1.2 Attenuation Coefficient
Test Procedure:
1. Connect the test sample either to the instrument or to one end of end dead-zone fiber. Connect the other end
of the dead-zone fiber (if used) to the instrument.
2. The accurate locations of point defects are to be recorded; the effective group delay index of the test sample
is required. Use IEC 60793-1-40 (Method C) to determine it.
3. Enter OTDR parameters such as source wavelength, pulse duration, length range, and signal averaging into
the instrument, along with the test sample effective group index. The values of some of these parameters may
be present in the instrument.
4. Adjust the instrument to display a backscatter signal from the test sample. It may be advantageous to begin
with coarse vertical and horizontal scaling to maximize the length displayed. An example is given in Figure
1.
Figure 2 Schematic of OTDR Trace
5. When possible, repeat the test for a single launched into the test sample in the opposite direction. A more
accurate loss estimate (and the elimination of apparent gain) is made by averaging readings taken directionally
at the same wavelength .This eliminates the effect of any backscatter different for the fiber sections on both
side of the defect.
6. If required by the Detail Specification, repeat the test at another wavelength.

it for the correct distance to the aperture assembly.
4. Set the aperture assembly to a small aperture, and adjust the far field to an aperture lateral alignment for
maximum detected power.

3.2 Crush Test

Test procedure:
The set-up for the Crush Test is shown in Figure 6.
The sample was of a length sufficient to carry out the specified test.
The apparatus allowed a sample of cable to be crushed between a flat steel base plate and a movable steel plate
which applies the crushing force uniformly over a 100 mm length of the sample.
The edges of the movable plate were rounded with a radius of about 5 mm. The edges were not included in the
100 mm flat part of the plate.
The cable sample was mounted between the plates so that lateral movement is prevented, and the force was
applied gradually without any abrupt change.
The test was performed three times, the force being applied on the specimen at three different places not less
than 500 mm apart, without rotating the cable.
Unless otherwise specified, the conditions for testing shall be in accordance with standard atmospheric
conditions.

3.3 Impact Test
Test procedure:
The sample length was sufficient to carry out the specified test. When only physical damage is to be evaluated,
the length may range from 1 m (for example for small diameter jumper cords or duplex cables) to 5 m (for larger
diameter cables). Longer lengths may be necessary to permit optical measurements.
The sample was terminated at each end in a connector, or in a manner such that the fibers, sheathings and any
strain members are clamped together in a representative manner. The clamps on the impact apparatus may be
adequate, or the sample may be long enough so that no restraint is needed.
