JDS Uniphase TB9 JDSU TB9226-FA Tunable Grating Filter 1460-1575nm

The JDS Uniphase TB9226-FA is a tunable grating filter engineered for precise wavelength selection across the S + C bands (1460–1575 nm). It delivers narrow-bandwidth optical filtering with grating-based rejection suitable for laboratory and production test environments where signal conditioning and wavelength selectivity are critical. This filter excels at ASE suppression in EDFA systems and removing spontaneous emissions from DFB and tunable laser sources during component characterization.

Wavelength tuning resolves to 0.01 nm with 0.2 nm setting accuracy and 0.05 nm repeatability. Narrow passband performance - 0.25 nm at −3 dB (FWHM) and 0.7 nm at −20 dB - enables high spectral purity across the tuning range.
