Directly modulated transmitter 1550 nm - Typ AT-51-DMOD-06, AT-51-DMOD-10

The 1550 nm direct modulated (DMOD) laser transmitters of the AT5100 series offer a flexible and scalable solution for the optical transmission of high-quality video signals in CATV networks over short and medium distances. The transmitters are equipped with a DFB laser with high linearity and low wavelength deviation (chirp). The high performance is also achieved through integrated compensation of pre-distortion and AGC control.

  • FTTH applications over short and medium distances
  • Long-distance transmission for QAM overlay applications up to 70 km
  • Transmission of analog and digital signals up to 15 km
  • Transmission of digital signals up to 40 km
  • DFB laser with high linearity and low wavelength deviation (chirp)
  • Built-in pre-distortion compensation and AGC control
  • Two redundant, hot-swappable AC power supplies (DC on request)
  • Suppression of stimulated Brillouin scattering (SBS) for optimized intermodulation behavior (CSO)
  • LC display for local monitoring on the device
  • Local and remote access for monitoring and configuration
  • SNMP/HTTP monitoring, configuration and control

    Headline

    The distribution of satellite signals via fibre optic cable offers decisive technical and economic advantages, especially for larger distances / distribution networks and a wide variety of programmes. In addition to the high data capacity and virtually loss-free signal transmission, the fast installation and reliability of pre-assembled fibre optic cables play a decisive role.
    The POLYTRON system works with conventional LNBs and utilises proven CWDM technology for signal transmission.
