system cost, power consumption and footprint for short reach applications in the short- to mid- term perspective. ... Our recent demonstrations of 200 Gbps short-reach transmissions with 4-level pulse amplitude modulation (PAM) and discrete multitone signals are also presented as examples to show the system requirements ... short-reach IM/DD systems. ...doi:10.5281/zenodo.3625894 fatcat:gbcdsjfrffanhoogu5mwk5qeei
(IM/DD) optical system. ... The 224-Gbit/s line-rate OTPI-PAM-4 signal is successfully transmitted over a 500-m standard single-mode fiber (SSMF) in the C band, using the transmitter with a bandwidth of 25 GHz and the receiver with ... However, utilizing a large-bandwidth DACs and modulators for a high symbol rate signal may be difficult and undesirable for short-reach applications considering the cost and the power consumption  ...doi:10.1364/oe.397130 pmid:32680161 fatcat:e7x56qemhvbihlg6yefkhd7vkq
This paper provides a tutorial and a survey of VLC in terms of the design, development, and evaluation techniques as well as current challenges and their envisioned solutions. ... In addition to their high energy efficiency, LEDs are desirable for their low heat generation, long lifespan, and their capability to switch on and off at an extremely high rate. ... Acknowledgments We would like to acknowledge the Botswana International University of Science and Technology (BIUST) for research funding. ...doi:10.1155/2020/8881305 fatcat:wypzpfvejjdsjlqy4b6jitjiwe
In addition, a random blockage model must be investigated as LiFi signals can be blocked by opaque objects. ... These features are also the main features of WiFi, and WiFi is predicted to carry the majority of global mobile data traffic in the future. ... The reason for explaining the enhanced versions of PAM-SCFDE is because of the lack of further studies on PAM-SCFDE, which is in contrast to the number of studies of the IM/DD-based OFDM systems. ...doi:10.7488/era/1487 fatcat:ndq2ap4rmjfx5avwmx26ro2njy
I enjoyed our international dinner, birthday party, Friday movie night and all travels in EU, USA and China... I am also grateful for other former ECO people, Dr. Bas Huiszoon and Dr. ... Solomon Abraha for sharing the office room and making ... Therefore, the IM-DD scheme results in a cost-effective system without raising special requirements for the POF transceiver design. ...doi:10.6100/ir752630 fatcat:qvhe3ofhpvf5pekm7kynba5lou
