In bandwidth abundant optical networks it is important to develop design strategies that are not only cost effective but also able to account for the inherent characteristics of the optical transmission medium responsible for the signal quality degradation. With this objective in mind, the paper proposes a design algorithm able to determine an appropriate placement of regenerators in Grouped Routing...
We evaluate the performances of scalable large-scale OXC architectures; all utilize a two-stage routing mechanism that dynamically groups wavelength paths and conditionally selects output fibers. The architectures are shown to reduce necessary hardware scale substantially.
We introduce and demonstrate an ultra-compact 55 waveband cross-connect module that can process 80 channels (50-GHz spacing) per fiber; it combines 50–100-GHz interleavers and two 5 5 waveband cross-connect (WBXC) modules with 100-GHz channel spacing that are staggered by 50 GHz. The interleavers have a nearly rectangular spectral shape so that this scheme minimizes the spectrum...
We evaluate hardware requirements for a newly proposed low-loss large-scale OXC architecture that utilizes two-stage routing. It is verified that the architecture attains significant hardware scale reduction and decreased loss.
We develop an ultra-compact 8x8 waveband cross-connect prototype which consists of eight optical couplers and eight 1×8 waveband selective switch modules that are monolithically integrated onto PLC chips. Experiments verify its transmission performance.
We propose a novel large-scale OXC architecture that utilizes WSSs for dynamic wavelength grouping and 1xn switches for fiber selection. Our network design algorithm shows that the architecture attains significant hardware scale reduction. A prototype demonstrates good transmission performance and confirms the architecture's technical feasibility.
We present a hardware scale analysis of our proposed large-scale OXC architecture that is based on dynamic wavelength grouping and fiber selection. Numerical experiments show that it significantly reduces the number of necessary WSSs.
We develop an ultra-compact 5×5 waveband cross-connect module that can process 80 channels (50 GHz spacing)/fiber employing interleavers and two component WBXCs with 100 GHz channel spacing. Its practical applicability is verified through transmission experiments.
