4-Gb/s transmission experiment over 117 km of optical fiber using a Ti:LiNbO₃external modulator

Abstract

We report a single-channel optical fiber data link with the largest bit-rate <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">x</tex> repeater spacing product achieved to date- ∼ 0.5 Tb . km/s. The multi-gigabit per second system is the first to incorporate a Ti:LiNbO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> external modulator as the data encoder.
