C.1.2  Mean Launched Power

The mean launched power is the average power of a pseudo-random data sequence coupled into the fiber by the transmitter, which is measured at reference point S. The mean launched power indices of the optical interface types provided by the OptiX OSN 9500 are in line with relevant requirements, as shown in Table C-7.

Table C-7 Mean launched power

C.1.3  Extinction Ratio

Extinction ratio is the ratio of the average optical power level for a logical "1" to that for a logical "0" under the worst reflection and full modulation condition. The extinction ratio indices of the optical interface types provided by the OptiX OSN 9500 are in line with relevant requirements, as shown in Table C-8.

C.1.4  Receiver Sensitivity (STM-16/4/1: BER=1 ´ 10^-10; STM-64: BER=1 ´ 10^-12)

Receiver sensitivity is defined as the minimum acceptable value of average received power at point R to achieve a specified BER. The receiver sensitivity indices of the optical interface types provided by the OptiX OSN 9500 are in line with relevant requirements, as shown in Table C-9.
