Microwave links DML


The DML series of Digital Microwave Links for fixed and mobile applications represent the latest development based on ABE digital and microwave technological knowledge and experience, accumulated with thousands of units produced since 1982.

These are agile synthesized Digital Links (also usable with analog signals), extremely compact, flexible and competitively priced.


Key Features

  • Capable to carry up to #6 different MPEG Transport Streams
  • Transparent mode to carry SFN Transport Streams (including ISDB-T/Tb BTS)
  • Over 100Mbit/s total net bit rate in 28MHz RF bandwidth
  • Frequency Agile in its range (typically 500MHz)
  • Several frequency range available (2, 6, 7, 8, 10, 13, 14 GHz - other on request)
  • Modulation schemes supported: DVB-S/S2 or OFDM (DVB standard)
  • Fixed (STL) and portable applications
  • RF heads for outdoor and indoor applications
  • Standard input/output interface: ASI - On request: Ethernet for T.S. over IP
  • Analog Video/Audio in/out interfaces (versions with embedded MPEG codecs)


Main Benefits

  • NO proprietary modulation schemes and FEC codes (DVB-S2 modulation schemes up to 32APSK employed)
  • NO proprietary aggregation systems - The aggregation of the Transport Streams (up to #6) is made employing the DVB-S2 MULTISTREAM mode
  • NO proprietary encryption: DVB-S2 Physical Layer scrambling implemented
  • NO overhead for encapsulation to carry multiple Transport Streams
  • Very high efficiency Forward Error Correction Codes (LDPC + BCH)
  • NO fixed capacity: parameters (bandwidth, FEC codes, etc.) are optimized in order to obtain the best performance according to the available bandwidth and needed capacity
