USER'S MANUAL. PROLITE-50

4.2.1.3 Inspection Event

PROLITE-50 sends off a light pulse into the optic fiber to be inspected, and then
receive returning light signals, and starts calculating the "event" distance. The farther
the distance is, the longer time need for scattered light to be received by the instrument.
Event distance can be calculated according to the time of receiving events signals.
Through inspection of scattered signals, properties of optic fiber, connectors, tie-
ins can be identified.

4.3 Measurement Application of PROLITE-50

PROLITE-50 displays power relating to distance of returning signals. This
information can be used to identify the main properties of an optic fiber chain.

4.3.1 Measurement Contents of PROLITE-50

•
Event location (distance),end or rupture of optic fiber chain
•
Attenuation coefficient of fiber
•
Loss of a single event (for example, one optic tie-in), or total loss from upper
end to end
•
Range of a single event like reflection of connectors (or grade of reflection)
•
Auto measurement of cumulative loss of a single event

4.3.2 Trace Analysis of PROLITE-50

The trace analysis of PROLITE-50 is fully automatic. The trace locates:
•
Reflection events of connections and mechanic tie-ins
•
Non-reflection events (usually at welding tie-ins)
•
End of optic fiber (Through scanning the first loss event that is larger than end
threshold, end of optic fiber can be identified)
•
Events list: event type, loss, reflection and distance
