Optimum optical amplifier location in spectrum-sliced WDM passive optical networks for customer access

摘要

Spectrum slicing is an attractive scheme for implementing wavelength-division multiplexing (WDM) passive optical networks (PONs) in the customer access environment. Amplification of signals from the filtered broadband incoherent sources that are typically used in spectrum-sliced PONs is dominated by noise processes to those found in systems using narrow-band laser sources. In this paper we examine the tradeoffs that determine the optimum location of the amplifier that maximizes the power budget for a spectrum-sliced WDM PON that uses incoherent sources.
