Benefits:

  • cooled DFB laser
  • laser thermostabilization system  
  • measuring of level of input HF signal
  • possibility of manual or automatic  adjustment of HF level
  • AGC system providing the fixed output power of a laser
  • Wide spectra of choice of output optical power
  • precorrector of nonlinear distortions
  • all parameters are programmatically controlled  through CMH data bus
  • integrated display and keyboard for control
  • sockets:

    HF input and test- F socket
    optical - SC/APC
    additional ports of CMH data bus - 4P4C
