Most likely, your testing specifications present minimum requirements for a Low IL and High RL.

If your production facility is challenged with meeting the desired IL/RL specs, there are common causes you can investigate and address.

However, before addressing common causes of poor IL/RL, let’s quickly explain the terms:

  • Insertion Loss (IL) – The loss of signal power resulting from inserting a device in an optical fiber. This can be referred to as attenuation and is usually expressed as a ratio, in dB, relative to the input power.
  • Return Loss (also called Back Reflection) – The reflection of signal power, usually resulting from inserting a device (such as a connector or other component) in an optical fiber path. Again, this is usually expressed as a ratio, in dB, relative to the input power.
