1. SFP28 is an enhanced version of SFP+. It has the same size as SFP+, but it can support single channel 25Gb/s rate. SFP28 provides an efficient solution for 10G-25G-100G network upgrades to meet the growing needs of next-generation data center networks.
2, QSFP+ package can support four channels at the same time, each channel data rate of 10Gbit/s, through the four channels to achieve 40Gbps transmission rate. Compared with SFP+, the transmission rate of the QSFP+ optical module can be up to four times that of the SFP+ optical module. The QSFP+ optical module can be directly used when a 40 GBIT/s network is deployed, effectively saving costs and improving port density.
3. SFP28 is the encapsulation type of the 25 GBIT/s /32 GBIT/s optical module. QSFP+ is an encapsulation type of the 40 GBIT/s or 56 gbit/s optical module. SFP28 has a single laser and a single detector; The QSFP+ built-in 4-channel laser array and 4-channel detector array encapsulation type of the interface protocol are different
4. Conclusion: The two can not be connected successfully
