The way in which optical fibre networks are deployed and managed is changing radically, in ways that both service providers and network managers need to take heed of.

The traditional transmission network model has historically been based on a 'dumb' physical tier (copper, or more recently optical fibre cable), with managed intelligent data, routing, network and application layers sitting above.

However, as we move from analogue voice to multi-functional data services, demands on networks have changed rapidly. In addition, the wide choice of service providers requires those that win business to be cost effective, reliable and quick to market.

In this climate, a 'dumb' physical layer is no longer acceptable, as its inflexibility limits the benefits of the more intelligent, higher layers. A more flexible and managed approach needs to be taken instead. In the context of fibre infrastructure, this is still a new concept, and it is only with modern, optical switching technologies that true, real-time management has become feasible.

The Guidelines put forward potential methodologies for achieving this, as well as discuss the options of 1st versus 3rd party management and examine the areas of infrastructure management that need to be addressed.
