Abstract :
An optical equalizer consisting of a reflective cavity structure, which gives an all-pass amplitude response and a frequency-selective delay response, is described. Equalizer performance is evaluated for links using external modulation with chirp absent. It is also shown that, by using equalizers of the type described, the receiver data eye can remain open for distances more than twice those where the unequalized system becomes inoperable.<>
