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

OP-QSFP28-01 adapangidwa kuti azigwiritsidwa ntchito mu 100 Gigabit pa sekondi imodzi pama fiber ambiri.

Amagwirizana ndi QSFP28 MSA ndi IEEE 802.3bm. Gawo la optical transmitter la transceiver limaphatikizapo 4-channel VCSEL (Vertical Cavity Surface Emitting Laser) gulu, 4-channel input buffer ndi laser driver, monitors monitors, control and bias blocks. Kuti muwongolere ma module, mawonekedwe owongolera amaphatikiza mawonekedwe a Two Wire Serial a wotchi ndi ma sign a data. Oyang'anira matenda a

Kukondera kwa VCSEL, kutentha kwa module, mphamvu yamagetsi yopatsirana, kulandila mphamvu yamagetsi ndi magetsi operekera kumayendetsedwa ndipo zotsatira zimapezeka kudzera mu mawonekedwe a TWS. Ma alarm ndi machenjezo amakhazikitsidwa pazoyang'aniridwa. Mbendera zimayikidwa ndipo zosokoneza zimapangidwa pamene

makhalidwe ali kunja kwa malire. Mbendera zimayikidwanso ndipo zosokoneza zimapangidwira kutayika kwa chizindikiro

(LOS) ndi zolakwika za transmitter. Mbendera zonse zimakhomeredwa ndipo zizikhalabe zokhazikika ngakhale zomwe zidayambitsa latch zichotsedwa ndikuyambiranso. Zosokoneza zonse zitha kubisika ndipo mbendera zimakonzedwanso powerenga zolembera zoyenera. Kutulutsa kwa kuwala kumayimitsa kutayika kwa siginecha yolowera pokhapokha ngati squelch yayimitsidwa. Kuzindikira zolakwika kapena kuyimitsa njira kudzera mu mawonekedwe a TWS kuzimitsa kanjira. Mkhalidwe, chenjezo / chenjezo ndi zolakwika zilipo kudzera pa mawonekedwe a TWS.

Gawo la optical receiver la transceiver limaphatikizapo 4-channel PIN photodiode array, 4-channel TIA array, 4 channels output buffer, diagnostic monitors, ndi control and bias blocks. Zowunikira zowunikira mphamvu zamagetsi zamagetsi zimayendetsedwa ndipo zotsatira zimapezeka kudzera mu mawonekedwe a TWS. Ma alarm ndi machenjezo amakhazikitsidwa pazoyang'aniridwa. Mbendera zimayikidwa ndipo zosokoneza zimapangidwa pamene mawonekedwe ali kunja kwa malire. Mbendera zimayikidwanso ndikusokoneza zomwe zimapangidwira kutaya chizindikiro cha optical input (LOS). Mbendera zonse zimakhomeredwa ndipo zizikhalabe zokhazikitsidwa ngakhale zomwe zikuyambitsa mbendera zichotsedwa ndikuyambiranso. Zosokoneza zonse zitha kubisika ndipo mbendera zimayikidwanso mukawerenga zolembera zoyenera. Kutulutsa kwamagetsi kumakankhira kutayika kwa siginecha yolowera (pokhapokha ngati squelch yazimitsidwa) ndikuyimitsa kanjira kudzera pa mawonekedwe a TWS. Zambiri ndi alamu / chenjezo zimapezeka kudzera pa mawonekedwe a TWS.
