A 100-Mbċs^-1fiber-optic communication channel

How to compute two complex even Fourier transforms with one transform step

“…E. SIEGMAN Procedures exist for calculating the discrete Fourier transforms of two real N-point functions, simultaneously, or the transform of a single real 2N-point function, or the transforms of N-point even and odd complex functions simultaneously, using only one pass through a complex Npoint discrete Fourier transform (DFT) routine [ 11, [ 21 . A procedure has also been described for computing the transforms of two real even N-point functions using only a single NIZ-point DFT step [ 31 .…”

Optical channel speeds for future transport networks

“…The bit error rate (BER) curves of the received optical signals were measured. In the same year, White and Chin reported an investigation of a 100-Mb/s fiber communication system, in which the light from a LED was modulated and coupled into a 60-um multimode fiber [3]. Meanwhile Ozeki and Ito reported a 200-Mb/s experimental optical communication system [4] and Miller, Marcatili, and Li reported a 300-Mb/s optical communication result as well [5].…”
