Abstract :
Optical wavelet domain reflectometry (OWDR) is proposed for the first time as a novel alternative to optical time domain reflectometry (OTDR) and optical frequency domain reflectometry (OFDR) to measure and characterize an optical fibre. We include a succinct review of system constraints and problems arising in OTDR and OFDR, describe the idea and design of OWDR, and show the considerable progress that we have made in dealing with the constraints and overcoming these problems with OWDR
