  Model networks and their underlying topologies have been used as a reference
for techno-economic studies for several decades. Existing reference topologies
for optical networks may cover different network segments such as backbone,
metro core, metro aggregation, access and/or data center. While telco operators
work on the optimization of their own existing deployed optical networks, the
availability of different topologies is useful for researchers and technology
developers to test their solutions in a variety of scenarios and validate the
performance in terms of energy efficiency or cost reduction. This paper
presents an open-source tool, MoleNetwork, to generate graphs inspired by real
network topologies of telecommunication operators that can be used as
benchmarks for techno-economic studies.
