We discuss the emerging rate-adaptable optical transmission technology and how this new
technology may be employed to further reduce the transport network cost to meet ever …

Today's society has been shaped in all its aspects by the progress in telecommunication
technology. Ever since the first developments that led to today's Internet and, later on, to the …

Network traffic demands are forecast to increase for the foreseeable future, with the
challenge being to meet the demand while maintaining or lowering network costs. Simply …

We evaluate the impact of variable-code-rate transceivers on cost, capacity and survivability
of wavelength-routed optical networks. The transmission rate and reach trade-off is …

Continued cost-and power-efficient capacity scaling in optical networks is imperative to keep
pace with ever-increasing traffic demands. In this paper, we investigate multi-wavelength …

We experimentally demonstrate real-time error-free transmission for longer than 65 h using
a 400G rate-adaptive flexible-grid transponder in a metro regional Telecom Italia …

As 100-Gb/s digital coherent systems enter commercial deployment, an effort is underway to
uncover the technologies that will enable the next-generation optical fiber communication …

Elastic optical networks with 25–100G format-versatile WDM transmission systems
Page 1 Abstract—We propose a network model based on format- versatile transceiver for …

The sustained growth of data traffic volume calls for an introduction of an efficient and
scalable transport platform for links of 100 Gb/s and beyond in the future optical network. In …

We propose a rate-adaptive optical transmission scheme using variable-rate forward error
correction (FEC) codes and variable-size constellations at a fixed symbol rate, quantifying …
