Mach-Zehnder Interferometer
NEL
PLC Mach-Zender interferometer- Planar lightwave circuits (PLCs) are based on silica waveguide technology and underpin the stability and reliability of the high-performance Mach-Zehnder interferometer.
Stable and reliable Mach-Zehnder interferometer based on silica-based planar lightwave circuit. It is suitable solution for the high-speed DPSK/DQPSK transmission systems.
FEATURE
FEATURE
- Fast optical frequency tracking by thermo-optic effect
- Low PDf (Polarization Dependent Frequency shift)
- Stable against mechanical vibration
- High reliability
- DPSK/DQPSK demodulation
- Time-domain optical pulse multiplexing
Thermo-Optic Switches
NEL
NEL's optical switches employ Mach-Zehnder interferometers with thermo-optic phase shifters as switching units and include an 8x8 optical matrix switch and an 8-arrayed 2x2 optical switch.
These switches are smaller and use less power than mechanical switches or O/E-SW-EO switches. These switches can be driven by +5V TTL-level voltage.
Main Features:
