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.
Optical Fiber Filter WDM FTTX 1625nm FS-FWDM-1625 is made by special optical components and advanced technology, it can deeply let 1600-1670nm wavelength pass but efficiently stop 1250-1590nm wavelength. This product is mainly used in optical fiber on-line testing. It is ideal component of 1625/1650nm optical fiber filtering.
