Fekitari yepamusoro mhando 25G SFP28 Passive Direct Attach Copper Twinax Cable

Iyo SFP28 passive cable assemblies ndeyekuita kwepamusoro, inodhura I / O mhinduro dze25G Ethernet.SFP28 tambo dzemhangura dzinobvumira hardware inogadzira kuti iwane yakakwirira chiteshi density, configurability uye kushandiswa nemutengo wakaderera kwazvo uye kuderedzwa kwemagetsi bhajeti.

SFP28 Direct Attach Cables inoenderana neSFF-8432 uye SFF-8402 zvakatemwa.Sarudzo dzakasiyana dzewaya geji dzinowanikwa kubva pa30 kusvika 26 AWG nesarudzo dzakasiyana dzehurefu hwetambo (kusvika pa5m).
