Test I. Dynamic Range
1 Connect the equipment as shown in Figure 74 (single-
mode module), or Figure 75 (multimode model).
Terminate the far end.
The fiber is terminated by wrapping it five times
around the shaft of a screwdriver (or some similar
object with a diameter of around 5 mm).
If you are using the Agilent Recirculating Delay line,
connect part 1 to the Mini-OTDR.
The specific measurement techniques of the Agilent
E6000C require a fiber length which is adapted in
attenuation and backscatter to the requirements of the
selected pulsewidth.
The fiber specified for this test is of general type and valid
for all pulsewidths. A shorter fiber should not be used, as
the uncertainty of the measurements would increase by
some dB.
