Attention to optical fiber communication networks has been paid in a recent paper showing their potential. Optical fiber communication networks can provide terabit aggregate capacities to buildings and offices in modern cities whereas practical wireless systems are orders of magnitude below this capacity. The authors reported on an indoor optical bidirectional wireless link with an aggregate capacity over 100 Gb/s. The link operated over ~3 m range at 224 Gb/s (6 x 37.4 Gb/s) and 112 Gb/s (3 x 37.4 Gb/s) with a wide field of view (FOV) of 60° and 36°, respectively. The authors said that this was the first demo of a wireless link of this type with a field of view that offers practical room-scale coverage.
