CONNECT researchers are now digging into existing fiber-optic cables underground, as they explore uses beyond communications networks.
A new initiative could see existing fiber-optic internet cables double up as sensor networks for applications including environmental monitoring.

FIGURE 1. Comparison of laser frequency deviation: The unlocked laser (gray) exhibits significant environmental drift, while the analog lock (blue) suppresses most of this noise but is limited by hardware-induced drift and component tolerances. The digital implementation (green) leverages high-speed DSP to achieve a near-zero error signal and provide the superior stability required.
