Abstract

The fastest transmission systems demonstrated to date are at a bit rate of 8 Gbit/s [1,2]. Laser modulation experiments at 10 Gbit/s NRZ and 8 Gbit/s RZ were recently reported [3,4] as well as simulations using the highest frequency components of a 16 Gbit/s NRZ code [5,6]. Recent improvements in the cut-off frequency of FETs and increases in laser modulation bandwidth now allow the investigation of optical systems at higher speeds by electronically multiplexing pseudorandom 2 Gbit/s signals of length 2¹⁵-1 into a 16 Gbit/s NRZ bit stream.
