Cisco Sib xws 100GBASE-SR4 QSFP28 850nm 100m DOM MPO-12/UPC MMF Optical Transceiver Module, Breakout rau 4 x 25G-SR nrog DDM

OP-QSFP28-01 yog tsim los siv rau hauv 100 Gigabit ib ob qhov txuas hla ntau hom fiber.

Lawv ua raws li QSFP28 MSA thiab IEEE 802.3bm. Lub tshuab xa khoom siv kho qhov muag 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 fais fab, tau txais optical fais fab thiab muab hluav taws xob tau siv thiab cov txiaj ntsig tau 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 lub

cov cwj pwm nyob sab nraum qhov txwv. Cov chij kuj tau teeb tsa thiab kev cuam tshuam tsim rau kev poob ntawm cov teeb liab nkag

(LOS) thiab cov xwm txheej txhaum ntawm lub transmitter. Tag nrho cov chij raug latched thiab yuav tseem teeb tsa txawm tias qhov xwm txheej pib lub latch tshem tawm thiab kev ua haujlwm rov qab los. Txhua qhov kev cuam tshuam tuaj yeem raug masked thiab cov chij raug pib dua los ntawm kev nyeem cov ntawv sau npe chij tsim nyog. Cov zis optical yuav squelch rau kev poob ntawm cov teeb liab nkag tshwj tsis yog tias squelch raug kaw. Kev kuaj pom txhaum lossis kev kaw channel los ntawm TWS interface yuav kaw cov 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 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.
