The reference design as shown is a small form-factor pluggable (SFP) transceiver evaluation board. This design provides designers convenient way for evaluating SFP fiber-optic transceivers as well as SFP multisource agreement (MSA). The SFP transceivers have a wide range of detachable interfaces to multimode/single-mode fiber optics, which allows users to select the appropriate transceiver according to the required optical range for the network. The SFP interfaces between communication devices like switches, routers and fiber optic cables, and performs conversions between optical and electrical signals.

The TE connectivity amp 1367073-1 is specifically used in this design. The TE connectivity (TE) SFP+ product family extends the use of the Small Form-Factor Pluggable (SFP) interconnect up to 10 Gbps. This system meets the performance requirements of SFF (Small Form-Factor) specification SFF-8431 and supports 8G fiber channel, 10G ethernet, infiniBand standard and Fibre Channel over Ethernet (FCoE) applications. The design allows for serial data transmission up to 10Gbps in each direction. The mechanical design of the cable braid crimp and EMI skirt suppress EMI radiation. The low power consumption makes the SFP+ copper cable assembly an economical solution for within rack or rack-to-rack applications. Both passive and active copper cable assemblies are available. The active cable assembly design has signal amplification and equalization in the assembly. The active copper assemblies are typically used in host systems that do not employ EDC. The active SFP+ cable assemblies also incorporate Rx LOS and Tx disable features. As with passive cables, the industry standard EEPROM signature enables the host system to differentiate between an active copper cable and a fiber optic module.

The SFP is used in network interfaces like switches and routers. The SFP transceivers are designed to support SONET, gigabit ethernet, fibre channel, and other forms of data communications.
