100G QSFP28/4SFP28 Taura Whakauru Tika JHA-QSFP28-4SFP28-100G-PCU
Whakaahuatanga Whanui
Ko te QSFP28 te huihuinga taura parahi e waru nga takirua parahi rereke, e whakarato ana i nga waahana whakawhiti raraunga e wha i te tere ki te 28Gbps mo ia hongere, ka tutuki i te 100G Ethernet, 25G Ethernet me te InfiniBand Enhanced Rate Raraunga (EDR) whakaritenga. mai i te 26AWG ki te 30AWG-ko tenei huihuinga taura parahi 100G he iti te mate whakaurunga me te iti o te korero whakawhiti.
I hoahoatia mo nga tono i roto i te pokapu raraunga, nga maakete whatunga me nga waea waea e hiahia ana kia tere tere, kia pono te huihuinga taura, ko tenei reanga hua e whai ake nei he rite te atanga whakahiato me te QSFP + ahua tauwehe, kia pai ai te whakamuri ki nga tauranga QSFP o naianei. Ka taea te whakamahi me te QSFP28 Ko nga tono 10G me te 14G o naianei me te tohu tohu tapatahi.
