1. Overview
Thank you for purchasing PLANET FT-722 Fast Ethernet
Fiber-optic Media Converter. This converter is used to convert
one type media signal to other type equivalent that allows two
type segments connect easily, efficiently 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.
2. Model List
Your Fast Ethernet Converter comes with one of the following
models.
ð FT-722Sxx: two on board SC fiber connectors
Sxx represents Single-model optic interface in xx kilometers.
In the following sections, the term “ FT-722” indicates the
product above, the term “MM” and “SM” represents
Multi-mode and Single Mode fiber-optic mode.
3. Checklist
Your FT-722 carton should contain the following items:
ð The Fast Ethernet Media Converter
ð AC-DC Power Adapter (Output: 5VDC, 2 A max.)
ð This user’s manual
If any item is missing or damaged, please consult the dealer
from whom you purchased your Fast Ethernet Converter.

5. 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-722 will be attached
• Ensure that there is no activity in the network
• Attach MM fiber cable from the FT-722 to the MM fiber
network. TX, RX must be paired at both ends
• Attach SM fiber cable from the FT-722 to the SM fiber
network. TX, RX must be paired at both ends.
• Connect the 5VDC power adapter to the FT-722 and
verify that the Power LED lights up.
• Turn on the power of the device/station, the LNK /ACT
LEDs should light when all cables are attached.

Note:
n To prevent from optic acceptor malfunction, check the
both end including, connectors, cable type (MM/SM), and
wiring distance before power on the Media Converter.
n DIP-switch LFP is turn on by default, any broken link will
cause the other end link down as well. To diagnose which
end is broken, please turn off the LFP and power off/on the
converter again. Please remains it on in normal operation.

DESCRIPTION
7. Cable Connection Parameter
Fast Ethernet 100Base-FX networks allow 512bit time delay
between any two-node stations in a collision domain.
The overall bit time of Fiber wires and devices must be within
512bit time in segment. To extend the distance, you may use
switch to break up a collision domain and extend the distance.
The limitations are as below:
Duplex Connection Limitation (max.)
Multi-Mode
MM Half Node to Node
Node to Switch
MM Full Node to Node
Node to Switch
Single-Mode
SM Half Node to Node
Node to Switch 412 meters*
SM Full Node to Node
Node to Switch
Note:
n In half-duplex mode, 412 meters is the maximum distance
between two devices. To force both devices to full-duplex
for optimal distance is strongly recommended.
412 meters*
2 kilometers
