SFP+ Module(Small Form-factor Pluggable Plus Module) is an enhanced version of the SFP that supports applications for 8Gbps Fiber Channel, 10Gbps Gigabit Ethernet and Optical Transport Network standard OTU2. It is a popular industry format supported by many network component vendors. SFP+ uses the same space-per-port as standard SFP but leaves more circuitry to be implemented on the host board instead of inside the module. SFP+ module can be divided into limiting or linear type according to the functionality of the inbuilt electronics. Limiting SFP+ module includes the signal amplifier to re-shape the received signals whereas linear one does not. Linear module is mainly used with the low bandwidth standard such as 10GBASE-LRM; otherwise, limiting modules are preferred.
