摘要

随着5G微基站建设密度急剧增加，因采用传统电缆供电方式，5G网络的建设成本和部署难度将大幅提升.光纤信能共传技术作为一种新型供电方式，利用光纤作为传输介质，实现1 064 nm能量光和1 550 nm信号光的共同传输，同时满足高速信号的5G前传和5G微基站的集中化能量管理.本文提出一种基于空分复用技术的光纤信能共传方案，基于10 km弱耦合七芯光纤实验实现了10 W能量光和1.5 Gbit/s速率5G新空口（New Radio，NR）信号光的共同传输，远端通过光电转换效率为35%的光伏电池获得了0.42 W的电功率，可驱动一个远端天线单元（Remote Antenna Unit，RAU），7 h连续监测接收能量光功率的波动范围小于0.4%.与此同时，接收到的5G NR信号误差向量幅度值（Error Vector Magnitude，EVM）仅为0.38%，创纪录地实现了6.3 W·（Gbit/s）·km电功率-容量-距离积.

Abstract

With the rapidly increase of the construction density of 5G micro base stations

the traditional cable power supply mode will greatly increase the construction cost and layout difficulty of 5G network. The co-transmission technique of signal and power over optical fiber as a new power supply mode

uses optical fiber as the transmission medium and co-transmits 1 064 nm energy light and 1 550 nm signal light

which can not only meet the high-speed 5G signal fronthaul

but also meet the centralized energy management of 5G micro base station. In this paper

a co-transmission scheme of signal and power over optical fiber based on space division multiplexing technology is proposed. 10 W energy light and 1.5 Gbit/s 5G new radio (NR) signal light are co-transmitted in the 10 km weakly-coupled seven-core fiber experiment. The 0.42 W electric power can be obtained by a photovoltaic converter with an optical-to-electrical conversion efficiency of 35%

which can drive a remote antenna unit (RAU). The fluctuation range of received optical power of energy light for 7 hours continuous monitoring is less than 0.4%. Meanwhile

the error vector amplitude value (EVM) of the received 5G NR signal is only 0.38%

achieving a record 6.3 W·（Gbit/s）·km electric power-capacity-distance product.
