Connectors & Cables
AUI connection
: D-sub 15 pin male connector
AUI drop cable (50 meters max.)
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:

Ethernet Fiber Optic Transceiver
Model: KT-10F v2
DOC.G990126-KT10F-V2-K
P/N: 750-0125-001
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 attached to the AUI connector of an
Ethernet device via standard AUI cable.
Fiber connection:
ST connectors
Fiber optic cable
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:
Fiber mode: multimode
Wavelength: 850

The transceiver can operate with a variety of fiber optic
sizes, for example, 50/125
µ
m, 62.5/125
µ
m, and 100/140
µ
m.
Setting Switches
There are two switches which are accessible on the side of
the transceiver enclosure. The functions of these switches
are:
SW#
Setting
Function
SW1
On
Enable SQE test (factory default)
Off
Disable SQE test (for repeater device)
SW2
On
Full-duplex mode
Off
Half-duplex mode (factory default)
Important:
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.
