25G SFP28 Uaea Fa'apipi'i Sa'o (DAC) JHA-SFP28-25G-PCU
Fa'amatalaga Lautele
SFP28 Direct Attach Cables e ogatasi ma fa'amatalaga SFF-8432 ma SFF-8402.O filifiliga eseese o fua uaea e maua mai le 30 i le 26 AWG ma filifiliga eseese ole umi ole uaea (e o'o ile 5m).
Ole SFP28 passive cable assemblies e maualuga le faʻatinoga, tau aoga I / O fofo mo 25G Ethernet.SFP28 uaea apamemea e mafai ai e le gaosiga o meafaigaluega ona ausia le maualuga o le taulaga, fetuutuunai ma le faʻaogaina i se tau maualalo ma faʻaititia le paketi o le eletise.
