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.

IXI Technology’s highly-accurate card provides time down to 62.5ns resolution in UNIX format. Its time-sourced, disciplined, voltage-controlled crystal oscillator (VCXO) or optional CSAC not only allows it to provide sub-second resolution, but also to “flywheel” during the absence or loss of carrier. The module has a status LED that indicates when the internal time is synchronized with the input time code. The card provides a programmable offset on its internal time from the input time source. The generated IRIG-B or 1588 output can be configured to be synchronous to the chosen input time source or configured to use the best available time source.
