The challenge of transition to fibre in the loop

The benefits of deploying existing products (switch remote unit and line multiplexer) on an SDH transport network are outlined. IT is demonstrated that it is possible to achieve a pre fiber-in-the-loop (FITL) deployment capable of providing all the services required while laying the backbone and preparing the transition to FITL system. Line multiplexers and small remote units can achieve a service rich platform. It is demonstrated that careful planning can reduce the amount of fiber rework and make network deployment more future proof.
