|
| 6.Attenuation
lrregularity: |
|
At the curve of fiber's backward scatter,the
attenuation value measure on any 500m fiber |
|
subtract the mean attenuation value measured
every 500m over the whole length of the
fiber, |
| and
the worst value should not be more than
0.05dB. |
|
|
| 7.Attenuation
characteristics: |
|
The attenuation value between the 1525~1575nm
shall not exceed 0.05dB/km compared with
|
wavelength
of the 1550nm. |
|
| 8.Fiber
mechanical strength test: |
|
The fibers should be proof tested
over the whole length to an equivalent level
of stress of |
|
more than 0.69Gpa(the strain is about
1%) for 1 second. |
