Hoobkas siab zoo 25G SFP28 Passive Direct Txuas Copper Twinax Cable

SFP28 passive cable sib dhos yog qhov ua tau zoo, raug nqi I / O cov kev daws teeb meem rau 25G Ethernet.SFP28 tooj liab cables tso cai rau cov khoom siv kho vajtse kom ua tiav qhov chaw nres nkoj siab, kev teeb tsa thiab kev siv ntawm tus nqi qis heev thiab txo nqi zog.

SFP28 Direct Attach Cables tau ua raws li SFF-8432 thiab SFF-8402 specifications.Ntau yam kev xaiv ntawm cov xov hlau ntsuas muaj nyob ntawm 30 txog 26 AWG nrog ntau txoj kev xaiv ntawm cable ntev (txog 5m).
