PM High Power Optical Isolator + Optical Filter Hybrid
High-Power Polarization-Maintaining Optical Isolator and Optical Bandpass Filter integrated hybrid handling up to 20W optical power. Simultaneously blocks destructive back reflections (>30 dB isolation) and filters out ASE noise and Raman scattering in high-power PM fiber amplifiers.
