General Description
This advanced diagnostic tool for optical fibres allows the Fibre Engineer to take a snapshot of
a fibre link. The OTDR sends short pulses of light down one end of a fibre at a specified
repetition rate. Light reflected back from fibre discontinuities and light continuously back
scattered from the fibre itself travels back to the OTDR, where the instrument records the
optical power and arrival time. The arrival time of the pulse from a given point in the fibre is
related to its distance from the OTDR. With this information, the OTDR graphically displays
returned power versus distance. OTDRs are well-equipped for troubleshooting problems
because they allow you to visually locate reflective events like connections and fibre breaks
and non-reflective events like splices and tight bends by studying the graphical trace. The
power difference between two points on the trace is an estimate of optical loss.
