JDS Uniphase TB9 JDSU TB9226-1SP1 Tunable Grating Filter 1460-1575nm

The JDS Uniphase TB9226-1SP1 is a tunable grating filter engineered for dynamic wavelength selection and optical signal conditioning across the C-band and extended L-band. Built on diffraction grating technology, it delivers superior wavelength isolation and narrower passbands compared to Fabry-Perot and interference filter alternatives. The instrument operates as a precision spectral filter for single-mode fiber systems in laboratory and production test environments.
