JDSU TB9 Optical Attenuator

Features: Tuning Range from 1525-1625 nm Single-Mode Fiber In and Out Grating-based Optical Filter Full width at half maximum (FWHM) as low as 0.22 nm Parallel and serial interfaces High Rejection GPIB and RS232 Remote Control Applications Spontaneous emission suppression Tunable laser based testing ASE filtering in EDFAs WDM and DWDM component testing The JDS Uniphase Tunable Grating Filter is designed for highperformance laboratory and production testing of single-mode fiber-based components and subsystems. It features fine adjustment with resolution of 0.01 nm, and narrow passbands are available from 0.22-1.4 nm. The filter attains much higher wavelength isolation roll-off than Fabry-Perot etalons or interference filters. The filter can be used for amplified spontaneous emission (ASE) filtering in erbium-doped fiber amplifier (EDFA) applications or to remove spontaneous emission from distributed feedback lasers (DFBs) and tunable lasers in measurements of wavelength selective components. Both single and double pass grating configurations are available to provide high rejection and narrow bandwidth. Six standard models are available with different bandwidths and optical performance for specific applications. The Tunable Grating Filters can be controlled from the front panel keypad or by the GPIB and RS232 interfaces.
