FOA is a plug-type single mode attenuator (multimode fiber attenuators also available). It is used directly on the fiber optic connectors and provides a fixed level of optical attenuation. It has low return loss and works at both 1310nm and 1550nm wavelength range (850nm or 1300nm for multimode fiber). FC and SC connector types with PC or APC polish are available, as well as ST and LC types of attenuators.

In addition to standard 1~25dB attenuation, we also provide FOA with high attenuation of 35dB.

Features:

  • Good repeatability
  • High precision
  • High return loss
  • Small size
  • Good directivity
  • FC, SC, ST and LC types available
  • High attenuation (35dB) available

Application:

  • Fiber communication
  • Fiber CATV
  • LAN
  • Test equipment
