Introduction

The SI-IES-111D-LRT and SI-IES-121D-LRT are designed to convert Gigabit fiber networks
to Gigabit Ethernet networks by transparently converting optical signals to Ethernet signals
with IEEE 802.3af (PoE) or IEEE802.3at (PoE+) PSE function.
The devices can provide full 30W (PoE+) or 15 W (PoE) to each copper port to provide power
and data over an RJ-45 cable. The advantages of the fiber optic connection are wide
bandwidth, EMI immunity and long-distance transmission capability. This makes the
Hardened PoE Injector/Converter an ideal solution for "fiber to the building" applications at
central offices or local sites. The Hardened PoE/PoE+ Injector/Converter supports MDI/MDIX
auto detection, and can operate in a temperature range from -40
case makes the device suitable for harsh operating environments.
SI-IES-111D-LRT
SI-IES-111D-LRT has one SFP slot and one RJ45 port. The RJ45 port supports IEEE 802.3af
(PoE) and 802.3at (PoE+), and can provide up to 30W for high powered application. The SFP
slot provides more flexibility when planning and implementing the network. The slot can accept
a dual speed 100/1000M SFP fiber module. This makes it possible to easily change the
transmission mode and distance of the connection by using a different module. The SFP
module is hot-swappable, and there is a DIP switch to adjust the SFP function.
SI-IES-121D-LRT
SI-IES-121D-LRT has one SFP slot and two RJ45 ports. The RJ45 ports support IEEE 802.3af
(PoE) and 802.3at (PoE+), and can provide up to 30W on each copper port for high power
applications. The SFP slot provides more flexibility when planning and implementing the
network. The slot can accept a dual speed 100/1000M SFP fiber module. This makes it
possible to easily change the transmission mode and distance of the connection by using a
different module. The SFP module is hot-swappable, and there is a DIP switch to adjust the
SFP function.
