SONET Jitter Requirements
SONET equipment jitter requirements are specified for the following three types of jitter. The definitions of each
of these types of jitter are given below. SONET equipment jitter requirements are specified for the following
three types of jitter.
4.6.1
Jitter Tolerance:
Jitter tolerance is defined as the peak-to-peak amplitude of sinusoidal jitter applied on the input OC-N
equipment interface that causes an equivalent 1dB optical power penalty. OC-1/STS-1, OC-3/STS-3, OC-12
and OC-48 category II SONET interfaces should tolerate the input jitter applied according to the mask of
Figure 24 and Figure 25 show jitter tolerance performance of XRT91L31.
