ECLIPSE INSTALLATION MANUAL
Eclipse IRU 600
The IRU 600 is a rack-mounted transceiver unit for co-location with an INU/INUe as
an all-indoor installation.
l IRU 600 is 1+1 optimized. It comprises one or two RFUs (radio frequency
units), and a filter-based ACU (antenna coupler unit).
o
The ACU design supports paired and unpaired Tx/Rx frequency splits and
incorporates an optional expansion port to allow other radio links onto its
waveguide feed for co-path operation.
o
Protected/diversity options include:
n 1+1 hot-standby, single antenna.
n 1+0 hot-standby-ready.
n Space diversity (dual antennas) with common or split Tx.
n Frequency diversity (single antenna) or frequency diversity with space
diversity (dual antennas).
o
1+0 repeater (back-to-back) single chassis operation is supported.
l IRU 600 is supported from a RAC 60E/6XE.
l NEBS compliant EMI filtering is standard (currently IRU 600(v1) and IRU
600v2). NEBS compliance for IRU 600v3 is planned.
l Labels on the ACU show filter and circulator losses and the total loss (filters,
circulators, switch and cables combined).
l When multiple IRU 600 links are combined onto a single waveguide feed for
ACCP operation, required minimum Tx to Tx and Rx to Rx spacings, and
minimum Tx to Rx separations must be strictly maintained. For information
on ACCP operation and limitations contact Aviat Networks or your supplier.
IRU 600 Variants
There are three variants, IRU 600 [IRU 600(v1)], IRU 600v2, and IRU 600v3. IRU
600v2 and IRU 600v3 incorporate a transmit coaxial RF switch in place of the Tx
coupler used with IRU 600(v1) for 1+1 hot standby and space diversity applications.
IRU 600v2 and IRU 600v3 also add a transmit monitoring port.
Tx Coaxial Switch: IRU 600v2 and IRU 600v3
Primary benefits of the Tx coaxial switch are reduced power loss and faster Tx pro-
tection switch times.
l It avoids the losses associated with a Tx coupler/combiner.
o
With the Tx coaxial switch (relay) there is no A-side versus B-side
consideration required as the loss is not more than 0.5 dB on both.
