OVERVIEW
Thank you for purchasing PLANET GT-70X family Gigabit Ethernet
Media Converter products. This Gigabit Ethernet Media Converter
is used to convert one type media signal to other type equivalent
that allows two type segments connect easily, efciently and
inexpensively. The Giagbit Ethernet Media Converter introduced
here provides one channel media conversion between the
1000Base-T and 1000Base-SX/LX, 1000Base-SX/LX through SFP
Mini-GBIC(GT-705A only) or the 1000Base-LX WDM(GT-706A15/
B15 only).
This Gigabit Ethernet Media 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 multi-mode and single-mode Fiber combined
networks at a central wiring closet. Please contact with your sales
representative for more about the 10”/19” media chassis.
About the Gigabit Ethernet Media Converter
This Gigabit Ethernet Media Converter utilizes a netrwork
technology specied by IEEE 802.3ab 1000Base-T and IEEE802.3z
1000Base-SX/LX standards. The Gigabit Ethernet Media Converter
is used to converter one type media signal to other type equivalent
that allows two type segments connect easily, effciently and
inexpensively.

MODEL LIST
Your Gigabit Ethernet Converter comes with one of the following
models.
ð GT-702: 1000Base-T to 1000Base-SX (SC)
ð GT-702S:1000Base-T to 1000Base-LX (SC)
ð GT-705A: 1000Base-T to 1000BaseSX/LX (LC)
ð GT-706A15: 1000Base-T to 1000Base-LX(WDM)
ð GT-706B15: 1000Base-T to 1000Base-LX(WDM)
In the following sections, the term “GT-70X” indicates the product
family above, the term “MM” and “SM” represent Multi-Mode and
Single Mode ber-optic mode.
NOTE:
Please note GT-706A15/706B15 is designed
to work together. It means you must con-
nect GT-706A15 to GT-706B15 from them to
work normally. If both ends are GT-706A15
or GT-706B15, they can’t work normally and
may damage the fiber connectors.

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-70X will be attached.
• Ensure that there is no activity in the network.
• Attach fiber cable from the GT-70X to the fiber network.
TX, RX must be paired at both ends.
• Connect the 5VDC power adapter to the GT-70X and
verify that the Power LED lights up.
• Turn on the power of the device/station; the PWR LEDs
should light when all cables are attached.
Notice:
Please refers to section 9 for detailed wiring
information of the GT-70X.
To prevent from optic acceptor malfunction, check the both wires
/ transmitter before power on the converter.

DUPLEX MODE SUPPORT
The GT-70X is one-channel media conversion between 1000BaseT and 1000Base-SX/LX/LX WDM. 1000Base-T port can work
under Auto-negotiation and xed 1000Mbps full duplex mode.
1000Base-SX/LX/LX WDM ber port only allow to work under
xed 1000Mbps full duplex mode.
Notice:
It doesn’t support Auto-negotiation and can
not work with 1000Base-SX/LX interface
that can not configure to fixed 1000Mbps
full duplex.
