Introduction
Transition Networks’M/E-TX is a series of Fast Ethernet stand-alone Mini media converters that provide
cost effective media conversion between 100Base-TX ports and 100Base-FX ports. With its fixed
configuration, deployments are just plug-and-play, and its small size makes it ideal for locations where
space is limited. Operating at Layer 1, the physical layer, data is passed through the converter at line speed,
making it ideal for applications where low latency is essential.

Features
•Fiber integration used in pairs or as a single unit, this mini media converter will ease the integration
of fiber optic cabling into copper-rich fast Ethernet environments
•Extend Network Distance as fiber supports the transmission of Fast Ethernet data over much longer
distances than possible twisted pair
•Low-Latency Layer 1 Design, this mini converter will retransmit Fast Ethernet signals without any
store-and–forward packet inspection delays found in other Layer 2 devices
•Small Size is ideal for conversion locations where available space is limited - 65% smaller than
standard media converters
•Unit and port LEDs allow for quick status information
•Auto-Negotiation and Auto-MDI/MDIX

CAUTION: Copper based media ports, e.g., Twisted Pair (TP) Ethernet, USB, RS232, RS422, RS485, DS1,
DS3, Video Coax, etc., are intended to be connected to intrabuilding (inside plant) link segments that are
not subject to lightening transients or power faults. These Copper-based media ports are NOT to be
connected to interbuilding (outside plant) link segments that are subject to lightening transients or
power faults. Failure to observe this caution could result in damage to equipment.
WARNING: Visible and invisible laser radiation when open. Do not stare into the beam or view directly
with optical instruments. Failure to observe this warning could result in an eye injury or blindness.
WARNING: Use of controls, adjustments, or the performance of procedures other than those specified
herein could result in hazardous radiation exposure. The information in this user guide is subject to

Installation
10BObserve ESD Precautions
Always observe the following ESD (Electrostatic Discharge) precautions when installing or handing the
media converter:
•Do not remove the converter from its protective packaging until you are ready to install it.
•Wear an ESD wrist grounding strap before handling any module or component. If you do not have a
wrist strap, maintain grounded contact with the system unit throughout any procedure requiring
ESD protection.
11BCopper and Fiber Ports
The figure below shows the front panel of the M/E-TX-FX-01 media converters.

Transition Networks, Inc. M/E-TX-FX-01 User Guide
33517 Rev. B https://www.transition.com/ Page 6 of 12
Connect the Fiber Cable
Full duplex (always ON) is on the fiber side only; therefore, the 512-Bit Rule does not apply. The cable
lengths are constrained by the cable requirement.
1. Locate or build IEEE 803.2 compliant 100 Base-X fiber cable with male, two-stranded TX to RX
connectors installed at both ends.
2. Connect the fiber cable to the M/E-TX-FX-01 media converters as follows:
•Connect the male TX cable connector to the female TX port.
•Connect the male RX cable connector to the female RX port.
3. Connect the fiber cable to the other device (another media converter, hub, etc.) as follows:
•Connect the male TX cable connector to the female RX port.
•Connect the male RX cable connector to the female TX port.
13BConnect the Twisted-pair Copper Cable
The AutoCross feature allows either MDI (straight-through) or MDI-X (crossover) cable connections to be
configured automatically, according to network conditions.
•If full-duplex mode is used, the 512-Bit Rule does not apply. The cable lengths are constrained by the
cable requirements.
Perform these steps:
1. Locate or build IEEE 803.2™compliant 100Base-TX cable, with RJ-45 connectors installed at both
ends.
2. Connect the RJ-45 connector at one end of the cable to the RJ-45 port on the M/E-TX-FX-01 media
converter.
3. Connect the RJ-45 connector at the other end of the cable to the RJ-45 port on the other device
(switch, workstation, etc.).

14BPower Warnings
WARNING: If the media converter is an IEEE802.3-2005 Powered Device (PD) capable of receiving power
via the Media Dependent Interface (MDI) leads, the power source, connector, and cables attached to
the barrel power connector must meet the isolation requirement specified in IEEE 802.3-2005.
Power Supply Included
To order the corresponding country- specific power supply, add the extension from the list below to
the end of the SKU. For example: M/E-TX-FX01-NA = North America, -LA = Latin America, -EU = Europe,
-UK = United Kingdom, -SA = South Africa, -JP = Japan, -OZ = Australia, and -BR = Brazil.

22BAC Power
1. Connect the barrel connector of the power adapter to the media converter’s power port (located on
the back panel of the media converter).
2. Connect the power adapter plug to AC power.
3. Verify that the media converter is powered up by observing the lit power indicator LED on the front
panel.

18BFeatures
24BAuto-Negotiation
The Auto-Negotiation feature is ON permanently for the M/E-TX-FX-01 media converters. Auto-
Negotiation allows the media converter to configure itself automatically to achieve the best possible
mode of operation over a link. It broadcasts speed (100 Mbps) and duplex capabilities (full) to the other
device and negotiates the best mode of operation. Auto-Negotiation allows quick and easy installation
because the optimal link is established automatically.
In a scenario where an auto-negotiation device is linked to a non-negotiating device, the negotiating
device via parallel detection recognizes the speed of the second device then establishes the best
operating speed (100 Mbps).
25BAutoCross
The AutoCross feature allows using either straight-through (MDI) or crossover (MDI-X) copper cables
when connecting to 100Base-TX devices. AutoCross determines the characteristics of the connection
and automatically configures the device to link up, regardless of the copper cable configuration (MDI or
MDI-X).
26BAutomatic Link Restoration
The media converter will automatically re-establish the link when connected to a switch if the link is lost,
even with Auto-Negotiation enabled.
27BFar-End Fault (Always ON)
When a fault occurs on an incoming fiber link (1), the media converter transmits a Far-End Fault signal
on the outgoing fiber link (2).

6BTroubleshooting
If the media converter fails, isolate and correct the failure by determining the answers to the following
questions, and then taking the indicated action:
1. Is the power LED lit and did the TX and FX LEDs turn ON and then turn OFF?
NO
•Is the device powered by an adapter?
•Is the power adapter the proper type of voltage and cycle frequency for the AC outlet?
•Is the power adapter properly installed in the media converter and in the AC outlet?
•Contact Technical Support: See Contact Us below.
YES
Proceed to step 2.
Note: the M/E-TX-FX-01 (no link pass-through option), the TX LED will turn ON when the twisted pair
copper cable is installed; the FX LED will turn ON when the fiber cable is installed.
2. Are the TX and FX-Link/ACT LEDs lit on the RJ-45 port?
NO
Check the copper cables for proper connection.
Check the fiber cables for proper connection.
