Answer Posted / abdus sattar mollah
by instrument name OTDR: Optical Time Domain Reflexometer.
It injects laser beam into optical fiber through patch cord
and provides a graph between attenuation (dB) and Distance
(m).{performance decresess for shorter distance)
The graph's nature shows the cable performances.The graphs
has rising peaks followed by decaying lines.Spikes in the
decaying lines indicates severe loss.So,if we have smooth
decaying graph then it reflects good optical fiber
path.Whereas Spikes in curve indicates energy loss which
can be corrected by maintenence of Media Converter(OFC)
converter.Also the splice joings of fiber should not exceed
a maximum 0f 0.1 dB (calculated by Arc splicer Instruments).
