KCO QSFP + 40G SR4 40Gb/s QSFP + MMF 100M MPO Transceiver nrog DDM

OP-QSFP+-01yog tsim los siv nyob rau hauv 40 Gigabit ib ob txuas ntawm multimode fiber ntau.

Lawv ua raws li QSFP + MSA thiab IEEE 802.3ba 40GBASE-SR4.

Qhov kho qhov muag transmitter feem ntawm lub transceiver suav nrog 4-channel VCSEL (Vertical Cavity

Surface Emitting Laser) array, 4-channel input tsis thiab laser tsav tsheb, kuaj xyuas, tswj thiab kev tsis ncaj ncees blocks. Rau kev tswj hwm module, tus tswj interface suav nrog Ob Lub Hlau Serial interface ntawm moos thiab cov ntaub ntawv teeb liab. Diagnostic monitors rau VCSEL bias, module kub, kis tau tus mob optical zog,tau txais lub zog kho qhov muag thiab cov khoom siv hluav taws xob tau siv thiab cov txiaj ntsig tau muaj los ntawm TWS interface. Lub tswb thiab ceeb toom qhov pib raug tsim los rau cov yam ntxwv saib xyuas. Cov chij tau teeb tsa thiab cuam tshuam tsim tawm thaum cov cwj pwm nyob sab nraud ntawm qhov pib. Cov chij tseem raug teeb tsa thiab cuam tshuam tsim tawm rau qhov poob ntawm cov teeb liab tawm tswv yim (LOS) thiab cov teeb meem tsis raug xa mus. Txhua tus chij tau latched thiab yuav nyob twj ywm txawm tias qhov xwm txheej pib lub latch clears thiab rov ua haujlwm. Tag nrho cov kev cuam tshuam tuaj yeem npog tau thiab cov chij tau rov pib dua los ntawm kev nyeem cov npe chij tsim nyog. Lub optical tso zis yuav squelch rau poob ntawm input teeb liab tshwj tsis yog tias squelch yog neeg xiam. Kev kuaj pom tsis raug lossis kev tsis ua haujlwm channel los ntawm TWS interface yuav lov tes taw cov channel. Cov xwm txheej, ceeb toom / ceeb toom thiab cov ntaub ntawv tsis raug muaj nyob ntawm TWS interface.

Qhov chaw txais khoom kho qhov muag ntawm lub transceiver suav nrog 4-channel PIN photodiode array, 4-channel TIA array, 4 channel tso zis tsis tawm, kuaj xyuas, thiab tswj thiab kev tsis ncaj ncees blocks. Diagnostic monitors rau optical input power yog siv thiab cov txiaj ntsig muaj nyob hauv TWS interface. Lub tswb thiab ceeb toom qhov pib raug tsim los rau cov yam ntxwv saib xyuas. Cov chij tau teeb tsa thiab cuam tshuam tsim tawm thaum cov cwj pwm nyob sab nraud ntawm qhov pib. Cov chij tseem raug teeb tsa thiab cuam tshuam los ntawm kev poob ntawm qhov muag pom teeb liab (LOS). Tag nrho cov chij tau latched thiab yuav nyob twj ywm txawm tias qhov xwm txheej pib tus chij tshem tawm thiab rov pib ua haujlwm. Txhua qhov kev cuam tshuam tuaj yeem npog tau thiab cov chij tau rov pib dua thaum nyeem cov npe chij tsim nyog. Cov zis hluav taws xob yuav squelch rau poob ntawm cov teeb liab tawm tswv yim (tshwj tsis yog squelch yog neeg xiam) thiab channel de-activated los ntawm TWS interface. Cov xwm txheej thiab ceeb toom / ceeb toom cov ntaub ntawv muaj nyob ntawm TWS interface.
