In-Line Attenuators

In-Line Attenuators

The In-Line attenuators provide a fixed level of attenuation and feature excellent return loss. Low cost and performance determine them for universal using in optical networks.

  • Return loss > 50 dB
  • Insertion loss on customer´s demands
  • Fiber or cable version
  • Pigtail with connector by specification
