Eclipse Installation Manual
If one of the two FANs becomes faulty (FAN Fault alarm), always replace
both FANs. IRU 600 replacement FANs are supplied in a kit of two FANs.
Tx Monitoring Port
IRU 600v2 Tx filters incorporate a Tx monitoring port (SMA connector) to provide a
30 dB attenuated (nominal) sample for test and measurement purposes. A label on the
ACU shows the ex-factory insertion loss of the port.
5.8 GHz Unlicensed Band
The RFU for the 5.8 GHz unlicensed band is common to L6 licensed for easy transition
and sparing (from unlicensed to licensed and vice-versa). Links can be rapidly
deployed using 5.8 GHz unlicensed, and subsequently transitioned to L6 on license
approval.
The 5.8 GHz unlicensed band is designed to support easy and fast deployment. With a
suitable antenna, installation can be 'immediate'.
The common 5.8 GHz / L6 RFU design means subsequent conversion to
L6 licensed operation only requires replacement of the ACU.
5.8 GHz operation supports fast turn-up for new link requirements. On receipt of a
license, operation can be converted to L6 licensed band by replacing the ACU.
Eclipse IDUs and INUs with IRU 600 are compliant with FCC CFR47, Part 15.247, and
Industry Canada RSS-210 Annex 8, on ISM frequency band 5725 to 5850 MHz.
International use is not supported; the system does not employ DFS and as such
cannot be deployed within Europe
or any country where DFS is a regulatory requirement for protection of radars.
Features and Capabilities:
• ACU filters are tuned 30 MHz wide.
• Filters are spot tuned (pre-tuned) on 5740.5/5805.5 MHz or 5769.5/5834.5 MHz.
• With 30 MHz filters just two Tx/Rx pairs can be used to provide full coverage of
the band.
• Bandwidths 5, 10, 20, or 30 MHz.
• Tx and Rx can be paired on different sub-bands (Tx on one 30 MHz sub-band, RX on
the other).
• Adaptive or fixed modulation options.
• Supports Ethernet and/or NxDS1 payloads, with air-link capacities to 189 Mbit/s (30
MHz Ch BW).
