Tunable narrow-bandwidth filters

Tunable bandpass fiber-optic filters provide bandpasses of 0.5, 1 and 3 nm and tuning ranges from 1535 to 1565 nm. A 1-nm model with a 1290- to 1320-nm tuning range is also available. Applications include sideband noise suppression in erbium-doped fiber amplifiers and tunable laser transmission systems, as well as wavelength selection for test and measurement. The filters feature a tuning resolution of 0.05 nm, a typical loss of 1.5 dB and a maximum backreflection of -50 dB. Prices start at $1925.
