Home / Formula for Calculating Optical Cable Splice Loss
It's calculated by: Splice Loss (dB) = Number of Splices × Splice Loss Allowance (dB) By adding up these three factors, you can get the total link loss: Total Link Loss = Cable Attenuation + Connector Loss + Splice LossSplice loss is the loss of optical power at a splice. Extrinsic Optical Fiber Losses contains splicing loss, connector loss, and bending 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.
