An application area which was developed later, but has acquired a large market volume, is that of computer mice. A laser mouse with a VCSEL as light source can have a high tracking precision combined with a low electricity consumption, as is important for battery-powered devices.Due to the short resonator round-trip time, VCSELs can be modulated with frequencies well in the gigahertz range. This makes them useful as transmitters for optical fiber communications and for free-space optical communications. For short-range communications, 850-nm VCSELs are used in combination with multimode fibers. A data rate of e.g. 10 Gbit/. VCSELs can also be used in miniature optical clocks, where the laser beam probes an atomic transition in cesium vapor. Such clocks could become part of compact GPS devices.Due to their high output powers, VCSEL arrays can often compete with diode bars (partially even with diode stacks), e.g. for pumping solid-state lasers.

Distributed Vibration Optical Cable
Distributed Acoustic Sensing (DAS) systems detect strain changes and vibrations along optical fibers. This highly sensitive technology is used for monitoring critical infrastructure such as power cables, pipelines, or railroad tracks. Distributed fiber optic vibration/acoustic sensing technology utilizes the Rayleigh back-scattered light generated by periodically injecting laser pulses into fiber. What is Distributed Fiber Optic Vibration Sensing (DVS)? Distributed Fiber Optic Vibration Sensing (DVS) is an advanced optical sensing technology that uses single-mode optical fiber (SMF, G652 recommended) as both the sensing medium and signal transmission carrier. Distributed Fiber Optic Sensing (DFOS) is a technology that enables continuous, real-time. Lightera AcoustiSens Optical Fibers are intended for use as components in optical and hybrid cables Lightera AcoustiSens Products are intended for use as components in optical and hybrid cables designed for vibration or acoustic sensing applications such as: AcoustiSens Fibers AcoustiSens Cables.
