Installation temperature is the range over which the cable can be bent and pulled without damage. Below -20C 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 25C. 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 8 velocity of light in free space (3xl0 m/s) and n is the effective core index of refraction. 7. Note that a rises at the rate of about 0.0067 dB/C, where the thermal rise refers to the LED temperature changes above 25C. Please refer to R Figure 1 which shows the typical plastic optical fiber attenuation versus wavelength at 25C. 2
