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 Fiber Filter WDM FTTX 1490nm FS-FWDM-1490 can select 1490nm(1490nm)we research and develop based on the development of optical communication needs. Because we adopt special filter elements and unique production processes, It can let 1490nm (1490nm) wavelengths pass efficiently, depth of cut-off 1310nm(1300nm),1550nm,1625nm and 1650nm wavelength light function. Use our optical filter which can get a ideal filtering function.
