The rise of large-scale Data Centers to power the Internet infrastructure is driving new architectural directions for optical networking. This paper highlights these architectural options and discusses technology building blocks for scaling inter-Datacenter connectivity. OCIS codes: 060.4250 Networks; 060.1660 Coherent communications; 060.4256 Networks,(More)
We demonstrated a delay-line interferometer (DLI)-based, optical-signal-to-noise ratio (OSNR) monitoring scheme of 100  Gbit/s polarization multiplexed quadrature-phase-shift-keying (PM-QPSK) four-channel WDM at 50-GHz International Telecommunication Union (ITU) grid with <0.5  dB error for signals with up to 26 dB of actual OSNR. We also demonstrated data(More)
Submarine cables play a fundamental role in global telecommunications. In recent years, the internet traffic is experiencing a remarkable growth due to the large number of resource hungry applications which often require large traffic between data centers. In parallel with this traffic growth, optical transmission technologies have experienced a remarkable(More)
