Band Pass & Edge Filters

Band-pass and edge thin-film filters are housed in 3-port packages. They are designed for tri-band WDM, CWDM and DWDM on 50, 100 or 200 GHz channel spacing. They are also available to multiplex 980 nm or 14xx nm pump laser wavelengths with a DWDM signal within optical amplifiers. The thin-film filters achieve high center frequency stability over the entire operating temperature range.


  • Low insertion loss
