The JDSU Tunable Filter (mTBF-A1) / MTBF-A1CH0 is a tunable bandpass filter engineered for precise wavelength selection in optical systems. It isolates specific wavelengths, suppresses amplified spontaneous emissions (ASE), and enables precise spectral control across the C-band and extended L-band. The filter integrates into the MAP-200 platform—an LXI Class C compliant system—and supports hot-swappable cassette installation without system shutdown. Its high tuning resolution and low insertion loss make it ideal for optical communications testing, amplifier characterization, BER measurement, and OSNR analysis.
