1. Introduction
Transition Networks M/GE-xSW-SFP-01-xx-UxX Series are 10/100/1000Base-T to 100/1000Base-X Mini Gigabit
Ethernet Uni-Directional Media Converters.
Uni-directional communication is often used to safeguard information in secure environments such as
government agencies and military networks. A uni-directional device, sometimes referred to as a uni-directional
security gateway or a data diode, provides a connection between two or more networks with different security
classifications and helps to protect assets by ensuring information is directed only to, or from, the appropriate
network as designated by the directional device.
Uni-directional media converters combine this one-way communications with the benefits of a copper to fiber
media converter. Media converters are generally cost-effective, plug-and-play devices that allow fiber optic
cabling to be connected to copper-based networking equipment. The deployment of fiber adds a layer of security
to networks as it is difficult to tap into fiber and go undetected. If threats are attacking a network, the fiber links
usually go down and network administrators are made aware of the problem, providing them the opportunity to
address a potential breach of security.
Adding uni-directional technology to a media converter creates a physically secure one-way communication
channel between a secure network and an unsecure network. These devices can be used to allow data from a
classified, high-security area to be transmitted to a low-security area, while preventing unsecure data from
reentering the classified network. An alternative application allows a secure network to be updated with data
from an external source while ensuring its critical data is unable to leave the classified area.
Feature Benefits
•Uni-directional data transmissions to, or from, secure networks.
•Simplex communications only requires one strand of fiber cable.
•Applications require a transmit-only converter to be paired with a receive-only converter.
•Converters support dual speed 100/1000Mbps SFP modules offering great flexibility to meet network
requirements.
•Converters use duplex SFP modules but the transmitting converter only uses the TX port on the SFP, while
the RX port is deactivated. Likewise the receiving converter only uses the RX port, while the TX port is
deactivated.
•Secure transmission of data where two-way communication is undesirable.
•Provides a highly reliable, tamper proof converter for uni-directional transmission.
•Allows the transmission of data from a secure area to an unsecure area, while preventing unsecure data
from getting back into the secure area.
•Secured mirroring and recording at off-site location.

33781 Rev. B https://www.transition.com/ Page 8 of 22
Connect Fiber Cables
Full duplex (always ON) is on the fiber side only, therefore, the 512-Bit Rule does not apply. Cable lengths are
constrained by the cable requirement.
1. Use a 1000Base-SX or -LX10 fiber cable with male, two-stranded TX to RX connectors at each end.
2. Connect the fiber cable to the M/GE-xSW-SFP-01-xx-UxX Series 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 ( 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.
Connecting Single-strand Fiber Cable
Single-strand fiber cable can only be used if the SFP module installed in the converter also supports bi-directional
single strand fiber.
The uni-directional functions of these converters are controlled within the converter; therefore a duplex fiber
cable can be used. Or, a simplex fiber cable can be used between the transmitting converter and the receiving
converter. Additionally, bi-directional single-strand fiber can be used with these converters.
If using a simplex single-strand fiber cable, it is OK to leave open the unused Receive port or unused Transmit port
on the converters; the converter will not try to transmit or receive data on these unused ports.

Transition Networks M-GE-xSW-SFP-01-xx-UxX Series User Guide
33781 Rev. B https://www.transition.com/ Page 9 of 22
Connect 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 half-duplex mode is used, refer to the 512-Bit Rule.
•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 a 10Base-T or 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/GE-xSW-SFP-01-xx-UxX Series
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 ,

