[摘要] 基于对采用射频、可见光、780～950 nm红外光作为可见光通信上行链路的分析，提出了采用1 550 nm激光作为可见光通信上行链路的全新方案，在典型室内应用场景下，与下行的可见光链路共同构成一套波分双工全光通信链路，其上行链路可达1 Gb/s。1 550 nm激光上行链路同样具有速率高、无电磁干扰、与保密性好等与可见光通信相一致的特点，可以成为可见光通信上行链路候选方案之一。

[Abstract] This paper analyzes the features and feasibility of the uplink utilizing wireless radio frequency, visible light, and 780-950 nm infrared light for visible-light communication. In addition, a novel uplink scheme employing 1550 nm laser and avalanche photo diode is presented. This scheme maintains the advantages of high-speed, no electromagnetic interference, and enhanced security. The simulation results indicate that this uplink can achieve a data rate of 1 Gb/s.
