Testing Fibers in Template Mode (optional)

OTDR 59

Restrictions of Template Mode

When you process traces using an OTDR, you acquire the traces as you go

along. When you process traces on a computer, you use traces stored on

disk; therefore, applying the span length is optional.

Item To be valid...

Pulse width  Must be:

Pulse width

 This would also be valid:

Fiber types Compare singlemode traces with singlemode traces.

Number of

events

Traces must have at least two events (span start and span end) and a

fiber section.

Acquisition

mode

Reference trace must not be acquired in Real mode (see Setting Distance

Range, Pulse Width, and Acquisition Time on page 43).

Wavelengths Reference wavelengths and wavelengths of subsequent (or reloaded)

traces must be identical.
