Product Description:

With BPI's unique opto-mechanical design and advanced packaging techniques,  the filters demonstrate extreme wavelength stability under varied environmental  conditions temperature and humidity.    

By a patented precision tuning techniques, the filters come with an  option of ITU targeting accuracy within +/-1.25GHz. This ITU-targeted filter is widely used in WDM system channel monitoring and wavelength blocking. The special option is also available for customer to select specific wavelength  for precision targeting.
