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.

Setting and Installation
2.1 Setting the SQE Switch
When this transceiver is connected directly to a
repeater, the SQE function must be disabled.
Note that a 10Base-T concentrator is a repeater
unit.
SQE Test:
§
§
Default: enable
Enable: attaching the transceiver to a LAN
card in a computer, or to device expecting
the SQE test signal such as bridge or router
§
Disable: attaching the transceiver to
a
hub’ s or repeater’ s AUI port

2.2 Installation
Because of the ET-118 compact design, it is
not necessary to connect it to another Ethernet
device via transceiver cable.
The ET-118 15-pin male connector is plugged
into the 15-pin female AUI connector on a
coax Ethernet board or other Ethernet device,
such as a repeater. Once attached, make sure
that the slide locks are properly latched. The
other end of the ET-118 features two female ST
connectors, one for transmit data and one for
receive data. These make with two male ST
connectors at one end of a duplex fiber optic
cable segment, as showing figure 2-1 and
figure 2-2.
