The accumulation of pattern-dependent jitter for a chain of fiber optic regenerators

The experimentally validated linear, shift-invariant jitter model of an individual fiber-optic regenerator is used to derive the jitter accumulation model for a chain of nonidentical fiber-optical regenerators. The jitter characteristics of 40 regenerators are measured individually and are used as parameters in the jitter accumulation model. The calculated accumulation is compared to an accumulation measurement made along a chain of these same 40 regenerators to estimate the portion of pattern-dependent jitter that accumulates systematically. >
