Single-mode fiber splice loss
Splice loss occurs whenever the mode fields of two joined fibers do not perfectly overlap. This tool uses the Marcuse Gaussian Approximation to calculate losses from intrinsic mismatch and extrinsic alignment errors. To be able to judge whether a fiber optic cable plant is good, one does a insertion loss test with a light source and power meter and compares that to an estimate of what is a reasonable loss for that cable plant. We then use observed data to estimate these model parameters; both Bayesian and maximum.
