Product Specification Sheet
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
