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
