With the current trend toward higher capacity in regenerated optical transmission systems (e.g., Ref. 1), increased emphasis has been placed on the jitter characteristics of such links. A number of jitter measurement experiments have been reported which feature either cascaded electrical2 or looped optical regenerators.3,4 Both techniques have disadvantages as practical system simulation tools. Regenerator cascades are expensive to implement, while regenerator jitter transfer functions cannot be conveniently modified while loop experiments are in progress.
