We propose a simple and robust frequency domain method for measuring modal delay and bandwidth of bi-modal optical bers. An analytical transfer function model is formulated showing excellent agreement with experimental results for relatively short bers. If a comprehensive guide on selecting the appropriate MMF for a particular system deployment is required, please consult AE Note. Mode-dependent loss (MDL) is known to have a detrimental impact on the capacity of multi-mode fiber systems.
