Eclipse Odus - Harris Stratex Eclipse 4.6 User Manual

Chapter 1. System Overview

Eclipse ODUs

There are three mechanically similar ODUs. They are band specific and supplied with
diplexers for Tx high or Tx low working. The one exception is at 5 GHz, where ODU
300ep is software-switched for Tx high or Tx low, and a 7/16" female DIN connector
replaces the waveguide port used on all higher bands.
• ODUs for 6 to 38 GHz are designed for direct-antenna mounting, but can be remote
mounted.
• The 5 GHz ODU 300ep requires remote mounting, and is supplied with a
remote-mount installation kit.
All ODUs support ATPC.
ODUs are frequency-band specific, but within each band are capacity independent up
to their design maximums. Main performance characteristics of the ODU 300 series
summarized in
ODU 300
There are three ODUs for Eclipse INUs and IDUs:
• ODU 300sp
• ODU 300hp
• ODU 300ep
Channel bandwidths range from 3.5 to 56 MHz depending on the ODU, band-plan, and
capacity/modulation option selected.
ODU 300ep availability is now limited to 5, 13 and 15 GHz. It is required for 5 GHz, and
is an option at 13 and 15 GHz.
Within their band limitations the ODU 300hp and ODU 300ep are over-air
compatible. Both are supported from RAC 30, RAC 40, RAC 3X, RAC 4X, or 300 series
IDUs, except IDUsp for the ODU 300ep.
The lower capacity ODU 300sp is only over-air compatible with another ODU 300sp,
and is supported from RAC 30, and all 300 series IDUs except IDU 155o.
ODU 300sp supports:
• 7 to 38 GHz
• Standard power transceiver
• 2x to 40x E1
• Up to 80 Mbps Ethernet
• QPSK or 16 QAM modulation
• RAC 30, IDU 300 series except IDU 155o
ODU 300hp supports:
• 6 to 38 GHz
• High power transceiver

A QPSK-only variant is available for 8, 13, and 15 GHz bands.
