All specifications are subject to change without prior notice. 1    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.
