The ideal (minimum-loss) fiber path would have NO connections. Instead, it would be one continuous, straight-through glass fiber from Point A to Point B – with no interruptions. Since fiber networks usually require connectors for modularity, path splits, etc., we need a connection with perfectly aligned, intimate “glass to glass” contact that emulates the continuous fiber and gives us the desired Low IL and High RL.

When this perfectly aligned, intimate “glass to glass” contact is not achieved, reduced IL/RL performance is the result. Briefly, here are some common causes.

  1. End-face quality and cleanliness
  2. Misalignment between the 2 cores
  3. Poor core-to-core contact
