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

OP-QSFP+-01tau tsim los siv rau hauv 40 Gigabit ib ob qhov txuas hla multimode fiber.

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

Qhov chaw xa khoom optical ntawm lub transceiver suav nrog 4-channel VCSEL (Vertical Cavity

(Surface Emitting Laser) array, 4-channel input buffer thiab laser driver, diagnostic monitors, control thiab bias blocks. Rau kev tswj module, lub control interface suav nrog Two Wire Serial interface ntawm lub moos thiab cov ntaub ntawv teeb liab. Diagnostic monitors rau VCSEL bias, module kub, transmitted optical power,Lub zog fais fab optical thiab lub zog fais fab tau txais tau siv thiab cov txiaj ntsig tau txais los ntawm TWS interface. Cov kev ceeb toom thiab cov kev ceeb toom tau tsim rau cov yam ntxwv uas tau saib xyuas. Cov chij tau teeb tsa thiab kev cuam tshuam tsim thaum cov yam ntxwv nyob sab nraum qhov txwv. Cov chij kuj tau teeb tsa thiab kev cuam tshuam tsim rau kev poob ntawm lub teeb liab nkag (LOS) thiab cov xwm txheej txhaum ntawm lub transmitter. Txhua tus chij tau latched thiab yuav tseem teeb tsa txawm tias qhov xwm txheej pib lub latch tshem tawm thiab kev ua haujlwm rov pib dua. Txhua qhov kev cuam tshuam tuaj yeem raug masked thiab cov chij tau pib dua los ntawm kev nyeem cov ntawv sau npe chij tsim nyog. Cov zis optical yuav squelch rau kev poob ntawm lub teeb liab nkag tshwj tsis yog tias squelch raug kaw. Kev kuaj pom qhov txhaum lossis kev kaw channel los ntawm TWS interface yuav kaw channel. Cov xwm txheej, lub tswb ceeb toom / ceeb toom thiab cov ntaub ntawv txhaum muaj nyob ntawm TWS interface.

Qhov chaw txais optical ntawm lub transceiver muaj xws li 4-channel PIN photodiode array, 4-channel TIA array, 4 channel output buffer, diagnostic monitors, thiab control thiab bias blocks. Diagnostic monitors rau optical input power raug siv thiab cov txiaj ntsig muaj los ntawm TWS interface. Lub tswb ceeb toom thiab ceeb toom thresholds tau tsim rau cov yam ntxwv saib xyuas. Cov chij tau teeb tsa thiab interrupts tsim thaum cov yam ntxwv nyob sab nraum thresholds. Cov chij kuj tau teeb tsa thiab interrupts tsim rau kev poob ntawm optical input signal (LOS). Tag nrho cov chij raug latched thiab yuav nyob twj ywm teeb tsa txawm tias qhov xwm txheej pib lub chij tshem tawm thiab kev ua haujlwm rov qab. Tag nrho cov interrupts tuaj yeem masked thiab cov chij raug pib dua thaum nyeem cov chij register tsim nyog. Lub zog tso zis yuav squelch rau kev poob ntawm cov teeb liab input (tshwj tsis yog squelch raug kaw) thiab channel de-activation los ntawm TWS interface. Cov xwm txheej thiab lub tswb ceeb toom / ceeb toom cov ntaub ntawv muaj los ntawm TWS interface.
