FAQ

1. Koj puas tuaj yeem muab SFP + rau hauv SFP28 chaw nres nkoj?

A: Yog lawm, tab sis thaum txuas nrog SFP + transceiver, qhov chaw nres nkoj no tsuas tuaj yeem txhawb nqa txog 10Gbps ntawm Internet ceev.

2. QSFP28 thiab SFP28 yog dab tsi?

A: Ob leeg muaj qhov sib txawv thiab cov qauv txheej txheem. Lub SFP28 module tau txhais tias txhawb nqa ib lub tsheb sib kis tus nqi ntawm 25GB, thiab QSFP28 txhawb nqa plaub 25Gbit / s channel nrog tag nrho cov ntaub ntawv tus nqi ntawm 100G

3. Dab tsi ceev yog SFP28 txhawb nqa?

A: SFP 28 optical module muaj qhov sib kis ntawm 25Gbps, siv LC connector.
