Optical Tunable Filters
Thermally Tunable FBG Filter – 0.07nm Linewidth, 2nm Tuning
The TTFG series tunable optical filter integrates a fiber Bragg grating (FBG) with a thermally controlled tuning platform to provide narrow-linewidth filtering with wide center-wavelength adjustability. Two configurations are available: a two-port reflection version that functions as a tunable notch filter, and a three-port transmission-reflection version with an integrated circulator that operates as a tunable bandpass filter. Standard FBG linewidths are offered from 0.07 nm to 2 nm, with narrower custom designs available. Our circulators cover 350–2200 nm, enabling broad system compatibility for three-port TTFG solutions. The module includes an integrated driver with USB GUI control for plug-and-play operation, along with a DC power supply.

System integration
Integration and compatibility
Use these checks to connect Thermally Tunable FBG Filter – 0.07nm Linewidth, 2nm Tuning to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optical interface and fiber
- Fiber Type: SMF-28, PM1550, PM1310, SM980 · Fiber Cover: 900um tube
- 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 and loss budget
- Wavelength: 1550.5nm, 950.8nm, 1061.5nm
- 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.
