Notes:
1. Installation temperature is the range over which the cable can be bent and pulled without damage. Below -20°C the cable becomes brittle and
should not be subjected to mechanical stress.
2. Short term: 30mins.
3. Fail criteria for tensile force test: elongation higher than 5% of original length.
4. Bend angle is 90°. Bend radius is the radius of the mandrel around which the cable is bent.
5. Fail criteria for bend radius test: increase in attenuation higher than 0.5dB.
6. Long term: 24hours.
7. Bend angle is ±90°. Bend radius is the radius of the mandrel around which the cable is bent.
8. Fail criteria for flexing test: increase in attenuation higher than 0.5dB.
9. Fiber length longer than 2 meters.
10. Without connectors
11. Propagation delay constant is the reciprocal of the group velocity for propagation delay of optical power. Group velocity is v=c/n, where c is the
velocity of light in free space (3x108 m/s) and n is the effective core index of refraction.
12. Typical data measured at 25°C.
