Abstract :
We demonstrate a receiver, which improves the back-to-back (b-t-b) performance of optical duobinary signals at 10 Gb/s. The required optical signal-to-noise ratio for a bit-error rate of 1×10-3 was found to be as low as 10.8 dB in b-t-b operation. We tested the receiver with two commercially available 10-Gb/s duobinary transmitter samples. Excellent chromatic dispersion tolerance was maintained with the novel receiver design.
