FC Flange attenuator

SKU 3299052211ef Categories ,

The male-female attenuator is connected to a fiber optic connector at one end and
a fiber optic adapter at the other end. Its attenuation is fixed,unadjustable.this range
of fixed attenuator is mainly used to reduce optical power to target value in optical
links. the attenuation value is in range of 0 to 30dB, which are all applicable for
optical signal with wavelength ranging from 1250nm to 1600nm.

  • Excellent Changeability and Directivity

  • Accurate attenuation
  • Max operation power (0.5W)
  • Low polarization related loss
  • Individual package available
  • Standard sleeve,Various adaptor option: LC、SC、FC、ST、MU etc.
