Chapter 1. System Overview
Power Supply
Eclipse is designed to operate from a -48 Vdc power supply (+ve earth) but will operate
to specification over a voltage range of -40.5 to -60 Vdc.
The dc power supply must be UL or IEC compliant for a -48 Vdc SELV (Safety Extra
Low Voltage) output (60 Vdc maximum limited).
Platform Layout and Interoperation Data
300 Series IDUs
The table below describes the IDU 300 series platform support for non-protected and
protected operation, ODU options, and capacity and modulation.
Table 1-5, “Eclipse 300 Series IDU and ODU Parameters,” on page 20 summaries IDU/
ODU options and over-air compatibility.
To view detailed compatibility data for the IDU GE 20x, see IDU GE 20x Compatibility
on page 1-21.
Protected IDUs cannot be used to link to an INU/INUe. Where protected
IDUs are to be used they must be installed at both ends of the link.
