Abstract: A fiber optics communication link (20) for a remote mobile (22) vehicle employs a single strand of optical fiber (26) to convey control data from a stationary control station (24) to the vehicle and to simultaneously convey environmental data generated by transducers carried by the vehicle back to the control station. At the control station, the received optical signals are converted to an electrical form and demodulated to recover the environmental data. Additionally, encoded and modulated optical signals corresponding to the control data are provided to the second combiner/splitter (56) for transmission via the fiber to the first combiner/splitter (36). At the vehicle the received optical signals are converted to electrical form, decoded and demodulated to recover the control data, and used to control the vehicle and transducers. Frequency multiplexing is used in different directions along the single fiber in order to eliminate noise due to reflections along the optical path.

Abstract translation: 用于远程移动（22）车辆的光纤通信链路（20）使用单股光纤（26）将控制数据从固定控制站（24）传送到车辆并且同时传送由换能器产生的环境数据 由车辆携带回控制站。 在控制站，接收到的光信号被转换成电形式并被解调以恢复环境数据。 此外，对应于控制数据的编码和调制的光信号被提供给第二组合器/分离器（56），以经由光纤传输到第一组合器/分离器（36）。 在车辆处，接收的光信号被转换成电形式，进行解码和解调，以恢复控制数据，并用于控制车辆和换能器。 沿着单根光纤在不同方向使用频率复用，以消除由于沿光路的反射引起的噪声。
