6.1.6 Receiver Sensitivitya) Measurement description: the optical Signal is generated by the STM-1 transmitter; an opticalattenuator is used to adjust the optical attenuation. The optical input power is set to the minimum allowed value and the correspondent BER is measured.Afterwards the attenuation is increased until the BER reaches the value specified (1x10-10).

b) Expected Results:In according to table 2 of ITU-T G.957 the minimum sensitivity has to be:

a) Measurement description: With no applied jitter, increase the attenuation until a BER of 1E-10 is observed at the SDH analyzer. Decrease1dB the attenuation.Set the input jitter frequency according to ITU-T recc. and adjust the jitter amplitude until the BER returns to1E-10.Change the jitter frequency and repeat the test.

Note: sometimes with SFP optical transceiver the alarm LOS is active with B.E.R. 1E-10; in this case the testwill be performed at 1dB from the LOS deactivation level (see next section of this document)

b) Expected Results:The input jitter should be as described in ITU-T G.825 table 4 and figure 1.

6.2.10 Alarms

b) Measurement description:The optical power at the receiver input is decreased with an optical attenuator till the alarms are detected viaSW by a craft terminal .The attenuation value for alarm activation and deactivation has been noted. Moreover the optical signal at the receiver input is erred and alarmed at through the instrument andchecked for error and alarms occur.

b) Expected Results: The Error Count value, for alarm activation and deactivation has been noted.

6.2.11 Long Term BER Testb) Measurement description: Purpose of this test is to control that no error occur for a time of 12 hours

for every temperature with the optical receiver at Sensitivity level + 3dB or at LOS level activation +3dB (ifthe loss of signal is detected for BER < 1E-10).

b) Expected Results: No error for a test duration of at least 12 hours.
