Relaxing the alignment in underwater wireless optical communication systems is highly favorable for practical use. Employing wavelength-division-multiplexing (WDM) adds to the requirement of alignment since multiple filters are used at the receiver side to separate the incoming wavelengths. We report the use of scintillating fibers in WDM systems as signal detectors that offer valuable advantages such as large-area detection, widefield-of-view and high data rates. We demonstrate the optimal selection of wavelengths based on the fibers’ characteristics, and realise an aggregated data rate of 400-Mb/s using on-off keying modulation format with zero-forcing equalization and maximum ratio combining in an outdoor diving pool in a maximum separation distance of 10-m.
