1. Overview
Thank you for purchasing PLANET GT-9XX family Gigabit 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 Gigabit Ethernet Converter comes with one of the following models.
ð GT-922 : two on board SC fiber connectors
ð GT-933 : two on board MT-RJ fiber connectors
In the following sections, the term “GT-9XX” indicates the
product family above, the term “MM” and “SM” represent MultiMode and Single Mode fiber-optic mode.
3. Checklist
Your GT-9XX carton should contain the following items:
ð The Gigabit 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 Gigabit 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 GT-9XX will be attached
• Ensure that there is no activity in the network
• Attach MM fiber cables from the GT-9XX to the MM fiber
network. TX, RX must be paired at both ends
• Attach SM/MM* fiber cables from the GT-9XX to the SM
fiber network. TX, RX must be paired at both ends.
• Connect the 5VDC power adapter to the GT-9XX and verify
that the Power LED lights up.
• Turn on the power of the device/station, the SD LEDs should
light when all cables are attached

The GT-9XX 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
