User's manual for PLANET Fast Ethernet Converter
Multi-mode: FT-701B, FT-702B, FT-703, FT-704
Single-mode: FT-702S, FT-703S, FT-704S
Rev 1.0 (Feb. 2000)
Part No. EMFT70XV1
1. Overview
Thank you for purchasing PLANET FT-70X family Fast Ethernet
Twisted pair to 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 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-701B : on board ST fiber connector
ð FT-702B/S : on board SC fiber connector
ð FT-703/S : on board MT-RJ fiber connector
ð FT-704/S : on board VF-45 fiber connector
Models with last character “S” indicate the fiber-port is with
“Single-Mode” optic fiber connector.
In the following sections, the term “FT-70X” indicates the product
family above.
3. Checklist
Your FT-70X 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.

One RJ-45 Twisted-Pair jack, one fiber-optic connector and six
LED indicators.
For FT-703/S, FT-704/S, the outlook of fiber port is accordant to its
related port, i.e. MT-RJ or VF-45.

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-70X will be attached
• Ensure that there is no activity in the network
• Attach fiber cable from the FT-70X to the fiber network. TX,
RX must be paired at both ends
• Attach a Cat. 5 UTP cable from the 100Base-TX network to
the RJ-45 port on the FT-70X.
• Connect the 5VDC power adapter to the FT-70X 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
FT-70X
Note:
n RJ-45/STP, UTP Cat 5, straight-through cable is accepted
n Cabling from FT-70X TP port to a TP device is as below:
q To Workstation: DIP switch on DTE
q To Hub/Switch: DIP switch on MTR
n Please refer to section 8 for more about the wiring distance of
your TP, Optic-fiber networks.

6. Duplex Mode setting
The FT-70X support duplex mode selection by Auto-Negotiation
(A-N). The following is the duplex mode parameters:
Fast Ethernet Device FT-70X Duplex
Mode support
Fast Ethernet Hub Half-Duplex
Fast Ethernet Switch (without A-N) Half-Duplex
Fast Ethernet Devices *
Support Auto-Negotiation
Full-Duplex /
Half-Duplex
Note: Normally, an A-N switch will detect and set to Fullduplex where a dual-speed hub will detects Half.
7.LED indication
LED COLOR DESCRIPTION
FX ACT Green Blinks when any FX packets transmitting
FX Link Green Lit when Fiber connection is good
Blinks when any FX packets receiving
TP ACT Green Blinks when any TP packets transmitting
TP Link Green Lit when TP connection is good
Blinks when any TP packets receiving
FDX* Green Lit when Full-duplex mode is detected in
TP port
PWR Green Lit when +5VDC power detected
Note: Fiber-optic Partner should be set to the correct mode
according to this FDX indicator for optimal network performance.

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 TP/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.)

Half / Full Node to Node
Node to Switch/Hub
Multi-Mode Converters
MM Half Node to Node
Node to Switch
MM Full Node to Node
Node to Switch
