EXFO’s optical filters are wavelength tunable and bandwidth adjustable. They will provide you with superior performance whatever your application or goal.
The use of bulk optics in combination with diffraction gratings leads to high selectivity, low insertion losses and dispersion.
EXFO’s tunable filters are perfect tools for numerous studies and applications such as channel selection for bit error rate testing, analysis of sub-band of complex modulation formats, new modulation formats (40 Gbit/s and 100 Gbit/s), channel spacing reduction, WDM-PON, DWDM systems testing, amplification analysis, cascaded ROADM emulation, OFDM, active component and module testing, transponders testing and more.
EXFO offers a complete portfolio of tunable filters, including:
XTA-50: automatic ultra-selective filters with narrow bandwidth
XFA: automatic ultra-selective filters with fixed narrow bandwidth
XTM-50: manual ultra-selective filters with narrow bandwidth
