OMU II
Optical Master Unit
Key features:
Supports Cellular 2G, 3G, 4G services up to 2700MHz & public
safety services FM/VHF/UHF/LMR on the same enclosure
Single enclosure to support high power (MBF-40) and low
power (MBF-20) remote units
MIMO support
Web based remote management via wireless modem
Flexible configuration to support up to 8 sectors via single chassis
Simple integration to AEM or any other 3rd party NOC via SNMP traps
The OMU II is used to convert signals
from RF to light when fibre-fed
repeaters are used at the remote
end of the optical link. The OMU II is
a headend system that can be
connected directly to a base station
or off-air device such as a digital
repeater or bi-directional amplifier.
For larger venues with multiple
services and multiple bands, a Point
Of Interface (POI) unit may be
required to condition Uplink and
Downlink RF signals between the
BTS/Off-air Repeater and the OMU.
In the downlink direction, the OMU
picks up the signal from the BTS,
converts it into an optical signal and
transfers it over a fibre optical cable
to the repeater. In the uplink
direction, the OMU receives the
signal from the remote repeater via
the fibre optical cable, converts it to
a RF signal and sends it back to the
base station.
Architecture
Each OMU II has a dedicated control
card, alarm and battery backup card,
rack communication board (RCB),
optional modem card and 2 AC/DC
power supplies on the back of the
chassis. It has 12 slots in the front to
support the Opto Module cards and
Signal Conditioning Card- Optical
Splitter Module (OSM). The OSM
cards include a 1:4 optical splitter
hence it can support up to 4 MBF-20
units from a single OSM.
The OMU II can support up to 8 of
our standard high powered MBF-40
or 24 low powered MBF-20
remotes. For the maximum number
on MBF-20 remote units, 6 Opto
Modules and 6 OSM are used which
may be configured according to the
number of sectors used in the
project – up to 6 sectors in this
configuration. If only MBF-40 units
are required, up to 8 Opto Module
cards are used (no OSM cards) which
may be configured according to the
number of sectors used in the
project – up to 8 sectors in this
configuration. You can mix and
match between the MBF-40 and MBF
20 remote units. Please refer to the
2nd page for all the available
options.
Automatic Optical Gain Setting
The fibre optic system Axell Wireless
has designed puts a clear focus on
user friendliness and ease of
installation and commissioning.
Through an automatic optical gain
setting, the commissioning is easily
performed, thus reducing the time it
takes to put the equipment in
service. This also means that the
training is significantly simplified and
the need for installation effort is
decreased.
Remote Supervision
Only one modem is needed to
communicate with an OMU II and its
fibre fed repeaters. The modem
types available are GSM, UMTS,
CDMA 1x, PSTN, and TCP/IP. The
modem is found inside the OMU II
and communication with the fibre-
fed remote units is transparently
handled via the fibre that connects
them. The system can be monitored
and controlled via the Axell Wireless’
network management software tool
called AEM. AEM communicates with
each fibre remote unit via the OMU
over the same single mode fibre
strand that carries the RF signals.
Both data communications and the
RF signals are managed over the
same fibre link which results in a very
reliable supervision of the radio link.
The OMU Mark II supports: public
safety services (VHF, UHF, TETRA,
SMR 700/800/900), cellular bands for
EMEA and APAC (800 / 900 / 1800 /
2100 / 2600) and LTE700, 850, PCS
and AWS for Americas and is always
used in combination with one or
several fibre fed repeaters.
