The Polarization Insensitive Isolator Core is a Faraday Rotator based component for in-line fiber optic isolator. It can also integrate with other components to block back reflection or to enhance component isolation. It is insensitive to the input beams polarization state and has high isolation, low insertion loss, low PDL and low PMD.
The PM FWDM series provides wavelength division multiplexing while maintaining signal polarization. This component is based on environmentally stable thin film filter technology and is characterized with high extinction ratio, low insertion loss, and high return loss. They are ideal for high speed WDM network systems.
The High Power N × 1 Laser Combiner is designed for combining the power from N units of kW class fiber laser with high efficiency. The laser combiner is available for different fiber types.
The 40G-Thin Film modulator design is based on a dual parallel structure of 2 Mach-Zehnder modulators embedded in a Mach-Zehnder super-structure. Each internal modulator is designed to have EO bandwidth above 20 GHz. Monitor photodiode is provided for automatic bias control.
AFR's Integrated Polarization Maintaining Tap Power Detector (PMTAPD) integrates the functionality of a optical coupler and a photodiode for optical network's power detection. It applys for channel power monitoring in DWDM system, in-line optical network switchingprotection monitoring(OLP), re-configurable optical add/drop multiplexer(OADM), and gain/attenuation monitoring in EDFA, etc.
