Optical Transport Network

The Altran OTN software framework is the first of its kind and a game-changer for OEMs and service providers in the optical transport market.

As Optical Transport Network (OTN) continues to gain momentum as the technology of choice for long-distance, high-capacity, resilient transport networks, providers need to keep up while guaranteeing that service levels stay high availability and resilient. Altran’s OTN software framework is a highly cost-effective solution that allows Original Equipment Manufacturers (OEMs) to accelerate development of next generation OTN equipment.

Software Benefits:

Our framework supports the building of variety of products, including pure optical switches, packet optical transport equipment and multiplexers. Various price-feature combinations can be supported via the same software foundation, leveraging the end user’s investment across a portfolio of products.

In addition to the strong technical and cost benefits of the OTN software framework, Altran offers a variety of complementary software frameworks including software frameworks for packet networks in the access, edge, aggregation and core networking space, as well as solutions for Software Defined Networking (SDN) applications and Network Function Virtualization (NFV) orchestration.
