  • Standalone four-channel QAM modulator with IP (TS-over-IP) inputs and RF output agile over the VHF and UHF band
  • Power-over-Ethernet support: No separate power feed required
  • Supports IP de-encapsulation and 2D FEC decoding according to SMPTE 2022-1/2
  • Removal of IP jitter with programmable size of jitter-tolerance buffer
  • LCD status display shows device identifier, bitrate, IP/MAC address and status


  • Small-scale CATV networks
  • Cable-network simulator
  • QAM test-signal generator

Powering Options

  • Through the Ethernet cable using:
    - IEEE 802.3af compatible PoE switch
    - PoE midspan power inserter
  • With DTE-PWR2 power adapter

Hardware Limitations

  • Channels must be grouped: overall spectrum of the DTE-3114 cannot be wider than 32MHz
  • All channels must operate in the same mode and with the same symbol rate
  • Not supported:
    - Scrambling of incoming Transport Streams
    - VBR input streams
    - SPTS-to-MPTS multiplexing
     (possible in software with MuxXpert)
