CATV Modulator

Product Description: 

The dual output analog community antenna television (CATV) modulator is based on a Mach-Zehnder waveguide interferometer using the annealed proton exchanged in X-cut, Y-propagating LiNbO3 substrates. Two optical outputs offer flat frequency response and excellent composite second order distortion (CSO) performance.

Key Features:

  • APE Waveguide
  • Low Insertion Loss
  • Low Drive Voltage
  • Low Electrical Return Loss(S11)
  • Flat Frequency Response
  • Separate Bias Electrode
  • Dual Optical Output Ports
  • Enables Low CSO on Both Outputs
  • Integrated Phase Modulator

Applications:

  • High Performance External Intensity Modulation for 1550 nm CATV Band Transmitters
