OC-48/STM-16 Eye Mask
34 Set the oscilloscope to Eye Measure mode and setup to
measure the Average Power (in dBm) and Extinction Ratio.
Ensure Vertical Calibration and Extinction Ratio Calibration have been
NO TE
performed for the oscilloscope channel and vertical sensitivity range to
ensure measurement accuracy. Refer to oscilloscope information/Help if
necessary
35 Check the average optical power is between:
36 Check the extinction ratio is greater than 8.2 dB and record
the measured value.
37 If the instrument has dual wavelength option (1310 and
1550 nm ports) for 51 - 2.5 Gb/s, repeat
step 37
for the 1550 nm output and use 1550 nm settings as
appropriate for oscilloscope channel inputs.
