The EXFO XTA-50 Tunable Filter is a precision tunable optical filter designed for DWDM, optical component, and system testing in R&D, validation, and manufacturing environments. Covering the C-band, the XTA-50 provides accurate wavelength selection, high out-of-band rejection, and stable optical performance for advanced photonics and telecom test applications.

With fine wavelength tuning and repeatable passband characteristics, the XTA-50 enables reliable channel selection, ASE noise filtering, and spectral shaping. Its high selectivity makes it ideal for OSNR measurements, receiver sensitivity testing, and DWDM channel isolation, even in dense channel spacing scenarios.

The XTA-50 supports remote control and SCPI automation, allowing seamless integration into automated optical test systems alongside tunable lasers, power meters, and optical spectrum analyzers. Its compact, rack-mountable design ensures easy deployment in both laboratory and production test setups.
