Abstract
This paper describes a family of systems developed to make better use of the vast usable bandwidth provided by optic fibers. All systems described are frequency division multiplexed (FDM). Special attention is paid to the possibility of reducing channel spacing by signal processing using optic filters and of improving receiver sensitivity by using Erbium-doped fiber amplifiers (EDFA). A suitable filter-amplifier configuration is proposed for each possible application, like LANs, WANs, and Long Haul Systems.
