Laser bias current–minimum.
Laser bias current–maximum.
Optical power transmitted–minimum.
Optical power transmitted–maximum.
Optical power received–minimum.
Optical power received–maximum.
Setting the optical power received
establishes the received power level as
100 percent. If the receiver power
decreases, then the OPR percentage
decreases to reflect the loss in receiver
power. For example, if the receiver power
decreases by 3 dBm, the OPR decreases
50 percent.
