“…Potential use of optical amplifiers to increase the number of nodes that a fiber-optic network can support has been investigated by many researchers [8][9][10][11]. In [8], semiconductor optical amplifiers are used to increase the number of nodes supported by a fiber-optic bus topology by at least an order of magnitude.…”

In this paper, we propose a novel method for expanding the size of FDM/WDM passive star networks using high-power erbium-doped fiber amplifiers (EDF). In contrast to other proposed methods where each receiver would require its own EDF amplifier, the proposed method requires few amplifiers located at the central hub of the star network. The size of the network can be increased by m times using m narrowband EDF amplifiers with a sufficient level of output saturation power. Moreover, the optical amplifier bandwidth requirements are less stringent compared to those of other known methods. An additional advantage of our method is that existing networks can be expanded or interconnected requiring minor modifications.

“…In this paper we consider the application of amplifier cascades to multichannel operation over shorter haul terrestrial links [10]- [12]. In the United Kingdom network for example, transmission distances would be at most a few hundred kilometers, which can be achieved with a relatively modest number of amplifiers.…”

As a result of recent advances in erbium-doped fiber amplifiers it is clear that transmission systems employing optical amplifier repeaters will outperform their electronically regenerated counterparts in many applications. For example, substantial cost savings can be envisaged when optical amplifiers are combined with wavelength division multiplexing (WDM) techniques in order to introduce additional capacity and transparency into future optical transmission networks.In this paper, we consider the requirements and practicalities of amplifier cascades for multichannel coherent transmission. We describe a four-amplifier cascade which maintains an overall noise figure of less than 13 dB across a 20 nm optical bandwidth for total input powers up to -10 dBm. A potential capacity of one-hundred WDM channels is demonstrated in a 300 km 622 Mb/s DPSK coherent transmission experiment.
