Variable optical attenuator

These VOAs can be used to to precisely balance the signal strengths in fiber circuits or to balance an optical signal when evaluating the dynamic . In addition, we offer electronic VOAs that provide manual or electronic control of the output power. The optical fiber built into each device is single mode over the specified operating wavelength range. These optical attenuators use an ultra-stable and reliable single-axis MEMS mirror to reflect the light that is collected and collimated from the input fiber to direct it to the output fiber.

These operate by collecting and collimating light from an input fiber and then reflecting this light off of an ultra- stable and reliable, single-axis DiCon MEMS mirror.

The reflected light is directed to the .

All of our attenuators operate over the two standard wavelength bands, the C-Band and the L-Band.

This wide wavelength range makes these components ideal for DWDM applications. VOA Variable Optical Attenuator. An abbreviation for variable optical attenuator.

Handheld Automated Variable Fiber Optic Attenuator , High Precision with Digital Display and Remote Control. This attenuator controls the attenuation by increasing the air gap distance between the two connectors, which decreases the coupling efficiency. Single-crystal silicon is an ideal material for miniature mechanical devices.

Silicon is inexpensive and has virtually no hysteresis and hence almost no energy dissipation, as well as little fatigue to ensure service lifetimes over trillions of flexing cycles without breaking. The lightweight and thin format enables optic devices . These VOAs are designed to meet the most mission-critical high speed optical switching applications. Optical attenuators are devices which can reduce the optical power e. These attenuators are designed to meet Telcordia standards. Depending on the specific application, the VOAs may be set to maintain an electronically . They are available in single wavelength and dual wavelength.
