Chapter 3. System Overview
This section overviews features and capabilities of Eclipse with IRU 600 for the 5.8
GHz unlicensed band.
Eclipse with IRU600, 5.8 GHz, is compliant with FCC CFR47, Part 15.247.
• It has been tested and certified for use with a parabolic antenna with a maximum
gain of 46.8 dBi.
• The filters used in the IRU 600 RF unit allow for transmission only in the frequency
range 5725 - 5850MHz to ensure compliance with Part 15.247.
• Transmit power output is limited to 1W (30 dBm) at the antenna port to comply with
the conducted power limit in FCC CFR 47, Part 15.247.
Operation is all-indoor, using rack-mounted indoor units, the INU and INUe, and one
or more IRU 600 RF units.
• Eclipse supports multiple radio links from a common indoor unit with throughput
capacities to 189 Mbit/s Ethernet, 100xDS1, 3xDS3, or 1xOC3.
• The IRU 600 RF unit is 1+1 optimized with two RFUs and an ACU. The RFUs can be
operated as independent links, or as a protected link.
• Path, equipment, and data protection options support comprehensive link, network
and data redundancy.
•Plug-in cards on the INU and INUe provide a wide choice of user interfaces and radio
link operation.
• The node-based concept eliminates most ancillary equipment and external cabling,
and offers smooth upgrade paths for next generation networks.

MEF Certified. Eclipse meets the requirements of MEF 9 and MEF 14
for carrier-class Ethernet inter-operability and performance. MEF 9
specifies the User Network Interface (UNI). MEF 14 specifies Quality of
Service (QoS).
