2019 Tayada sare leh Sfp28-25g-Aoc 5m - 25G SFP28 Si toos ah Cable-ka Ku Xidhan (DAC) JHA-SFP28-25G-PCU – JHA Faahfaahinta:

Sharaxaada Guud

Xargaha tooska ah ee SFP28 waxay waafaqsan yihiin shuruudaha SFF-8432 iyo SFF-8402. Doorashooyinka kala duwan ee cabbirka siliga ayaa laga heli karaa 30 ilaa 26 AWG oo leh xulashooyin kala duwan oo dhererka fiilada ah (ilaa 5m).

Isku xirka xargaha daahsoon ee SFP28 waa wax qabad sare, qiime wax ku ool ah I/O xalalka 25G Ethernet. Xadhkaha naxaasta ah ee SFP28 ayaa u oggolaanaya soosaarista qalabka si ay u gaadhaan cufnaanta dekeda sare, habaynta iyo ka faa'iidaysiga qiime aad u jaban iyo miisaaniyad koronto oo yar.
