1000 sensors, one line, using optical fiber

Adding sensors to systems for purposes such as predictive maintenance is an application of growing interest in the Internet of Things (IoT) era. But if wireless sensors are not appropriate, developers can quickly run into a massive wiring problem as they try to connect large arrays of individual strain gauges, temperature sensors, and other sensor types. Happily, there is an emerging technology that employs optical fibers.
