Mathematical model for splice loss estimation in few-mode fibers based on mode field diameter
Abstract:
We present an extended mathematical model for estimating splice losses in few-mode fibers (FMFs). The proposed model accounts for mode field diameter (MFD) mismatch between spliced fibers and reveals a quantitative relationship between MFD and splice loss for each mode. Numerical simulations validate our mathematical analysis, demonstrating that the model can accurately estimate splice losses for each mode using MFDs. This capability makes it a valuable tool for telecom operators in designing FMF transmission distances and optimizing the number of splices.

What is a Mode?
There can be more than one mode in a data set if multiple values have the same highest frequency. For instance, suppose that the Statistics exam scores of 20 students are: 50; 53; 59; 59; 63; 63; 72; 72; 72; 72; 72; 76; 78; 81; 83; 84; 84; 84; 90; 93. Here, the mode is 72, as it occurs most frequently, five times.
A data set with two modes is called bimodal. For example,...
