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 αR 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.
