Abstract
This paper examines the relative importance of wavelength conversion and time‐slot interchange in improving the performance of multiwavelength time‐division multiplexed networks. It is shown that, in networks with a small number of wavelengths, each carrying a large number of time‐division multiplexed channels, significant performance improvements are achieved by the introduction of time‐slot interchange alone, without wavelength conversion. However, some performance improvements are also achieved by the introduction of wavelength conversion alone.
