Kev piav qhia
+ Cisco QSFP-100G-SR4-S Compatible QSFP28 Optical Transceiver Module yog tsim los siv hauv 100GBASE Ethernet throughput mus txog 100m tshaj OM4 multimode fiber (MMF) siv lub wavelength ntawm 850nm ntawm MTP / MPO-12 connector. Qhov transceiver no ua raws li IEEE 802.3bm 100GBASE-SR4 thiab CAUI-4 tus qauv. Digital diagnostics functions kuj muaj nyob ntawm I2C interface, raws li tau teev tseg los ntawm QSFP28 MSA, tso cai rau kev nkag mus rau lub sijhawm ua haujlwm tsis ua haujlwm. Nrog rau cov yam ntxwv no, qhov no yooj yim rau nruab, kub swappable transceiver yog tsim los siv rau hauv ntau daim ntawv thov, xws li cov chaw zov me nyuam, kev ua haujlwm siab hauv kev sib txuas, kev lag luam tseem ceeb thiab kev faib txheej txheej.

Kev piav qhia dav dav
OP-QSFP28-01 yog tsim los siv nyob rau hauv 100 Gigabit ib ob txuas ntawm ntau hom fiber ntau.
Lawv ua raws li QSFP28 MSA thiab IEEE 802.3bm. Cov 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 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 kev tsis ncaj ncees, qhov ntsuas kub, qhov hluav taws xob xa hluav taws xob, 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. Chij yog teem thiab cuam tshuam generated thaum lub
tus cwj pwm nyob sab nraum qhov pib. Cov chij tseem raug teeb tsa thiab cuam tshuam tsim rau qhov poob ntawm cov teeb liab tawm tswv yim
(LOS) thiab xa cov teeb meem txhaum cai. 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 muaj, 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.
