Introduction
Transition Networks' Ethernet Over 2-Wire Extenders with PoE+ (EO2P) are used in pairs, with a
local or remote device at opposite ends of the UTP cable. The extenders are the most flexible in
the market, with a 10/100/1000Base-T RJ-45 connector or 100/1000Base-X SFP combo port
allowing connection to either copper or fiber Ethernet devices. The Local device provides a
Gigabit 2-wire terminal block or RJ-45 connection to provide SELV power over twisted pair cable
to the Remote device. The Remote device receives data and power through the 2-wire terminal
block or RJ-45 connection and provides either a 100/1000Base-X SFP or 10/100/1000Base-T RJ-45
connector output with PoE+ power for IP cameras, wireless access points or other PoE powered
end devices. Power for the Local device can be supplied through a +48VDC power source that
meets IEEE 802.3af/at isolation requirements of 1500VAC or 2200VDC or through the designated
90 Watt power adapter. The designated 90 Watt power adapter is optional at the Remote device
for additional power or for providing redundant power.
Transition Networks EO2P are a flexible and cost-effective way to extend Ethernet networks at
near Gigabit speeds and provide full PoE+ power to security cameras, wireless access points or
other IP end devices at distances beyond the typical 100m Ethernet cable limitation.
The EO2P leverage the existing 18-24 AWG unshielded twisted pair (CAT6/5, CAT3, or 2-wires of
other 18-24 AWG UTP cable) cabling infrastructure to provide data and safety extra low voltage
(SELV) power to IP/Ethernet devices in remote locations, saving time and money over installing
new cable and electric power when upgrading or extending networks.

Port Descriptions
The extenders leverage existing 18-24 AWG unshielded twisted pair (CAT 5, CAT 3 and
other 2-wire phone wire) cabling infrastructure to extend the Ethernet network at near
Gigabit speeds and provide data and power to IP devices in remote locations.
These extenders are used as a pair of devices, with a local and remote unit at opposite ends of
the 2 Wire cable. The local unit can accept a 10/100/1000Base-T RJ-45 or 100/1000Base-X SFP
connection. The local device also provides a 2 Wire connection with power over two-wire.
The remote device can be powered by the 2 Wire Power connection and provides a PoE+
10/100/1000Base-T RJ-45 connection, or a 100/1000Base-X SFP connection.
Connections
This section illustrates and describes connecting the EO2PSE4052-111 (Local PSE unit with
GB combo RJ45/SFP and 2 Wire) to the EO2PD4052-111 (Remote PD unit with 2 Wire and
GB combo RJ45 PoE+/SFP).
EO2PSE4052-111 EO2PD4052-111
Local PSE Unit Remote PD Unit
Network Connection
The EO2PSE4052-111 offers a Combo (Shared) port for connecting to either copper or
fiber network equipment.
In terms of copper versus fiber port selection / priority, only one port can be active at
any given time; by default the SFP port takes precedence over the copper port
(configurable on the Ethernet Web GUI page).
SFP / Fiber Connection
The SFP port supports any MSA compliant 100/1000Base-X SFP module. For
temperatures above +50 C, industrial (+85 C) SFP modules must be used.

EO2P User Guide |Page 12
33706 Rev. A
Installing SFP Devices
The EO2P lets you install a SFP device of your choice in order to make a fiber
connection. The EO2P has a single SFP port.
SFP Installation
Transition Networks SFPs are small form factor, hot-pluggable transceivers which allow
for a single piece of network equipment to be connected to a multitude of interfaces,
protocols, and transmission media via the SFP port. All Transition Networks SFPs are
compliant with the Multi-Sourcing Agreement (MSA) ensuring interoperability with all
other MSA compliant networking devices. See SFF-8472 Specification for details.
See the SFP manual for important Safety cautions and warnings.
To install an SFP device in the EO2P:
1. Position the SFP device at the open SFP slot, with the label facing up.
2. Carefully slide the SFP device into the slot, aligning it with the internal installation
guides.
3. Ensure that the SFP device is firmly seated against the internal mating connector.
4. Connect the fiber cable to the fiber port connector of the SFP device (see above).
See the TN SFP/XFP Optical Transceivers web page for the latest information.

EO2P User Guide |Page 13
33706 Rev. A
Connecting Two-strand Fiber Cable
A duplex fiber cable consists of two strands of glass or plastic fiber. Typically found in a “zipcord”
construction format, this cable is most often used for duplex communication between devices
where a separate transmit and receive are required.
1. Locate a 100/1000Base-X compliant fiber cable with male, two-stranded TX to RX connectors
installed at both ends.
2. Connect the fiber cables to the EO2P’s 100/1000Base-X fiber port as described below:
• Connect the male TX cable connector to the female TX connector.
• Connect the male RX cable connector to the female RX connector.
3. Connect the fiber cables to the 100/1000Base-X fiber port on the other EO2P:
• Connect the male TX cable connector to the female RX connector.
• Connect the male RX cable connector to the female TX connector.
For information on available SFP modules, see the Transition Networks Small Form factor
Pluggables webpage. For information on specific SFP characteristics, unpacking, installation,
connecting, and removing see the specific SFP User Guide.
Connecting Single-strand Fiber Cable
Single fiber (simplex) technology helps maximize the usage of a limited number of fiber runs.
In a traditional optical link, a fiber pair consists of two uni-directional strands. Single fiber
technology multiplexes two optical wavelengths of 1310nm and 1550nm into a single strand fiber.
In a single fiber EO2P each wavelength is responsible for either the transmit or the receive
function. Consequently, the bi-directional transmission is achieved by using a single strand.
The EO2Ps in a single fiber scenario "match" each other's wavelengths. For example, one EO2P
transmits at the wavelength of 1310nm and receives at 1550nm while the other EO2P transmits
at 1550nm and receives at 1310nm. The EO2Ps are used in pairs.
1. Locate or build IEEE 803.2™ compliant 1000Base-X fiber cable with a male, single-strand LC
connector installed at each end.
2. Connect the fiber cable to the EO2Ps.
3. Connect the fiber cable to the other device (another EO2P, hub, etc.).
