Installation Guide
Ethernet Fiber Optic Transceiver
Model:KT-10Fv2
DOC.G990126-KT10F-V2-K
P/N: 750-0125-001
General Description
The KT-10F Ethernet transceiver complies with IEEE 802.3
transceiver speci ications and 10Mbps Ethernet CSMA/
CD operation to extend the your existing Ethernet segment
up to 2000 meters by using iber optic cable.
The transceiver is attached to the AUI connector o an
Ethernet device via standard AUI cable.
Fiber connection: ST connectors
Fiber optic cable
Two ST style connectors are provided or connection to
iber optic cable. One is or transmitting and the other is
or receiving. See the ollowing igure:
Fiber mode: multimode
Wavelength: 850µm
The transceiver can operate with a variety o iber optic
sizes, or example, 50/125µm, 62.5/125µm, and 100/140µm.
Setting Switches
There are two switches which are accessible on the side o
the transceiver enclosure. The unctions o these switches
are:
SW# Setting Function
SW1 On Enable SQE test (factory default)
Off Disable SQE test (for repeater device)
SW2 On Full-duplexmode
Off Half-duplex mode (factory default)
Important:
The transceiver is shipped rom the actory with the SQE
test enabled. I the transceiver is connected to an Ethernet
repeater, a 10Base-T hub, or a wiring concentrator, the SQE
test unction should be disabled.

Interpreting LED Indicators
There are our diagnostic LED indicators provided on the
transceiver to indicate the operation status as below:
LED Operation statusState Interpretation
Link Cable link status On The cable link is ok
Off No cable link or the link is
faulty.
Blink The cable link is faulty.
TRX Transmission status Blink Transmission is in operation.
Off No transmission.
On Normal, if large transmission is
in operation.
Problem, if no transmission.
RCV Receiving status Blink Receiving data packet
Off No packet is being received.
On Normal, if heavy traffic load.
Problem, if no network traffic.
COL Collision status Off No collision occurs.
Blink There is presence of collisions.
Installation
Attaching to an Ethernet device via an AUI cable
The Ethernet device can be a network inter ace controller,
wiring concentrator, or repeater that provides an AUI port.
For attaching to such device, an AUI cable o appropriate
length is required. The ollowing igure illustrates the
connection o the transceiver and an Ethernet device via
an AUI cable.
Important:
I the transceiver is attached to an Ethernet repeater, a
10Base-T hub, or a wiring concentrator, the SQE test
unction should be disabled.
Connecting to a fiber optic cable segment
The transceiver has two ST emale connectors or hooking
up to a duplex iber optic cable segment. One ST connec-
tor is used or transmitting data and the other one is used
or receiving data. Two iber optic cables are required to
compose a duplex cable segment between the transceiver
and the Fiber Optic port at the other end o the cables.
The Fiber Optic port at the other end o the cables must
comply with IEEE 802.3 10Base-FL standard.
