JDSU MAPF+1GG001SU Tunable Filter TB3

The JDSU MAPF+1GG001SU Tunable Filter TB3 is a tunable grating filter module engineered for precision optical test and measurement applications. This bandpass filter enables continuous wavelength selection across the C-band and L-band regions, delivering narrow optical bandwidth with low insertion loss and high out-of-band rejection. It suppresses amplified spontaneous emissions, isolates specific wavelengths, and supports critical measurements including OSNR analysis, BER testing, and amplifier characterization.
