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).

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.
