2.8.2 Power Extractor

The Power Extractor, installed close to the MPT-HC, allows to interconnect the MSS and the MPT-HC with
a single electrical Ethernet cable by using the "Power Feed over Ethernet" solution (Ethernet traffic and
Power Supply on the same cable). The Power Extractor then separates the Power Supply from the Ether-
net traffic, which are separately sent to the MPT-HC.
The two cables, interconnecting the Power Extractor to the MPT-HC (the Power Supply cable to be con-
nected to the DC Out connector of the Power Extractor and Ethernet cable to be connected to the Data
Out connector of the Power Extractor), are provided, already terminated (2 m long), with the Power
Extractor itself.

2.8.3 Power Injector

The Power Injector is an indoor device designed to deliver the DC power supply to MPT (as shown in para-
graph 2.1.10 on page 58) by using the same cable carrying the Ethernet traffic.
The Power Injector receives at the input the Ethernet traffic and the power supply on two dedicated con-
nectors and sends to the output on one connector the Power Supply + Ethernet Traffic. This solution,
called PFoE (Power Feed over Ethernet), is proprietary.
The Power Injector can supply up to 2 MPT.
The two Power Supply Sources provide power supply redundancy.
Main functions of the injector
– Securization of two DC power inputs from -48V battery
– Low pass filtering
– Insertion of the DC voltage on two Ethernet streams to power two MPT units
– Surge protection on both Ethernet output ports (K44 & K45)
