug kaw rau qhov yooj yim tsim qauv siab tshaj plaws.
Cov khoom no hloov cov ntaub ntawv hluav taws xob 4-channel 10Gb/s mus rau hauv CWDM optical signals (teeb), los ntawm kev tsav 4-wavelength Distributed Feedback Laser (DFB) array. Lub teeb raug sib xyaw los ntawm MUX qhov chaw ua 40Gb/s cov ntaub ntawv, kis 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 kheej 10Gb/s channels nrog wavelength sib txawv. Txhua lub teeb wavelength yog sau los ntawm discrete avalanche photodiode (APD), thiab tom qab ntawd tso tawm ua cov ntaub ntawv hluav taws xob tom qab amplified thawj zaug los ntawm TIA thiab tom qab ntawd los ntawm post amplifier.
LubHUAQ40Eyog tsim los nrog daim ntawv qhia, kev sib txuas optical/hluav taws xob thiab digital diagnostic interface raws li QSFP Multi-Source Agreement (MSA). Nws tau tsim los ua kom tau raws li qhov xwm txheej sab nraud hnyav tshaj plaws suav nrog qhov kub thiab txias, av noo thiab EMI cuam tshuam. Lub module muaj kev ua haujlwm siab heev thiab kev koom ua ke ntawm cov yam ntxwv, nkag tau los ntawm ob-xaim serial interface.
