Boleng bo botle 10g Sfp+ Ho Sfp+ Active Optical Cable - 25G SFP28 Direct Attach Cable (DAC) JHA-SFP28-25G-PCU - JHA Detail:
Tlhaloso e Akaretsang
SFP28 Direct Attach Cables li lumellana le litlhaloso tsa SFF-8432 le SFF-8402. Likhetho tse fapaneng tsa litekanyo tsa mohala li fumaneha ho tloha ho 30 ho isa ho 26 AWG ka likhetho tse fapaneng tsa bolelele ba cable (ho fihla ho 5m).
Likopano tsa SFP28 passive cable ke ts'ebetso e phahameng, litharollo tsa I / O tse theko e boima bakeng sa 25G Ethernet. Lithapo tsa koporo tsa SFP28 li lumella lihlahisoa tsa hardware ho fihlela sekhahla se phahameng sa boema-kepe, ho hlophisoa le ho sebelisoa ka theko e tlase haholo le tekanyetso e fokotsehileng ea matla.
