400GBASE-SR4.2 QSFP-DD PAM4 850nm 100m DOM MPO-12/UPC MMF Module-ka Gudbinta Indhaha, Kala-baxa ilaa 4 x 100G-SR1.2
Sharaxaad
+ Module-ka fiilada indhaha ee KCO-QDD-400G-SR4.2-BD waa 400GBASE-SR4 Cisco Compatible QSFP-DD (Quad Small Form-Factor Pluggable – Double Cufnaanta) Transceiver-ka indhaha ee Bi-Direction oo loogu talagalay in lagu shaqeeyo Fiber Multi-Mode (MMF).
+ Module-ka KCO-QDD-400G-SR4.2-BD 400GBASE-SR4.2, isku xirka MTP/MPO-12, ilaa 150m oo ka sarreeya fiilada OM4 OM5 ee is barbar socda.
+ KCO-QDD-400G-SR4.2-BD wuxuu awood u leeyahay inuu taageero isku xirka Ethernet oo gaaraya ilaa 400 Gigabit iyo ilaa afar dherer oo isku xirka jabka Gigabit Ethernet oo gaaraya 100 Gigabit.
+ Module-ka fiilada KCO-QDD-400G-SR4.2-BD waa gudbiye QSFP-DD ah oo loogu talagalay 400G Ethernet, oo badanaa loo isticmaalo xarumaha xogta si loogu xiro isku xiryo cidhiidhi ah oo gaagaaban oo ilaa 100 mitir ah oo ka sarreeya fiilooyinka qaabab badan leh.
+ Adeegsigeeda aasaasiga ah waa jebinta 400G ilaa 4x100G, taasoo u oggolaanaysa dekedda 400G in loo qaybiyo afar dekedood oo 100G ah si loogu xidho server-yo badan ama aaladaha shabakadda. "BD" waxay tilmaamaysaa inay isticmaasho dariiqyo laba geesood ah oo leh laba hirar 50G ah oo ku yaal lammaane fiilooyin is barbar socda, taasoo u baahan module lammaane ah oo leh hirar dherer oo dhammaystiran si loo dhammaystiro isku xirka.
+ Waa mid u hoggaansan hab-maamuuska IEEE 802.3 iyo heerka 400GAUI-8/PAM4.
+ La socodka ogaanshaha dhijitaalka ah ee ku dhex jira (DDM) wuxuu kuu oggolaanayaa inaad gasho xuduudaha hawlgalka waqtiga-dhabta ah. Waxay ku habboon tahay codsiyada isku xirka ethernet-ka 400G iyo xarunta xogta.
+ Waxay taageeri kartaa 4× 100G-SR1.2.
+ Iswaafajintu waa la xaqiijiyay Arista/NVIDIA/Cisco RoCE Networking.

Faa'iidada
+Xalalka Isku xirka:Isku xirka 400G-ilaa-400G ee loogu talagalay Beddelka-U-Beddelka, 400G-ilaa-afar Xiriir 100G ah ee Beddelka-U-Beddelka
+Waxqabadka iyo Tayada Hoggaaminta ee 100G: Iyada oo leh Broadcom Chip oo ku dhex jira oo lagu qalabeeyay baakad BOX ah oo si gaar ah loogu talagalay, gudbiyaha QSFP28 wuxuu bixiyaa xawaare sare iyo awood hoose oo ku jirta isku xirka 100G.
+Waxaa lagu tijaabiyay aaladaha martigeliyaha si loo helo is-dhexgal la xaqiijiyay: Cutub kasta waxaa lagu tijaabiyaa tayada si loo hubiyo iswaafajinta jawiga beddelka ee la beegsanayo, kaas oo dammaanad qaadaya hawlgallada aan cillad lahayn.
+Ku shaqee isku xirka aan kala go 'lahayn ee shabakadaada:Dib-u-habaynta gudbiyaha si uu ula shaqeeyo noocyo kala duwan.
