The emerging shape of optical networks: a European perspective

The first steps to introduce optical networks have already been taken, with amplified WDM systems available commercially and trials under way. By exploiting the inherent characteristics of photonics we should expect progressive increase of network capacity and functional capability yet with costs remaining the same or even falling. But what are the features that will make them friendly and attractive to the operator and user? Manageability, the versatility to support bandwidth hungry services and the ability to grow organically will all influence the emerging shape of optical networks. A European perspective will be taken.
