Choosing the Right SFP Module for Your Fiber Link

Selecting an SFP module comes down to four questions: what rate does the link need, how far must it reach, which connector and fiber type is available, and does the host device support that module?

Getting these right avoids compatibility surprises and wasted inventory.

• Match rate to the switch uplink speed.
• Use reach ratings with margin.
• Confirm host compatibility before ordering in volume.
