In this paper, we consider the problem of topology design for both unprotected and one-link protected all-optical networks. We investigate the problem of selecting switching sites to minimize total cost of the network. The cost of an optical network is expressed as a sum of three main factors: the site cost, the link cost, and the switch cost.For unprotected networks with linear cost model, we present a mixed integer linear programming (MILP) formulation of the problem. We also present an efficient heuristic to approximate the solution. The experimental results show good performance of the linear cost model heuristic. In 16% of the experiments with 10 nodes network topologies, the linear cost model heuristic had no error. Moreover, for 54% and 86% of the experiments with 10 nodes network topologies, the linear cost model heuristic's solution is within 2% and 5% of its optimal value respectively.Finally, we extend our approach to one-link protected networks, and present an efficient survivable heuristic, and representative experimental results.

“…They are critical to reroute the data traffic and increase the reliability of communication systems. In order to pass from the electronic-optical hybrid to all-optical network, optical switches are developed for increasing the speed of the network and reducing their cost [1]. In this way, many fiber optical switches have then been developed in literature.…”

In this paper, a 1 × 4 fiber optical switch based on an electromagnetic digital actuator having four discrete positions is presented. The mobile part of the actuator consists of a permanent magnet which can switch along two orthogonal directions and between four discrete positions. A mirror, fixed on the top side of the mobile part, reflects the collimated optical signal from an input fiber to one of four reception fibers depending on the mobile magnet position. The design of the digital actuator and the architecture of the switch are firstly described. An experimental prototype of the switch is then presented and experimental results are shown to demonstrate the feasibility of the proposed switch.
