Mapping algorithm for protecting a network using a Wavelength Division Multiplexing (WDM) infrastructure against component or link failures while respecting capacity constraints. ...
Schemes - Hardware duplication or Mapping algorithm - for protecting a network using a Wavelength Division Multiplexing (WDM) infrastructure against component or link failures. ...
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 ...
A device, which follows the CCITT recommendations, has been developed to measure attenuation, spot-size and cut-off wavelength of single-mode fibers in the 0.9 to 1.6 μm wavelength range. In developing this device, great care was given to reliability and e ...
A new optical local area network that combines dense Wavelength Division Multiplexing (WDM) techniques and coherent transmission benefits is presented. A new multichannel protocol is specified based on Ethernet, using WDM to carry multiple channels on a si ...
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 ...
