FAQ

1. Qhov chaw nres nkoj 25G SFP28 yog dab tsi?

A: D-NET's SFP28 chaw nres nkoj yog rau 25G ceev chaw nres nkoj zoo ib yam li 10G SFP + chaw nres nkoj.

2. Puas yog SFP28 yog Ethernet?

A: Ethernet SFP28 yog rau cov neeg siv khoom siv 25GbE, SFP28 module, raws li daim ntawv pob ntawm SFP +, txhawb nqa 25G Ethernet tus qauv. Rov qab sib raug zoo nrog 10GbE muab txoj hauv kev tsiv teb tsaws chaw rau cov neeg siv khoom xav tau ntau dua bandwidth.
