10-Gb/s Transmission on Single-Wavelength Multichannel SCM-Based FDDI-Grade MMF Links at Lengths Over 300 m: A Statistical Investigation

Autor: Richard V. Penty, Ian H. White, J. D. Ingham, A. M. E-A. Diab

Publikováno v: Journal of Lightwave Technology. 25:2976-2983

We propose and comprehensively investigate a subcarrier-multiplexing (SCM) system based on 62.5-mum-core-diameter multimode fiber (MMF) using a single wavelength to achieve 10-Gb/s transmission over link lengths beyond 300 m, using 1.3-mum-wavelength

Measurement of the ‘single-photon’ velocity and classical group velocity in standard optical fibre

Autor: John Carroll, R M Thompson, J. D. Ingham, Ian H. White

Publikováno v: Measurement Science and Technology. 18:1538-1546

When engineering secure optical communication networks, it may be important to know if the photon velocity may be altered in a dispersive fibre by selecting photonic states with different ranges of Schr?dinger frequencies, (N + 1/2)f where f is the m
