We demonstrate that quadrature phase-shift keying modulation with phase-sensitively pre-amplified coherent receivers provides the highest capacity for space- and deep-space optical communication li

The receiver sensitivity is a very important metric in optical communication links operating at low received signal powers.

We consider the problem of minimizing the power consumption of Internet backbone networks by means of power aware design and auto configuration of Points of Presence (PoPs).

This study assesses the feasibility of defining different service classes based on protection schemes in core optical networks.

This study assesses the feasible energy savings when defining different service classes based on protection schemes in core optical networks.

We demonstrate power efficient 320 Gb/s transmission over 17,545 km, and 560 Gb/s over 6,050 km, using 98 GBd PDM-QPSK/64QAM and CMOS DAC technology. We apply digital and optical pre-emphasis.

Power equalisation with simultaneous signal regeneration is demonstrated with a semiconductor optical amplifier all-optical wavelength converter based on the delay interferometer configuration.

Power equalization with simultaneous signal regeneration is demonstrated with a semiconductor optical amplifier (SOA) all-optical wavelength converter based on the delay interferometer (DI) configu

The Hierarchical Energy Analysis Tool lets designers quickly estimate power consumption of various data-path architectures, enabling a power consumption comparison at a high level before the layout

The principal objectives in the power plant design for the Transatlantic cable system were as follows: 1.
