Abstract

Fifth-generation (5G) technology has enabled faster communication speeds, lower latency, a broader range of coverage, and greater capacity. This research aims to introduce a bidirectional high-speed passive optical network (HS-PON) for 5G applications and services including mobile computing, cloud computing, and fiber wireless convergence. Using 16-ary quadrature amplitude modulation orthogonal frequency division multiplexing techniques, the system transmits uplinks and downlinks with a pair of four wavelengths each. Light fidelity (LiFi) services are provided with blue light-emitting-diode-based technology. With a threshold bit error rate (BER) of 10−3, the results demonstrate reliable transportation over a 100 km fiber at −17 dBm received power and in a maximum LiFi range of 20 m. Furthermore, the system offers symmetric 4 × 50 Gbps transmission rates under the impact of fiber–LiFi channel impairments with maximum irradiance and incidence half-angles of 500. Additionally, at threshold BER, the system provides a detection surface range from 1.5 to 4 cm2. Compared to existing networks, the system also provides a high gain and low noise figure. A number of features make this system an attractive option. These include its high speed, high reach, high split ratio, low cost, easy upgradeability, pay-as-you-grow properties, high reliability, and ability to accommodate a large number of users.

利用前端 LiFiSystem 研究 5G 网络中基于 OFDM 的 HS-PON

第五代（5G）技术实现了更快的通信速度、更低的延迟、更广的覆盖范围和更大的容量。本研究旨在推出一种双向高速无源光网络（HS-PON），用于移动计算、云计算和光纤无线融合等 5G 应用和服务。该系统采用 16 端正交调幅正交频分复用技术，以一对各四个波长的上行链路和下行链路进行传输。光保真（LiFi）服务采用基于蓝光发射二极管的技术。在 10-3 的阈值误码率（BER）下，研究结果表明，在接收功率为 -17 dBm 和最大 LiFi 范围为 20 米的情况下，100 千米光纤上的传输是可靠的。此外，在最大辐照度和入射半角为 500 的情况下，该系统可在光纤-LiFi 信道损伤的影响下提供对称的 4 × 50 Gbps 传输速率。此外，在阈值误码率下，系统的探测面范围为 1.5 至 4 平方厘米。与现有网络相比，该系统还具有增益高、噪声系数低的特点。该系统的一系列特点使其成为一个极具吸引力的选择。这些特点包括：高速度、高到达率、高分光比、低成本、易升级、边成长边付费、高可靠性以及能够容纳大量用户。

期刊介绍： Photonics (ISSN 2304-6732) aims at a fast turn around time for peer-reviewing manuscripts and producing accepted articles. The online-only and open access nature of the journal will allow for a speedy and wide circulation of your research as well as review articles. We aim at establishing Photonics as a leading venue for publishing high impact fundamental research but also applications of optics and photonics. The journal particularly welcomes both theoretical (simulation) and experimental research. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
