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
velocity of light in free space (3xl08 m/s) and n is the effective core index of refraction.
7. Note that aR rises at the rate of about 0.0067 dB/°C, where the thermal rise refers to the LED temperature changes above 25°C. Please refer to
Figure 1 which shows the typical plastic optical fiber attenuation versus wavelength at 25°C.
8. Not available for Commercial (Type="C") cable
