Tunable Bandpass Filter, 1550 nm, 9/125 µm, Pigtails, No Connectors

The TBF-1550-2.0 Tunable Bandpass Fiber Optic Filter is used to adjust the center wavelength of a narrow passband within a 30 nm range around 1550 nm.
A 0.6 nm tunable filter model is offered, having a 1535–1565 nm tuning range. The filter features high isolation, low insertion loss, low back-reflection and low polarization sensitivity.
A thin film coating interference filter, located between two angled fiber optic collimators, is used to select the wavelength of interest, by adjusting the tilt angle of the filter with a high-precision micrometer having 0.05 nm resolution.
Applications for Newport’s Tunable Bandpass Filter include: sideband noise suppression in erbium-doped fiber amplifiers (EDFA) and in tunable laser transmission systems; as well as wavelength selection for test and measurement applications.
