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.

– Compatibility & Integration
The TB3 module hot-swaps into JDSU MAP Series mainframes (MAP+2M00 and MAP+2B00 platforms) without system shutdown. The MAP-200 controller is LXI-compliant with Ethernet connectivity, GPIB, and RS-232 interfaces. Dynamic firmware automatically identifies installed cassettes and configures system operation.
