25G SFP28 Direct Attach Cable (DAC) JHA-SFP28-25G-PCU

Kufotokozera Kwachidule:

SFP28 Direct Attach Cables imagwirizana ndi SFF-8432 ndi SFF-8402.Zosankha zosiyanasiyana zamawaya gauge zimapezeka kuchokera ku 30 mpaka 26 AWG ndi zosankha zosiyanasiyana za kutalika kwa chingwe (mpaka 5m).

Kufotokozera Kwambiri

Misonkhano ya SFP28 passive cable ndi ntchito yapamwamba, yotsika mtengo I / O zothetsera 25G Ethernet.Zingwe zamkuwa za SFP28 zimalola opanga ma hardware kuti akwaniritse kuchuluka kwa madoko, kusinthika ndi kugwiritsidwa ntchito pamtengo wotsika kwambiri komanso kuchepetsedwa kwa bajeti yamagetsi.

Mawonekedwe

◊ Kufikira ku 25.78125 Gbps kuchuluka kwa data

◊ Kutumiza mpaka 5 mita
