Overview
Thank you for purchasing PLANET FT-80X family 10/100Mbps
Ethernet Twisted pair to 100Base-FX Fiber-optic Bridge Converter.
This converter is used to convert one type media signal to other
type equivalent that allows two type segments connect easily,
efciently and inexpensively. This converter can be used as a
standalone unit or as a slide-in module to the 10”/19” media
chassis (up to 15 units) for a TP and Fiber combined networks at a
central wiring closet. Please contact with your sales representative
for more about the 19” media chassis.
Chapter 2
Model List
Your Fast Ethernet Converter comes with one of the following
models.
ð FT-801: on board ST fiber connector
ð FT-802/S: on board SC fiber connector
ð FT-803: on board MTRJ fiber connector
ð FT-806A20: on board single SC fiber connector
ð FT-806B20: on board single SC fiber connector
Models with last character “S” indicate the ber-port is with
“Single-Mode” optic ber connector and followed with a number
indicates the maximum wiring distance.
In the following sections, the term “FT-80X” indicates the product
family above.

Product Outlook
Right View
There are one RJ-45 Twisted-Pair jack (Auto-MDI/MDI-X), one
ber-optic connector (vary by model) and six LED indicators.
Left View
One DIP switch for Fiber-optic operating mode selection, FDX for
full-duplex, and HDX for half-duplex.

Side View (FT-80X)
One DIP switch for Link Fault Pass Through (LFP) feature, “ON”
to turn-on the LLCF and LLR detection. And “OFF” to turn–off this
feature. Please refer to the following sections for more.
DIP Switch for LFP function.
Chapter 5
Link Fault Pass through (LFP)
The LFP function includes the Link Fault Pass Through function
(LLCF/LLR) and the DIP Switch design. LLCF/LLR can immediately
alarm administrators the problem of the link media and provide
efcient solution to monitor the net. The DIP Switch provides
disable or enable the LFP function.
LLCF (Link Loss Carry Forward) means when a device connected
to the converter and the TP line loss the link, the converter’s ber
will disconnect the link of transmit. LLR (Link Loss Return) means
when a device connected to the converter and the ber line loss
the link, the converter’s ber will disconnect the link of transmit.
Both can immediately alarm administrators the problem of the link
media and provide efcient solution to monitor the net.

Link Loss Carry Forward (LLCF)
FT-80X incorporates an LLCF function for troubleshooting a
remote connection. When LFP function is enabled, the FL/TP ports
do not transmit a link signal until they receive a link signal from
the opposite port.
The diagram below shows a typical network conguration with a
good link status using FT-80X for remote connectivity.
If the connection breaks, FT-80X that link loss forward to the
switch/hub that generates a trap to the management station. The
administrator can then determine the source of the problem.
*Units are shipped with the LFP function enabled (ON).
Link Loss Return (LLR)
The ber ports of FT-80X have been designed with an LLR function
for troubleshooting a remote connection. LLR works in conjunction
with LLCF.
When LFP function is enabled *(by default), the port’s transmitter
shuts down when its receiver fails to detect a valid receive link.
LLR should only be enabled on one end of the link and is typically
enabled on either the unmanaged or remote device.
The diagram below shows a typical network conguration with a
good link status using FT-80X for remote connectivity. Note that
LLR and LLCF are enabled as indicated in the diagram.

5
If one of the optical conductors is bad (as shown in the diagram
box below), the converter with LLR function will return a no-link
condition to its link partner. With LLCF function also enabled, the
no-link condition is carried forward to the switch/hub where a trap
is generated to the management station, and the administrator
can then determine the source of the loss.
NOTE:
LFP function is turn-on in default. This feature
can also be turned off via the side DIP-switch.
If you are familiar with the network installation
and for diagnostic purpose (i.e. check which
end is broken), you can turn it off and reset
the converter to make it take effect. Otherwise,
please remains it in the default position.

Installing the Converter
Please follow these steps to install the converter:
• Turn off the power of the device/station in a network to
which the FT-80X will be attached
• Ensure that there is no activity in the network
• Attach fiber cable from the FT-80X to the fiber network.
TX, RX must be paired at both ends
• Attach a Cat. 5 UTP cable from the 10/100Base-TX net-
work to the RJ-45 port on the FT-80X.
• Connect the 5VDC power adapter to the FT-80X and
verify that the Power LED lights up.
• Turn on the power of the device/station, the TX Link and
FX Link LEDs should light when all cables are attached
• Turn on the power of the device/station, the TX Link and
FX Link LEDs should light when all cables are attached
NOTE:
• RJ-45/STP, UTP Cat 5, straight/crossover
cable is accepted
• Please refer to section 8 for more about
the wiring distance of your TP, Optic-ber
networks.
