What are the differences in specifications and capabilities between SFP and QSFP transceivers?
QSFP28 is the next iteration of QSFP+, however, it keeps the same form factor and QSFP28 ports accept QSFP+ transceivers as well. So, what makes QSFP28 different and what are its main features and capabilities?
Quad small form-factor pluggable, or QSFP, is an evolution of SFP. While QSFP optics are similar to SFP in many ways, there are wide distinctions in form and data rates.
SFP28 is an upgraded version of SFP+ , and SFP28 ports in network equipment are compatible with both SFP and SFP+ transceivers. However, what are the main features and capabilities of an SFP28 transceiver?
