TL;DR: It is demonstrated that optical path technologies such as WP and VWP enhance not only the transmission capacity, but also cross-connect node throughput cost-effectively by capitalizing on the wavelength routing scheme, resulting in significant transport network cost reduction.
Abstract: This paper explores the transport technologies that will enable a further leap forward in transport network evolution. It is demonstrated that optical path technologies such as WP (wavelength path) and VWP (virtual wavelength path) enhance not only the transmission capacity, but also cross-connect node throughput cost-effectively by capitalizing on the wavelength routing scheme. This results in significant transport network cost reduction. Optical path realization technologies focusing on optical path cross-connect systems are examined. Requirements for the optical path cross-connect system are elucidated and a new cross-connect system architecture is proposed. The architecture exploits PLC (planar lightwave circuit) and other commercially available technologies suitable for mass-production. It is proved that the architecture has various advantages such as highly modular-growth capability, low optical loss, and the maximum commonality for WP and VWP. The optical path technologies introduced in this paper will pave the way for a new transport network paradigm, a ubiquitous, bandwidth-abundant and affordable broadband ISDN.

TL;DR: In this paper, the authors identify crosstalk sources in limited-wavelength-interchanging cross connects (L-WIXC) and calculate the power penalty imposed by this.
Abstract: Identifies crosstalk sources in limited-wavelength-interchanging cross connects (L-WIXC) and calculates the power penalty imposed by this. Specifications for the components used in the L-WIXCs can then be determined for obtaining a specified level of system performance.

TL;DR: A reconfigurable non-blocking 4-port silicon thermo-optic optical router based on Mach-Zehnder optical switches that can manipulate 50 wavelength-division-multiplexing channels with the data-rate of 32 Gbps for each channel is demonstrated.
Abstract: We demonstrate a reconfigurable nonblocking 4-port silicon thermo-optic optical router based on Mach–Zehnder optical switches. For all optical links in its 9 routing states, the optical signal-to-noise ratios are larger than 15 dB in the wavelength range from 1525 to 1565 nm. Each optical link of the optical router can manipulate 50 wavelength-division-multiplexing channels with the data rate of 32 Gbps for each channel in the same wavelength range. Its average energy efficiency is about 16.3 fJ/bit, and its response time is about 19 μs.
