Abstract
Ever since the impressive properties of the EDFA were first reported, it has been recognized that the possibility exists that optical transmission might move beyond point-to-point or point-to-few-point transport to something much more exciting. In parallel, there has been much debate on the possibilities of "photonic switching," carrying the clear implication that photonics was soon to challenge electronics. Today we witness two lines of development for optical transport exploiting TDM and WDM, each having its limitations. The talk will compare these two approaches and discuss where each appears to fit within the evolving broadband network scenario.
