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 Tensile Force is for less than 30 minutes.

3. Short Term Bend Radius is for less than 1 hour nonoperating.

4. 90° bend on 25 mm radius mandrel. Bend radius is the radius of the mandrel around which the cable is bent.

5. Typical data are at 25°C.

6. 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

7. Note that
