An SFP28 (Small Form-factor Pluggable 28) transceiver is a compact optical module designed for 32G Fibre Channel (FC) and 25G Ethernet applications. It provides a streamlined upgrade path from 10G networks, delivering higher bandwidth and improved performance. As the standard for high-speed FC deployments and a key building block for 100G Ethernet aggregation, SFP28 is widely used in modern SANs and network scaling. Leading equipment manufacturers like Cisco and Brocade integrate SFP28 ports into their latest switches and directors.

SFP28 vs. SFP+ – key differences
Many network operators compare SFP28 vs. SFP+when considering high-speed networking solutions. While both SFP28 and SFP+ are multi-protocol optical modules supporting Ethernet and Fibre Channel with similar compact sizes, there are key differences:
Feature
SFP28
SFP+
Data rate
Up to 32G FC / 25G Ethernet
Up to 16G FC / 10G Ethernet
Backward compatibility
SFP28 ports support SFP+
N/A
Cost & efficiency
Higher bandwidth efficiency with lower cost per Gbps
Lower power consumption
By upgrading from SFP+ to SFP28, networks can increase speed and efficiency while utilizing existing SFP+ infrastructure in many cases.If it fits your current network setup better, learn more about Smartoptics SFP+ transceivers.
