Ethernet is becoming increasingly popular in metro and carrier-grade networks because of its cost-effectiveness, simplicity and scalability. Nevertheless, Ethernet was originally designed as a LAN technology, therefore, it lacks some features, such as fast fault-protection and sophisticated management, which are very important in the new carrier-grade(More)
This paper describes Project GIGA-high-speed Experimental Network, a multiinstitutional, multidisciplinary, national project funded by the Brazilian government. The main goal of Project GIGA is to promote research, development and experimentation of technology at all layers, aiming at generating knowledge, products and services that will make it possible(More)
Plug and play optical (PPO) nodes may be used to facilitate the deployment of optical networks. PPO nodes must be able to learn about the signal propagation properties of the surrounding optical fibers and make their wavelength routing decisions based on the collected data. This paper discusses what are the open challenges that must be overcome to provide(More)
For asynchronous sampled systems such as Polarization Division Multiplexed Quadrature Phase Shift Keying, (PDM-QPSK), phase and frequency of the sampling clock is typically not synchronized to the data symbols. Therefore, timing adjustment, so called clock recovery and interpolation, must be performed in digital domain prior to signal demodulation in order(More)
