Optical Fibre Attenuator

The Optical Fibre Attenuator product has the function of fixed attenuator value of 2dB to 15dB, which provides fixed attenuation for the communication system, so that the communication system can achieve the appropriate output power.
Applications
  • Optical distribution frame
  • Optical network system
  • High-speed optical fibre transmission system
  • Cable TV (CATV) system
  • Long-distance trunk line dense wavelength division multiplexing (DWDM) system
  • Optical add / drop Multiplexer (OADM)
  • High power optical device measurement
Characteristics
  • Selectable diversification of attenuation values (2 dB,3 dB,5 dB,7 dB,10 dB,15 dB)
  • Cover communication band 1260nm - 1625nm
  • Plug structure for easy installation
  • Diverse plug types
  • Precision attenuation value and high return loss
  • Meet or Exceed GR-1221-CORE, GR-1209-CORE, GR-468-CORE standard specification
