Optical Time Domain Reflectometers
An optical time domain reflectometer (OTDR) is a precision instrument used to locate events or faults along a fiber link, typically within an optical communications network. The OTDR launches a series of high speed optical pulses into the fiber to be measured. Various events on the fiber generates a Rayleigh back scatter that returns to the OTDR and the strength of the return pulses are measured and integrated as a function of time, and plotted as a function of fiber length. The horizontal axis is the distance and the vertical axis is the loss.

Circuit Breaker Time Interval Meter
Measuring contact timings is useful for finding the contact bounces and non-simultaneity of contacts. This helps in finding the possible electrical or mechanical defects in the circuit breaker contacts. Timing analysis also make it possible to detect incorrect mechanical adjustments and wear phenomena of the circuit breaker by measuring the differences between the fastest and slowest phases.
