We experimentally demonstrate remotely powered, controlled, and monitored optical switching. The control signal of the switch is modulated on an optical wave and sent from a transmitter. At the switch location, the control signal is converted from an optical to an electrical signal to drive the switch. In addition, to provide electrical power at the switch location, optical power is sent from a distance and converted to electrical power using a series of photodiodes. We experimentally demonstrate (a) 1 Gb/s on-off keying data channel transmission and switching with a 1 MHz optically delivered control signal, and (b) 40 Gb/s quadrature phase-shift keying data channel transmission and remotely monitoring switch state and bias drift. The switching function is demonstrated without using any local electrical power supply. Moreover, the monitoring tones are transmitted to the remote switch and fed back to the transmitter to realize a switch state and detect the bias drift.

基于激光传输信号的远程供电、控制和监控光开关的实验演示

我们通过实验演示了远程供电、控制和监控的光开关。开关的控制信号在光波上调制并从发射器发送。在开关位置，控制信号从光信号转换为电信号以驱动开关。此外，为了在开关位置提供电力，从远处发送光功率并使用一系列光电二极管将其转换为电功率。我们通过实验证明了 (a) 1 Gb/s 开关键控数据通道传输和切换与 1 MHz 光传输控制信号，以及 (b) 40 Gb/s 正交相移键控数据通道传输和远程监控开关状态和偏置漂移。在不使用任何本地电源的情况下演示了开关功能。而且，
