Optical networking is likely to result in substantial cost savings in
future telecommunications networks. The scalability and design flexibi
lity of these networks are critical features which may influence the n
ature of future networking products. In this paper, we experimentally
investigate networking technologies for optically time division multip
lexed systems. We demonstrate significant advantages in terms of scala
bility, design flexibility and technology interoperability over the tr
aditional wavelength division multiplexing approach.
