Note:

Transmitteddata: continuously transmitted “0”. In normal data transfer operation “0” and “1” will be transmitted

with the same probability. Therefore, for that case, about a factor of two of safety margin is included. However,

for worst case thermal stress testing such data pattern are often used and for this case the 400 mW/sr value

has to be taken.
