Optical Tunable Filters
Our ITU Channel Tunable Filter provides computer-selectable wavelength passband control over telecom ITU grid channels through a USB/RS232 interface with a user-friendly GUI. Configurations are available for up to 22 CWDM channels, 80 DWDM channels at 100 GHz spacing, and 96 DWDM channels at 50 GHz spacing. The design employs passive WDM components to ensure excellent channel accuracy, low distortion, and high-fidelity spectral profiles.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
ITU Channel Tunable Filter SWDM, CWDM, WDM (100GHz), DWDM (50GHz): Laboratory optical integration depends on preserving the optical budget through the complete path. The CWDM, WDM100GHz, DWDM50GHz wavelength specification sets source and detector compatibility. The fiber/interface entry (SMF-28) must match the connected components.

Technical FAQ
Fiber Type: SMF-28 · Fiber Cover: 900um loose tube, Special. Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
Wavelength Spacing: CWDM, WDM100GHz, DWDM50GHz. Check the Optical Tunable Filters passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
