Notes:
1. Measured power is defined to be the measured power of the light emitted from receive fiber connector at OLIU.
2. The minimum measured received power allows for optical path penalty and unallocated margin. Connector loss
is not allotted for; it should already be accounted for in the optical power measurement.
3. The margin for falling within the max rx power is 1.0 dB.
