1 Introducing the Optical Time
Domain Reflectometer
The Optical Time Domain Reflectometer allows you to characterize a
fiber-optic span, usually optical fiber sections joined by splices and
connectors. The optical time domain reflectometer (OTDR) provides an
inside view of the fiber, and can calculate fiber length, attenuation, breaks,
total return loss, and splice, connector and total losses.
