Product brief introduction：
CATV modulator chip is using microfabrication technology in lithium niobate wafer produced, waveguide in X cut Y lithium niobate wafer using annealed proton exchange process, can be in the 200MW optical power under normal operation, two light output to provide a flat electro-optic response and excellent two order composite distortion index ( CSO ).
• 1550 nm Window
• 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
The SWT dual output analog community antenna television (CATV) modulator is
based on a Mach-Zehnder waveguide interferometer and is manufactured using the
annealed proton exchanged in X-cut, Y-propagating LiNbO3 substrates, it is rated for
operation at optical power levels to 200mW. Two optical outputs offer flat electrical
frequency response and excellent composite second order distortion(CSO).
• High Performance External Intensity Modulation for 1550 nm CATV Band Transmitters
