Three Types of Ethernet SFP Transceiver Modules Introduction

In the market, there are a range of Ethernet SFP transceiver module s, including Fast Ethernet (FE) SFP, Gigabit Ethernet (GE) SFP and 10 Gigabit Ethernet (10GbE) SFP Plus (SFP+). These small, modular optical interface transceivers offer a convenient and cost effective solution for the adoption of GE and FC in data center, campus, metropolitan area access and ring networks, and storage area networks.

The SFP transceivers are high performance, cost effective modules supporting dual data-rate of 155Mbps and 2km transmission distance with MMF. The transceiver consists of three sections: a FP laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements. The transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472.
