Safety Precautions & Declared Material
General Equipment Precautions
Use of controls, adjustments, or performing procedures other than those
specified herein, may result in hazardous radiation exposure.
When working with a FibeAir IDU, note the following risk of electric
shock and energy hazard: Disconnecting one power supply disconnects
only one power supply module. To isolate the unit completely,
disconnect all power supplies.
Machine noise information order - 3. GPSGV, the highest sound pressure
level amounts to 70 dB (A) or less, in accordance with ISO EN 7779.
Static electricity may cause body harm, as well as harm to electronic
components inside the device.
Anyone responsible for the installation or maintenance of the FibeAir RFU-C
must use an ESD Wrist Strap.
ESD protection measures must be observed when touching the RFU.
To prevent damage, before touching components inside the device, all
electrostatic must be discharged from both personnel and tools.
In Norway and Sweden:
Equipment connected to the protective earthing of the building installation
through the mains connection or through other equipment with a connection
to protective earthing –and to a cable distribution system using coaxial cable,
may in some circumstances create a fire hazard. Connection to a cable
distribution system has therefore to be provided through a device providing
electrical isolation below a certain frequency range (galvanic isolator, see EN
60728-11).
Utstyr som er koplet til beskyttelsesjord via nettplugg og/eller via annet
jordtilkoplet utstyr –og er tilkoplet et kabel-TV nett, kan forårsake brannfare.
For å unngå dette skal det ved tilkopling av utstyret til kabel-TV nettet
installeres en galvanisk isolator mellom utstyret og kabel- TV nettet.
Utrustning som är kopplad till skyddsjord via jordat vägguttag och/eller via
annan utrustning och samtidigt är kopplad till kabel-TV nät kan i vissa fall
medfőra risk főr brand. Főr att undvika detta skall vid anslutning av
utrustningen till kabel-TV nät galvanisk isolator finnas mellan utrustningen
och kabel-TV nätet.

Précautions générales relatives à l'équipement
L’utilisation de commandes ou de réglages ou l'exécution de procédures
autres que celles spécifiées dans les présentes peut engendrer une
exposition dangereuse aux rayonnements.
L’usage de FibeAir IDU s’accompagne du risque suivant d'électrocution
et de danger électrique : le débranchement d'une alimentation
électrique ne déconnecte qu'un module d'alimentation électrique. Pour
isoler complètement l'unité, il faut débrancher toutes les alimentations
électriques.
Bruit de machine d’ordre - 3. GPSGV, le plus haut niveau de pression
sonore s'élève à 70 dB (A) au maximum, dans le respect de la norme ISO
EN 7779.
Allgemeine Vorsichtsmaßnahmen für die Anlage
Wenn andere Steuerelemente verwendet, Einstellungen vorgenommen
oder Verfahren durchgeführt werden als die hier angegebenen, kann
dies gefährliche Strahlung verursachen.
Beachten Sie beim Arbeiten mit FibeAir IDU das folgende Stromschlag-
und Gefahrenrisiko: Durch Abtrennen einer Stromquelle wird nur ein
Stromversorgungsmodul abgetrennt. Um die Einheit vollständig zu
isolieren, trennen Sie alle Stromversorgungen ab.
Maschinenlärminformations-Verordnung - 3. GPSGV, der höchste
Schalldruckpegel beträgt 70 dB(A) oder weniger gemäß EN ISO 7779.

3. RFU-C Overview
RFU-C is a state-of-the-art Radio Frequency Unit which is fully software
configurable and supports a broad range of capacities and interfaces.
The RFU supports low to high capacities for traditional voice and Ethernet
services, as well as PDH/SDH/SONET or hybrid Ethernet and TDM interfaces.
This innovative platform uses an “on-the-fly” upgrade method, whereby
network operators only buy capacity as needed, benefiting from savings on
initial investments and OPEX.
Traffic capacity throughput and spectral efficiency are optimized with the
desired channel bandwidth. For maximum user choice flexibility, channel
bandwidths can be selected together with a range of modulations of from
QPSK to 256 QAM.
High spectral efficiency is ensured using the same bandwidth for double the
capacity, via two carriers, with vertical and horizontal polarizations. This
feature is implemented by a built-in XPIC mechanism.
RFU-C works together with several types of indoor units (IDUs). For
PDH/SDH/SONET, the RFU works with the FibeAir 1500R IDU. For Ethernet
and TDM to Ethernet migration, RFU-C works with the FibeAir IP-10G IDU. For
Ethernet only, RFU-C works with the FibeAir IP-10E and FibeAir IP-10Q IDUs.
Together, FibeAir RFU-C and FibeAir IDUs provide a powerful, reliable, and
comprehensive solution for a variety of wireless network scenarios and
requirements.
When RFU-C operates in co-channel dual polarization (CCDP) mode, using the
cross polarization interference canceller (XPIC) algorithm, two carrier signals
can be transmitted over a single channel, using vertical and horizontal
polarization. This enables double capacity in the same spectrum bandwidth.

4. Installing an RFU-C
This section describes the basic types of RFU-C installation.
4.1 Packing
The equipment should be packed and sealed with moisture absorbing bags.
4.2 Transportation
The equipment should be prepared for public transportation. The cargo must
be kept dry during transportation, in accordance with ETS 300 019-1-2, Class
2.3.
It is recommended that the equipment be transported to the installation site
in its original packing case.
If intermediate storing is required, the packed equipment must be stored in a
dry and cool environment, and out of direct sunlight, in accordance with ETS
300 019-1-1, Class 1.2.
4.3 Inspection
Check the packing lists and verify that the correct equipment part numbers
and quantities are found in the packages that arrived.
