What is the maximum recommended fiber connection loss?

The idea here is how much loss a single fiber connection should be allowed to contribute to the link budget. Each physical connection adds some insertion loss, and standards set a practical ceiling to keep the total budget realistic for real-world terminations and field workmanship. The commonly recommended maximum per connection is 0.75 dB, which accounts for typical connector performance and the variability seen in field terminations. Staying at or below this value helps ensure the overall link length and data rate can meet the required performance with an adequate margin. Loss values like 1.5 dB or 2.0 dB per connection would quickly consume the budget for multi-connection links, while 0.25 dB is optimistic given real-world connectors.
