SONET Jitter Generation
The following jitter generation requirement applies to
STS-192 interfaces as defined in GR-253-CORE.
According to GR-253-CORE, jitter generation shall not
exceed 0.10 UI
measured using a bandpass measurement filter with a
high-pass cutoff frequency of 4 MHz and a low-pass
cutoff frequency of at least B3 = 80 MHz.
The S19252 meets the Telecordia Jitter Generation
Specification by having a worst-case jitter generation of
50 mUI
10 Gigabit Ethernet Jitter Tolerance
The following 10 Gigabit Ethernet jitter tolerance
requirement applies to 10GBASE-ER as defined in
IEEE 802.3ae. This total jitter is composed of three
components: deterministic jitter; random jitter; and an
additional sinusoidal jitter.
The three fundamental components of Jitter Tolerance
testing are:

The input jitter used to test receiver jitter tolerance is
specified by the receiver input jitter mask defined in by
