Optical Fiber Bandpass Filter(BPF) WDM FTTX 1550nm
The optical filter is an instrument that is used for wavelength selection, which can select required wavelengths from a large number of wavelengths and reject the addition wavelengths. It can used in wavelength selection, the noise filter of the optical amplifier, gain equalization, optical multiplexing /demultiplexing.
Our Optical Optical Fiber Bandpass Filter(BPF) WDM FTTX 1550nm FM-FWDM-1550-BPF is based on proven thin-film filter technology. This BPF is widely used in fiber optical communication systems and EDFA where flat and broad operating bands are needed.
