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.
OTDRs are
mainly used in the optical fiber installation and maintenance servicing
of access networks (communications links between telephone exchanges and
telephone poles) and user networks (communications links between user
sites and telephone poles).
Our broad lineup of OTDRs offer cost
performance, field durability, and applicable dynamic range. With thirty
years of innovation in reflectometry design we deliver technology
solutions where you need them most.
