Manual Tunable Fiber Optical Filters– Etalon-Based

  • Compact and Low Cost
  • Wide Tune Range
  • Wide Wavelength Coverage
  • Low IL and PDL




Based on a proprietary thin film cavity filter technology, Photonwares offers Fiber Optic Tunable Filters with central wavelengths of 1060nm, 1310nm, 1550nm and 2000nm. It is tunable continuously over a wide spectral range up to 80 nm. The wavelength tuning is made by manually rotating a precise micrometer. Photonwares’s unique high reliability and low insertion loss design presents a most cost-effective solution for OEM applications from fiber optic networks to fiber sensing interrogation.
