Variable Optical Attenuators
Manual No-Gap Broadband Variable Fiber Optical Attenuator — Low-Loss
The Fiber-Fiber™ Series Manual Variable Optical Attenuator (VOA) delivers industry-leading performance with ultra-low insertion loss and continuous, perturbation-free light transmission. Its ultra-broadband operation is limited only by the transmission characteristics of the optical fiber, enabling exceptionally wide wavelength coverage. The patented Fiber-Fiber™ technology utilizes direct fiber-to-fiber coupling through a self-aligned MEMS platform. A microscopic gap of less than 5 μm between the fiber end faces is filled with a proprietary non-fluorescent, index-matching liquid, creating a nearly lossless optical path without the need for lenses, collimators, or anti-reflection coatings. This unique architecture virtually eliminates Fresnel reflections and minimizes insertion loss while maintaining excellent optical fidelity.

System integration
Integration and compatibility
Use these checks to connect Manual No-Gap Broadband Variable Fiber Optical Attenuator — Low-Loss 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: SM28, SM28e, Corning XB, SM400, SM450, SM600, Hi780, SM800, Hi980, Hi1060, SM1950, PM350, PM400, PM405, PM460, PM480, PM630, PM780, PM850, PM980, PM1310, PM1550, PM1950, GIF50, GIF625, 105/125, FG50LGA, FG105LCA, FG10LDA · 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
- Test Wavelength: 350, 488, 532, 630, 780, 850, 980, 1060, 1310, 1550, 2000
- Check the Variable Optical Attenuators 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.
