C.1.2 Mean Launched Power
The mean launched power at reference point S is the average power of a pseudo-random data sequence coupled into the fiberby the transmitter. Table C-4 shows the mean launched power of each optical interface provided by the OptiX 155/622H.

C.1.3 Extinction Ratio (EX)The extinction ratio refers to the ratio between the average optical power of the transmitted signal (reflected optical signal) and that of the empty signal (non-reflected optical signal) in the caseof the worst reflection condition and full modulation. The extinction ratio indices for each optical interface provided by the OptiX 155/622H are shown in Table C-5.
