Fiber connection: ST connectors
Fiber optic cable
Features
• Complies with IEEE 802.3 10Base-FL standard.
• A complete interface of the AUI to fiber optic cable link.
• Flexible selection for half-duplex or full-duplex mode
• Supports data transfer rate up to 20Mbps for full-duplex
• Capability for driving the fiber optic cable segment up
to 2000M (6560 ft.).
Two ST style connectors are provided for connection to
fiber optic cable. One is for transmitting and the other is
for receiving. See the following figure:

AUI connection: D-sub 15 pin male connector
AUI drop cable (50 meters max.)
Setting Switches
There are two switches which are accessible on the side of
the transceiver enclosure. The functions of these switches
are:
The AUI connector is used for attaching the transceiver to
the AUI port provided by an Ethernet device such as an
Ethernet MAC controller, an Ethernet repeater, or an
Ethernet concentrator via an AUI drop cable. The pin
assignments are shown as below:
General Description
The KT-10F Ethernet transceiver complies with IEEE 802.3
transceiver specifications and 10Mbps Ethernet CSMA/
CD operation to extend the your existing Ethernet segment
up to 2000 meters by using fiber optic cable.

The transceiver is shipped from the factory with the SQE
test enabled. If the transceiver is connected to an Ethernet
repeater, a 10Base-T hub, or a wiring concentrator, the SQE
test function should be disabled.
