Optical receivers series SN1500

  • High output level 126 dBuV
  • Wide range of input optical power
  • Multistage correction of AFC
  • Output signal can be divided by insertion modules of splitter or tap
  • Current transit of remote feeding over all ports is 6 A
  • Displaying the input optical power (-10…+3 dBm)
  • Input and interstage level and splope control
  • Multilevel protection of output stages

The receiver is intended for transforming of optical signals received from an optical transmitter to radio frequency signals in hybrid CATV networks.
