Variable Optical Attenuators
MEMS Broadband Optical Attenuator – Fiber-Fiber™
The Fiber-Fiber™ series VOA is based on fiber-to-fiber direct coupling with a micro-electro-mechanical (MEMS) shutter in between. It eliminates the need for lens and optical coating, featuring low loss, ultra-broadband without altering fiber transmission character, high power, compact size, and easy drive. The current MEMS chips accommodate fiber with 3 to 105 mm core diameters. VOAs with fiber of larger diameters can be made with special chip fabrication run with an NRE charge. The Fiber-Fiber™ series VOA is compliant with the Telcordia 1209 and 1221 reliability standards. The VOA is driven by directly applying a low electrical voltage. The VOA is electrically a resistor load, has no polarity, and is electrostatically insensitive.

- 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 Range: 405 – 532 nm / 480 – 650 nm / 620 – 650 nm / 760 – 800 nm / 830 – 870 nm / 980 – 1550 nm / 960 – 1080 nm / 1020 – 1900 nm / 1.7 – 2.3 µm · Insertion Loss: <1 dB / <1 dB / ≤0.8 dB / ≤0.6 dB / ≤0.5 dB / ≤0.5 dB / ≤0.4 dB / ≤0.2 dB / ≤0.5 dB
