4.6 SONET Jitter Requirements

SONET equipment jitter requirements are specified for the following types of jitter. The definitions of each of

these types of jitter are given below. SONET equipment jitter requirements are specified for the following two

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 23, with the corresponding parameters specified in the figure.
