Fibre length meter

OZ Optics Limited has developed a meter designed to measure
the lengths of optical fibres from a few millimetres to 500 metres. The system
can measure lengths of multimode, single-mode and polarization maintaining fibres.
The device works by measuring the time it takes an optical signal to travel
along and back through a fibre. Readings
are updated once per second to allow continuous monitoring of the fibre length,
which also allows the device to be used as an optical strain sensor. Readings
are communicated to a logging computer via a USB
interface.
