The pluggable Transceivers is one of the main network components in the modern data center, based on the data rate structured cabling topology, different form factors transceivers like SFP, SFP+, XFP, QSFP+ SFP28, SFP56, CFP, CFP2, CFP4, QSFP28, QSFP56, QSFP-DD may be used.
The flowing list is about how to choose transceivers intra racks, inter racks, and for long span/inter buildings.
