What You Can Measure with the OTDR

The OTDR displays the relative power of the returned

signal against distance. With this information important

characteristics of a link are determined:

What is Measured • the location (distance) of events on the link, the end of

the link or a break,

• the attenuation coefficient of the fiber in the link,

• the loss of an individual event (for example a splice), or

the total end-to-end loss of the link,

• the magnitude of the reflection (or reflectance) of an

event, such as a connector.

• the cumulative loss to an event can be measured

automatically.

A fully automatic function is available for these

measurements. The OTDR sets itself up to achieve the

best results.

What else an OTDR can do In addition to these features the OTDR is able to compare

measurement results:

• You can load up to two traces and display them on the

OTDR’s screen.

Scan Trace • Scan Trace is a full automatic analysis of the trace that

locates:

– Reflective events resulting from connections and

mechanical splices.

– Non-reflective events (typically fusion splices).

– Fiber End: the end of the fiber.

The Mini-OTDR detects the fiber end by scanning the

trace for the first Event with an insertion loss
