Cisco Yogwirizana ndi 100GBASE-SR4 QSFP28 850nm 100m DOM MPO-12/UPC MMF Optical Transceiver Module, Yofalikira mpaka 4 x 25G-SR yokhala ndi DDM

OP-QSFP28-01 yapangidwa kuti igwiritsidwe ntchito mu ma Gigabit 100 pa sekondi iliyonse kudzera pa ulusi wa multimode.

Zimagwirizana ndi QSFP28 MSA ndi IEEE 802.3bm. Gawo la transmitter la transceiver limaphatikizapo gulu la VCSEL (Vertical Cavity Surface Emitting Laser) la njira 4, buffer yolowera ya njira 4 ndi driver wa laser, ma diagnostic monitors, ma control ndi bias blocks. Pakuwongolera module, mawonekedwe owongolera amaphatikizapo mawonekedwe awiri a Two Wire Serial a clock ndi data signals. Ma diagnostic monitors a

Kusankhana kwa VCSEL, kutentha kwa module, mphamvu yowunikira yotumizidwa, mphamvu yowunikira yolandiridwa ndi magetsi operekera magetsi zimayikidwa ndipo zotsatira zake zimapezeka kudzera mu mawonekedwe a TWS. Malire a alamu ndi chenjezo amakhazikitsidwa pazinthu zoyang'aniridwa. Mbendera zimayikidwa ndipo zosokoneza zimapangidwa pamene

makhalidwe ali kunja kwa malire. Mbendera zimayikidwanso ndipo zosokoneza zimapangidwa chifukwa cha kutayika kwa chizindikiro cholowera

(LOS) ndi mikhalidwe ya cholakwika cha transmitter. Mbendera zonse zimamangiriridwa ndipo zidzakhazikikabe ngakhale vuto lomwe limayambitsa latch litachotsedwa ndipo ntchitoyo iyambiranso. Zosokoneza zonse zitha kubisika ndipo mbendera zimabwezeretsedwanso powerenga register yoyenera ya mbendera. Chotulutsa cha kuwala chidzachepetsa chizindikiro cholowera pokhapokha ngati squelch yazimitsidwa. Kuzindikira cholakwika kapena kuzimitsa njira kudzera mu mawonekedwe a TWS kudzaletsa njirayo. Zambiri za momwe zinthu zilili, alamu/chenjezo ndi zolakwika zimapezeka kudzera mu mawonekedwe a TWS.

Gawo la optical receiver la transceiver limaphatikizapo 4-channel PIN photodiode array, 4-channel TIA array, 4 channel output buffer, diagnostic monitors, ndi control and bias blocks. Diagnostic monitors for optical input power limagwiritsidwa ntchito ndipo zotsatira zimapezeka kudzera mu TWS interface. Alarm and warning thresholds are stooked at the monitoring attributes. Flags are settings and interrupts as features as well been output. Flags are settings and interrupts are been output output. Flags are settings and interrupts are been output output as signal (LOS) ikakhala kunja kwa malire. Flags are also settings and interrupts are been settings ngakhale vuto lomwe limayambitsa mbendera litatha ndipo ntchito iyambanso. Interrupts zonse zitha kubisika ndipo flags zimayambanso kukonzedwanso akawerenga flag register yoyenera. Mphamvu zamagetsi zidzachepa chifukwa cha kutayika kwa chizindikiro cholowera (pokhapokha ngati squelch yazimitsidwa) ndi channel de-activation kudzera mu TWS interface. Status and alarm/chenjezo zambiri zimapezeka kudzera mu TWS interface.
