The first practical terabit-scale hierarchical optical cross-connect system is realized by employing silica-based planar lightwave circuit devices. The system is scalable to 320 line cross connects + 160 client cross connects, and fully implemented e

The signal transmission characteristics of the first practical hierarchical optical cross-connect with a terabit-scale throughput are clarified experimentally employing 10-Gb/s wavelength-division-multiplexed signals. The observed power penalty was l

We propose a novel reconfigurable AWG-STAR (physical star topology network with arrayed-waveguide grating router) that employs two kinds of cyclic-frequency arrayed-waveguide gratings whose repetition channel numbers are coprime. We demonstrate that

The first practical hierarchical optical cross-connect system is developed and its feasibility confirmed using field-installed fibers. Fully-implemented equipment requires a 16-U chassis to manage 4.8-Tbit/s signals from 8 WDM lines and 160 client po

A single-carrier 10-Gbit/s system was installed into commercial networks and wavelength-division multiplexing technology was employed in laboratory tests to accelerate the transmission capacity to speeds of up to 1 Tera-bit/s. This successful transmi
