What is the bandwidth of QSFP?
Knowledge Base + 2024.01.12

The bandwidth of QSFP (Quad Small Form-factor Pluggable) modules can vary depending on the specific type and version. QSFP modules are commonly used in high-speed data communication applications, including Ethernet, InfiniBand, and Fibre Channel. The most common types include QSFP28 (100 Gbps) and QSFP-DD (Double Density) which can support higher data rates such as 200 Gbps or 400 Gbps.

For example:

  • QSFP28 supports a bandwidth of up to 100 Gbps.

  • QSFP-DD can support higher bandwidths like 200 Gbps or 400 Gbps.

It's important to note that the actual bandwidth also depends on the specific implementation and the type of optical or electrical interface being used. Always refer to the specifications provided by the manufacturer for accurate information on the bandwidth of a specific QSFP module.
