Polarization Bandpass Filter
The polarization bandpass filter is based on thin-film filter technology, allowing specific wavelength bands to pass while blocking other wavelengths. It uses high-performance thin-film filter chips and high-quality optical fibers, ensuring stable and reliable performance. This optical fiber polarization bandpass filter is extremely flat in the passband, with almost no insertion loss or polarization dependence within the passband. It is widely used in EDFA and optical fiber laser systems to suppress noise, featuring high isolation, low insertion loss, and high power handling capabilities.
