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.
