Ifektri ekumgangatho ophezulu 25G SFP28 Passive Direct Qhoboshela iCable yeCopper Twinax

Iindibano ze-cable ze-SFP28 ze-passive zisebenza ngokuphezulu, i-I / O ye-I / O isisombululo esinexabiso le-25G Ethernet.Iintambo zobhedu ze-SFP28 zivumela abavelisi be-hardware ukuba bafezekise ukuxinana kwezibuko eliphezulu, ukulungelelaniswa kunye nokusetyenziswa ngexabiso eliphantsi kakhulu kunye nokunciphisa uhlahlo lwabiwo-mali lwamandla.

I-SFP28 i-Direct Attach Cables iyahambelana ne-SFF-8432 kunye ne-SFF-8402 ingcaciso.Iinketho ezahlukeneyo zegeyiji yocingo ziyafumaneka ukusuka kwi-30 ukuya kwi-26 AWG kunye nokukhetha okuhlukeneyo kobude bentambo (ukuya kuthi ga kwi-5m).

Iimbonakalo 

Ukuya kuthi ga kwi-25.78125 Gbps izinga ledatha

Ukuya kuthi ga kwi-5 yeemitha zokuhanjiswa

I-SFP 20PIN efakwe kwi-Hot-pluggable footprint
