10.7 Gb/s Transmission over >200km of Standard Singlemode Fiber Using Forward Error Correction and Duobinary Modulation
01 January 2003
We report, for the first time to our knowledge, 10.7 Gb/s transmission at low optical signal-to-noise ratio through >200 km of standard singlemode fiber without dispersion compensation. Using forward error correction and duobinary signaling, under 1 dB of dispersion-induced power penalty is reported after 200 km with only 20 dB received OSNR.
