Revision
User's manual for PLANET Fast Ethernet Converter
Model: FT-712, FT-722, FT-733, FT-744
Rev 1.0 (Feb. 2000)
Part No. EMFT722V1
1. Overview
Thank you for purchasing PLANET FT-7XX family Fast Ethernet
Fiber-optic 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 19” media
chassis (up to 10 units) for a multi-mode and single-mode 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-712 : one onboard ST and SC fiber connector
ð FT-722 : two on board SC fiber connectors
ð FT-733 : two on board MT-RJ fiber connectors
ð FT-744 : two on board VF-45 fiber connectors
In the following sections, the term “FT-7XX” indicates the product
family above, the term “MM” and “SM” represent Multi-Mode and
Single Mode fiber-optic mode.
3. Checklist
Your FT-7XX carton should contain the following items:
ð The Fast Ethernet Converter
ð AC-DC Power Adapter (Output: 5VDC, 1 A max.)
ð This user’s guide
If any item is missing or damaged, please consult the dealer from
whom you purchased your Fast Ethernet Converter.

Multi Mode
Single Mode
Right View (FT-712/FT-722)
Two fiber-optic connectors, multi-mode on the left, single-mode
on the right and five LED indicators.
For FT-733, FT-744, the outlook of fiber port is accordant to its
related port, i.e. MT-RJ or VF-45.
Rear View (FT-7XX)
One DC jack for DC power input.
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-7XX will be attached
• Ensure that there is no activity in the network
2
• Attach MM fiber cables from the FT-7XX to the MM fiber
network. TX, RX must be paired at both ends
• Attach SM fiber cables from the FT-7XX to the SM fiber
network. TX, RX must be paired at both ends.
• Connect the 5VDC power adapter to the FT-7XX and verify
that the Power LED lights up.
• Turn on the power of the device/station, the Link and LEDs
should light when all cables are attached

Note:
n To prevent from optic acceptor malfunction, check the both
wires before power on the converter.
6. Duplex Mode setting
The FT-7XX is a transparent device between the two fiber
networks, please make sure the both networks are set to the same
duplex environment, or you may get a worse performance in both
networks. Connect with full-duplex Fast Ethernet networks are
strongly recommended.
7.LED indication

FX ACT Green Blinks when any FX packet is present
FX Link Green Lit when Fiber connection is good
PWR Green Lit when +5VDC power detected
8. Cable Connection Parameter
Fast Ethernet 100Base-X networks allows 512bit time delay
between any two node stations in a collision domain.
The overall bit time of Fiber wires and devices must be within 512
bit time in a 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.)
