Small Form-Factor Pluggable Plus (SFP+)

An enhanced SFP module supporting 10 Gbps, physically compatible with SFP ports.

Definition

SFP+ is the most common 10G form factor for fiber optics and DAC cables. Many SFP+ ports also accept 1G SFP modules, but SFP ports cannot run SFP+ modules at 10G. SFP28 uses the same form factor at 25 Gbps.

Example

A server's 10G NIC uses an SFP+ 10GBASE-SR module.

Exam tip

Same physical size as SFP, but SFP+ means 10G.
