Figure 1–46: Optical impulse response for OC–12 SONET Reference Receiver
NOTE. In Figure 1–46 the left cursor has been moved to the zero dB level. The
right cursor remains at the OC–12 data rate of 622 MHz "4 MHz (the delta
frequency is 584 MHz because the right cursor is no longer referenced to DC).
The delta attenuation from the zero dB level to the 622 MHz Cursor is 5.6 dB.
6. Repeat steps 5d through 5f, starting on page 1–97, moving the second cursor
to twice the bit rate (1.5 times the bit rate for the FC1063 standard).
7. For an exhaustive test of the reference receiver, repeat steps 5d through 5f for
each frequency shown in Table 1–12 for the standard.
8. If verifying additional standards, repeat this procedure for each standard.
