04 Aug 1998TL;DR: In this article, a guide structure is used to guide optical fiber fed to various stations on the guide structure which correspond to input and output ports of a fiber shuffle interconnect, allowing the fibers to be bundled to a common input and/or output port.
Abstract: An apparatus and method is provided for optical cross connections. A guide structure is used to guide optical fiber fed to various stations on the guide structure which correspond to input and output ports of a fiber shuffle interconnect. Once the fiber has been positioned about the guide structure, the fiber is arranged such that the input and output ports of the interconnect align allowing the fibers to be bundled to a common input and/or output port. In this manner, once the fiber is arranged about the guide structure, fiber management becomes an easy task because the number of fiber bundles is significantly smaller than the total number of individual fibers.

TL;DR: This paper proposes and evaluates a filterless network architecture for a trunk and branch undersea network topology and shows that the filterless architecture can bring significant cost savings for both the terminals and line equipment while offering the same agility as the conventional network architecture.
Abstract: Active photonic switching components, such as reconfigurable optical add/drop multiplexers (ROADMs), cannot be deployed at the branching units (BUs) in submarine networks, which limits the flexibility of the undersea networks. In this regard, the filterless optical network architecture based on passive broadcast-and-select nodes and coherent transceivers at the edge terminals can be considered as a promising solution. In this paper we propose and evaluate a filterless network architecture for a trunk and branch undersea network topology. The performance is compared with a conventional solution in terms of cost and wavelength consumption. And it is shown that the filterless architecture can bring significant cost savings for both the terminals and line equipment while offering the same agility as the conventional network architecture.

28 Jul 2015TL;DR: In this article, the authors proposed a protocol optimization method in a switch that operates a plurality of CC sessions with a peer switch, where, for CC intervals, N sessions of the plurality CC sessions are set to a short interval and M sessions of a plurality CC session are set in a long interval, wherein N and M are integers.
Abstract: A Continuity Check (CC) protocol optimization method in a switch includes operating a plurality of CC sessions with a peer switch, wherein, for CC intervals, N sessions of the plurality CC sessions are set to a short interval and M sessions of the plurality of CC sessions are set to a long interval, wherein N and M are integers; switching a first session of the N sessions with a second session of the M sessions based on one of a fault and user provisioning; and exchanging the CC intervals between the first session and the second session subsequent to the switching.

TL;DR: The purpose of this article is to review the key emerging innovations in laser and photonics systems as well as their design and integration, focusing on challenges and opportunities for solutions of societal challenges.
Abstract: The purpose of this article is to review the key emerging innovations in laser and photonics systems as well as their design and integration, focusing on challenges and opportunities for solutions of societal challenges. Developments, their significance, and frontier challenges are explained in advanced manufacturing, biomedicine and healthcare, and communication. Systems, networks, and integration issues and challenges are then discussed, and an integration framework for networking laser- and photonic-based services and products is proposed. The article concludes with implications and an agenda for education, research and development, and policy needs, with a focus on human, society, science, and technology integration. © 2013 Wiley Periodicals, Inc.

02 May 2003TL;DR: In this paper, a distribution stage is disclosed comprising a plurality of inputs coupled to first-and second-stage switching devices, and a distribution configuration is configured to enable the switching network to be expanded without degrading the switching performance of the network.
Abstract: A distribution stage is disclosed comprising a plurality of inputs coupled to a plurality of first stage switching devices, a plurality of outputs coupled to a plurality of second stage switching devices, and a distribution configuration. The distribution configuration is configured to receive a plurality of bandwidth units (BU's) from each first stage switching device, and to distribute at least one BU from each first stage switching device to each second stage switching device, such that each second stage switching device is assured of receiving at least one BU from each first stage switching device. In effect, the distribution stage ensures that each first stage switching device has a logical link to each second stage switching device. In one embodiment, the distribution stage is configured in accordance with a distribution configuration that is static. Because the distribution configuration of the distribution stage is static, it does not add complexity to the overall switching determination of a switching network. Thus, the distribution stage enables the switching network to be expanded without degrading the switching performance of the network.
