POLYTRON Directly modulated transmitter 1550 nm AT-51-DMOD-10

POLYTRON Optische Sender AT-51-DMOD-06

Directly modulated transmitter 1550 nm

The AT5100 series of 1550 nm directly modulated (DMOD) laser transmitters 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 feature a DFB laser with high linearity and low wavelength deviation (chirp). The high performance is further enhanced by integrated pre-distortion compensation and AGC control.

 

 

  • FTTH applications over short and medium distances
  • Long-distance transmission in 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
