d) Cabling intended for use with high speed systems using laser sources may be tested with appropriate
laser sources to ensure that tests verify performance with that type of source.
17.4 OTDR Testing
a) The optical time domain reflectometer (OTDR) uses optical radar-like techniques to create a picture
of a fiber in an installed fiber optic cable. The picture, called a signature or trace, contains data on the
length of the fiber, loss in fiber segments, connectors, splices and loss caused by stress during
installation.
b) OTDRs are used to verify the quality of the installation or for troubleshooting. However, OTDR
testing shall not be used to determine cable loss.
c) OTDR testing should only performed by trained personnel, using certified equipment designed for
the purpose. The technicians performing the tests should be trained not only in operation of the OTDR
equipment, but also in the interpretation of OTDR traces.
d) See Appendix A for more information on OTDR testing.
