The block diagram shows two different SFP+ module implementations, one based on
linear and one based on limiting receiver
linear and one based on limiting receiver
SFP+ Module
The SFP+ transceiver (Figure 5) is an evolution of the SFP optic developed for 1-Gbps Ethernet and 1-Gbps, 2-Gbps
and 4-Gbps Fibre Channel. It extends the data rate up to 11.10 Gbps while meeting low power and low
electromagnetic interference (EMI) requirements for datacom and storage applications.
Similar to SFP, the SFP+ module is a bidirectional device with a transmitter and receiver in the same physical
package. It has a 20-pin connector on the electrical interface and a duplex LC connector on the optical interface.

Figure 6 shows an SFP+ transceiver module functional block diagram. It contains two parts: the transmitter and the
receiver.
A possible SFP+ module functional block diagram is shown in. It contains three parts: a (A) Transmitter, (B)
Receiver, and (C) I2C Management interface. This architecture does not exclude other possible implementations
that can be compliant to the SFP+ specs (such as CDR-based designs).
