The feasibility of a survivable all-optical transport network over standard single-mode fibre between eight major European cities is investigated. The chosen topology is intended to ensure survivability after a link or a node failure. The maximum transmiss ...
The authors describe an optical fiber link that is used in conjunction with the CERN host interface family to connect high-performance VAXes to VMEbus or FASTBUS over distances up to 1000 m. The modular construction allows other permutations, including VAX ...
A single failure in a communication network can trigger many alarms. We propose an alarm filtering algorithm for the management of an optical network using Wavelength Division Multiplexing (WDM). The algorithm supports: (i) multiple failures and (ii) passi ...
Schemes - Hardware duplication or Mapping algorithm - for protecting a network using a Wavelength Division Multiplexing (WDM) infrastructure against component or link failures. ...
Recent papers have pointed out that data traffic exhibits self-similarity, but self-similarity is observed only on a finite timescale. In order to account for that, we introduce the concept of pseudo long-range dependencies. In this paper, we describe a Mo ...
Wavelength demultiplexing is a very promising application of photoinduced fiber gratings. In this paper efficient outcoupling of a very narrow wavelength band, in addition to the usual guided Bragg reflection, is presented. The selective outcoupling gratin ...
An optical network is described that is capable of recognizing at standard video rates the identity of faces for which it has been trained. The faces are presented under a wide variety of conditions to the system, and the classification performance is meas ...
A single failure in a communication network can trigger many alarms. We propose an alarm filtering algorithm for the management of an optical network using Wavelength Division Multiplexing (WDM). The algorithm supports: (i) multiple failures and (ii) passi ...
With WDM networks, the failure of a single link or component may cause the simultaneous failure of several optical channels, potentially making impossible the restoration by rerouting in higher layers directly using the optical network (SDH, ATM, IP). To a ...
Polarization dispersion is an effect which may cause data rate penalty in optical links. This is caused by the combined effect of fibre birefringence and polarization couplings due to environmental perturbations. Polarization dispersion is therefore a stoc ...
