Fiber Link Loss Budget Calculator
Combine fiber attenuation, connectors, splices and safety margin against an optical power budget.
Result
Ready. Add input or load the example.
Use equipment-specific values and a consistent wavelength. This does not replace measured link testing.
What this tool does
Combine fiber attenuation, connectors, splices and safety margin against an optical power budget.
Worked example
Two km at 0.35 dB/km, two 0.5 dB connectors and two 0.1 dB splices total 1.9 dB before margin.
Prepare your input
Use the labelled controls below to enter your values or choose a local file. Load the example first if you want to see the expected input format. For imported tables, use a single header row and check the column names before running the operation. Keep an unchanged copy of your source data.
Review the result
Run the tool and inspect its on-screen findings before downloading. Validation errors identify input that needs correction; a successful export means the operation finished, not that the source information was independently verified. Copy a text result, download the prepared file or print the document where those controls are available. Reset clears this workspace.
Important limits
Use equipment-specific values and a consistent wavelength. This does not replace measured link testing.
