Kaihanga mo te 4k Fiber Optic Cable Mo te Rongorau - 25G SFP28 Direct Attach Cable (DAC) JHA-SFP28-25G-PCU - JHA
Kaihanga mo te 4k Fiber Optic Cable For Multimedia - 25G SFP28 Direct Attach Cable (DAC) JHA-SFP28-25G-PCU – JHA Taipitopito:
Whakaahuatanga Whanui
SFP28 Direct Attach Cables e whai ana ki nga whakaritenga SFF-8432 me SFF-8402. He maha nga whiringa mo te ine waea mai i te 30 ki te 26 AWG me nga momo whiringa mo te roa o te taura (tae atu ki te 5m).
Ko nga huinga taura wahangu SFP28 he tino mahi, he utu pai nga otinga I/O mo te 25G Ethernet. Ka taea e nga taura parahi SFP28 te hanga taputapu ki te whakatutuki i te kiato tauranga teitei, te whirihora me te whakamahi i te utu iti rawa me te iti o te tahua hiko.
