SIC-1FEA

Introduction

1-port 10Base-T/100Base-TX Ethernet interface module (SIC-1FEA), in which FE stands for Fast Ethernet

and A is used to differentiate SIC-1FEA from the 1FE module. SIC-1FEA is used to implement the

communication between Routers and LANs. It supports:

• Effective transmission distance of 100 meters with category-5 twisted pair cables

• Operating speeds of both 100 Mbps and 10 Mbps and autosensing

• Both full duplex (in common use) and half-duplex operating modes