33781 Rev. B https://www.transition.com/ Page 11 of 22
Removing an SFP Module
Caution: Be careful when removing the SFP from a device. Some SFP transceiver module temperatures may
exceed 160°F (70°C) and be too hot to touch with bare hands. Note: Do not remove and replace the SFP modules
more often than necessary; excessive SFP removing and replacing can shorten the SFPs useful life.
1. Attach an ESD-preventive wrist strap to your wrist and to the ESD ground connector or a bare metal surface on
your chassis.
2. For future reattachment of fiber-optic cables, note which connector plug is send (TX) and which is receive (RX).
3. Remove the SFP transceiver module:
a. If the SFP transceiver module has an actuator button latch, gently press the actuator button on the front of
the SFP transceiver module until it clicks and the latch mechanism releases the SFP transceiver module from
the socket connector. Grasp the actuator button between your thumb and index finger, and carefully pull the
SFP transceiver module straight out of the module slot.
b. If the SFP transceiver module has a bail clasp latch, pull the latch out and down to eject the SFP transceiver
module from the socket connector. If the bail clasp latch is obstructed and you cannot use your index finger to
open it, use a small, flat-blade screwdriver or other long, narrow instrument to open the bail clasp latch. Grasp
the SFP transceiver module between your thumb and index finger, and carefully remove it from the socket.
4. Replace the Dust Plug.
5. Place the removed SFP transceiver module in an antistatic bag or other protective package.

Feature Descriptions
The M/GE-xSW-SFP-01-xx-UxX Series features include Congestion reduction, Auto-Negotiation, AutoCross,
Automatic link restoration, Full-Duplex flow control, Half-Duplex flow control, Distance extension, and Rate
conversion. These features are described below.
Congestion Reduction
The M/GE-xSW-SFP-01-xx-UxX Series media converters do not forward collision signals or error packets from one
collision domain to another, resulting in improvements in baseline network performance. In addition, the media
converter filters packets destined for local devices, which reduces network congestion.
Auto-Negotiation
The Auto-Negotiation feature is ON permanently for the M/GE-xSW-SFP-01-xx-UxX Series 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 (10 Mb/s or 100 Mb/s) and duplex capabilities (full or half) 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 that second device then establishes the best operating speed (10Mb/s
or 100Mb/s) at half duplex.
AutoCross
The AutoCross feature allows using either straight-through (MDI) or crossover (MDI-X) copper cables when
connecting to 10Base-T or 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.
Full-Duplex Flow Control
In a full-duplex network, maximum cable lengths are determined by the type of cables used—see page 1 (front
cover) for M/GE-xSW-SFP-01-xx-UxX Series cable specifications. The 512-Bit Rule does not apply in a full-duplex
network. Note: Full duplex is ON permanently for the fiber port only.
Half-Duplex Flow Control (512-Bit Rule)
In a half-duplex network, the maximum cable lengths are determined by the roundtrip delay limitations of each
Fast Ethernet collision domain. A collision domain is the longest path between any two terminal devices (e.g., a
terminal, switch, or router.) The 512-Bit Rule determines the maximum length of cable permitted by calculating

Transition Networks M-GE-xSW-SFP-01-xx-UxX Series User Guide
33781 Rev. B https://www.transition.com/ Page 16 of 22
the round-trip delay in bit-times (BT) of a particular collision domain. If the result is less than or equal to 512 BT,
the path is good.
Rate Conversion
The M/GE-xSW-SFP-01-xx-UxX Series media converters allow connection of 10Mb/s terminal devices on a 10Base-
T legacy Ethernet copper network to 100Mb/s terminal devices on a 100Base-TX Fast Ethernet copper network
and/or to 100Mb/s terminal devices on a 100Base-FX or -LX10 Fast Ethernet fiber network.
Distance Extension
The M/GE-xSW-SFP-01-xx-UxX Series media converters can segment one (1) 10Base-T copper Ethernet and/or
100Base-TX copper Fast Ethernet, and one (1)100Base-FX or –LX10 fiber Fast Ethernet collision domain:
•In a half-duplex Ethernet or Fast Ethernet environment, the M/GE-xSW-SFP-01-xx-UxX Series media
converters extend network distances by segmenting collision domains so that the 512-Bit Rule applies
separately to each collision domain.
•In a full-duplex Ethernet or Fast Ethernet environment, the M/GE-xSW-SFP-01-xx-UxX Series media
converters extend network distances to the physical cable limitations imposed by the selected twisted-
pair copper fiber cables.
