摘要

Compact, hot-pluggable, and data-agnostic, SFP modules bring up to 4.25 Gbps to a flexible new form factor. The SFP transceiver which is the core device of optical communication is always the research focus in the field of optical communication for both telecommunication and data communication applications. The working principles of SFP including the transmitter components, the receiver components and the microcontroller are discussed in detail. The basic theory of high-speed signal and the concept of high - speed circuit, high-speed board design techniques are presented. A new design of high performance, cost effective SFP transceiver and PCB layout are also presented. The performance of the transceiver is analyzed and the characteristics of the sample are coincident with the expected ones. The status of the transceiver can be monitored and controlled by I2C bus through the interface in real time. This transceiver can meet the requirement of SFF-8472.
