Specifications

   Description:
  • The FC/UPC Variable Optical Attenuator is a manually adjustable passive device designed to finely control the power level of an optical signal in single-mode fiber networks. Equipped with an FC connector (threaded coupling) and Ultra Physical Contact (UPC) polish, this VOA offers high stability, low return loss, and precise attenuation for field, lab, and network applications. It is ideal for simulating distance or loss, testing receivers, and equalizing optical signal strength in real time.
   Features:
  • Variable Attenuation Range: 0 to 30 dB (manual adjustment)
  • Connector Type: FC/UPC (threaded for stable, repeatable connections)
  • Polish Type: UPC (Ultra Physical Contact) for low reflectance
  • Operating Wavelengths: 1260–1650 nm
  • Return Loss: = 55 dB (UPC)
  • Insertion Loss: = 0.5 dB (excluding intentional attenuation)
  • Precision Adjustment: Thumb screw or dial for smooth attenuation control
  • Durability: =1000 mating cycles
  • Compliance: RoHS compliant and dust-cap protected
   Specifications:
  • Attenuation Range: 0 to 30 dB (variable)
  • Connector Type: FC/UPC
  • Wavelength Range: 1260 nm – 1650 nm
  • Return Loss: = 55 dB
  • Insertion Loss: = 0.5 dB (excluding attenuation)
  • Max Optical Input Power: = 300 mW
  • Operating Temperature: -40°C to +75°C
  • Storage Temperature: -40°C to +85°C
  • Fiber Compatibility: Single-mode fiber (SMF-28 or similar)
   Ideal Use Cases:
  • Laboratory Testing: Simulate loss to validate receiver sensitivity or system margins
  • Telecom Networks: Protect optical receivers by fine-tuning power at the input
  • Field Deployment: Adjust signal power for real-world link balancing
  • DWDM/CWDM Systems: Control individual channel power levels to reduce interference
  • Fiber Optic Training/Simulation: Demonstrate attenuation effects for educational purposes
   Why Choose the FC/UPC Variable Attenuator?
  • Secure Connection: Threaded FC interface ensures consistent, vibration-resistant contact
  • Adjustable Attenuation: Enables on-the-fly signal control without replacing components
  • Low Reflectivity: UPC polishing minimizes back reflection, ensuring signal integrity
  • Versatile Design: Suitable for temporary testing or permanent inline adjustment
  • Accurate Performance: High repeatability with minimal insertion loss
