In this Letter, we propose and demonstrate a novel wireless communications link using an illuminating optical fiber as transmitter (Tx) in camera communications. We indoor proof-of-concept system plastic coupled with light-emitting diode commercial the Tx receiver, respectively. For first time, to best of our knowledge, experimentally flicker-free transmission within off-axis rotation angle ran...

We evaluate the benefit of reconfiguration after single-link failures in supporting recovery from additional failures. We also develop an intuitive classification of two-link failures to help understand the impact of failures. c 2003 Optical Society of America OCIS codes: (060.4250) Fiber optics and optical communications/networks; (060.4510) Fiber optics and optical communications/optical comm...

We report a cascaded optical link of 1100 km for ultra-stable frequency distribution over an Internet fiber network. The link is composed of four spans for which the propagation noise is actively compensated. The robustness and the performance of the link are ensured by five fully automated optoelectronic stations, two of them at the link ends, and three deployed on the field and connecting the...

We consider transmitter–receiver (Tx–Rx) parameter optimization for a vertical underwater wireless optical communication link under misalignment conditions. The Tx is assumed to use light-emitting diode, whereas the Rx uses silicon photomultiplier that allows high sensitivity. two typical application scenarios and investigate of parameters optimize performance in terms outage probability. deriv...

Power link budgets are prepared for wireless optical communication systems to illustrate the optical losses that happens during transmission. This paper has presented optical wireless links which offer ultra multi gigabit per second data rates and low system complexity. For ground space and or terrestrial communication systems, these links suffer from atmospheric loss mainly due to fog, and sci...
