Transport Networks

Softeco can target projects in the field of both optical and radio link transport networks with the most advanced technology solutions, capitalizing on its expertise in the management of the fundamental problems related  to the optical transmission (chromatic dispersion, noise, fiber and insertion attenuation).

Key element of this expertise is the Selesoft  laboratory, that allows a deep knowledge of the supported technologies, verifying  the functionality and the operations in the specific simulated conditions of the Customer environment .

In particular for the area of  P-OTS network (Packet Optical Transport System) and mobile backhauling networks (either IP or Ethernet based protocol), Proteco has highly specialized resources, that have decades of experience in solutions engineering.

To seize the opportunities of the domestic market, Proteco has signed a system integration agreement with Coriant, the leading provider of optical networking.

Under this agreement, Proteco operates as channel partner for  Coriant 7100 next-generation packet optical transport equipment and provide marketing services, systems integration and maintenance support in Italy.

The Coriant 7100 Packet Optical transport devices combine ROADM-based DWDM, SDH, OTN and Ethernet switching capabilities in a single platform. These features optimize the functionality of packet transport that are obtained by reducing the number of nodes per layer, the cost per bit and allow to simplify the operations of network supervision providing lower latency and high reliability.

Among the main projects that have taken advantage of this collaboration, we can mention the study for the introduction of a photonic layer in metropolitan area networks for a national Telcom operator. This study includes the photonics network architectural definition, the analysis of possible transmission problems, the impact on services currently offered by the operator and the evaluation of the savings in terms not only of CAPEX but especially of OPEX, thanks to the provisioning and operational tools that this solution allows to obtain, compared to the solutions based on traditional data devices.

A typical metropolitan network requires a different transport from each service edge node to the destination. Each connection must be appropriately sized based on the maximum utilization and an edge router is required to distribute traffic to the correct destination.

Metropolitan networks based only on routers and switches do not cost-effectively scale to support the constant evolving demand for bandwidth. These networks may require multiple overlapping rings, the deployment of new fiber and new hardware in each central. This process can be very inefficient, with high costs in terms of  design and deployment time.

Moving to a unified optical transport network, which supports multiple services on a single fiber pair, allows operators to share infrastructure costs among all their customers. From this point of view, a transport platform based on packet optical (P-OTS) is the network architecture that is increasingly considered successful by many operators around the world.
