General Descriptions

1.1 Introduction

The fiber Optic Medium Attachment Unit provides the complete Attachment Unit Interface (AUI) to fiber optic interface. It connects to any standard IEEE802.3 Data Terminal Equipment AUI connector, and requires no configuration. It is connected through a standard AUI cable or direct connection to an Ethernet board or Ethernet device unit via the AUI port. The MAU includes the complete transmission, receiving, and collision detection, jabber timer, link test function as specified by the IEEE802.3 for use in a 10Mbps CSMA/CD Ethernet on a duplex fiber optic LAN system.

♦Complies with the IEEE802.3 10Base-FL standards.

♦Supports up to 2000meters of duplex fiber optic cable segment.

1.2 Features

♦Compact design allows direct connection to an Ethernet board of Ethernet device unit via the AUI port.

♦Two female ST connectors, one for transmitting data and the other is for receiving data.

♦Link-integrity test for the automatic checking of fiber lines

♦Provides LEDs for a quick visual check of individual link status, collision, Transmit, and receive.

♦Selectable end-of-packet SQE test
