GAO Tek’s fiber variable optical attenuators have the following functions:

  • Attenuation Control: The fundamental function of GAO’s VOA tester is to control the power level of an optical signal by introducing variable attenuation. It allows you to adjust the signal power according to your testing requirements. This function is essential for simulating various scenarios and assessing the performance of fiber optic networks under different power levels. 
  • Power Measurement: Our fiber variable optical attenuators include power measurement capabilities. They enable you to measure and monitor the optical power level before and after attenuation. 
  • Testing and Characterization: GAO’s fiber variable optical attenuators can be used to perform various tests and characterization tasks on fiber optic networks. 
  • Configuration and Control: Our fiber variable optical attenuators provide configuration and control options to customize the testing parameters and settings. This allows users to set attenuation values, select wavelengths, adjust power levels, and configure other test parameters based on specific testing requirements. 

GAO Tek’s fiber variable optical attenuators are rugged, versatile, and precision measurement instruments. They comply with applicable industry standards such as international electrotechnical commission (IEC) standards, telecommunications industry association (TIA) standards, and telecommunications standards development society.  

Our fiber variable optical attenuators help our customers comply with relevant US government regulations such as: 

  • Federal Communications Commission (FCC) Regulations 
  • Occupational Safety and Health Administration (OSHA) Regulations
  • Environmental Regulations 
  • Export Control Regulations 

Our fiber variable optical attenuators help our clients in complying with relevant Canadian government regulations such as: 

  • Innovation, Science, and Economic Development Canada (ISED) Regulations. 
  • Canadian Environmental Protection Act (CEPA) 
  • Waste Electrical and Electronic Equipment (WEEE) Regulations 
  • Export Control Regulations 

Our fiber variable optical attenuators have the following applications: 

  • Network Characterization: GAO’s VOA fiber variable optical attenuators are used to characterize the performance of fiber optic networks. By adjusting the attenuation levels, VOA testers simulate different power conditions, allowing technicians to assess the network's response under varying signal power levels. This helps identify potential issues, such as signal degradation, power imbalances, or sensitivity to power fluctuations. 
  • System Calibration: Our fiber variable optical attenuators can be used in calibrating fiber optic systems. They enable technicians to set precise power levels and validate the accuracy of power measurements throughout the network. This ensures that the system operates within the desired power range and helps maintain reliable and consistent signal transmission. 
  • Power Management: Our fiber variable optical attenuators are employed for power management purposes in fiber optic networks. They allow technicians to adjust the signal power to optimize performance, mitigate signal distortion, and maintain the power levels within the desired range. This is particularly important in long-haul transmission systems or networks with multiple components and connectors. 
  • Component Testing: GAO’s fiber variable optical attenuators are used to test and evaluate individual fiber optic components, such as connectors, couplers, or splitters. By adjusting the attenuation, technicians can measure the insertion loss, reflectance, and other performance parameters of these components. This helps ensure their quality, reliability, and compliance with industry standards. 
  • Link Loss Measurement: GAO’s fiber variable optical attenuators assist in measuring link loss or attenuation between two points in a fiber optic link. By adjusting the attenuation levels, technicians can measure the loss accurately and identify any potential issues, such as high loss points, faulty splices, or damaged fibers. This information is essential for troubleshooting and optimizing the performance of the fiber optic link.

Our fiber variable optical attenuators can be shipped overnight within the continental U.S. and Canada, and can be shipped globally.
