Design adn developing of intelligent hardware to digital and optical performance monitoring for up to 10G DWDM transport applications with lambda tracking

The TITAN project is a two-year R&D project (2007-2008) based on optical network architecture and network technologies focused on: DWDM optical networking, metro optical networks, optical channel performance monitoring and tributary channel digital aggregation. Finally, the evaluation of the developments were made in a field trial implemented in an experimental optical network.

  • Incorporate DWDM systems, to speed 10Gbit/s based on SFP and XFP transceivers , subsystems that enable control and monitoring of the QoS of the transmitted digital signal through the extraction and evaluation of DM in frames SDH.
  • Develop subsystems what can incorporate the DW or FEC field for any protocol : SDH , GbE , FC , SDI , …, until a transmission speed of 10 Gbit / s , to detect and correct bit errors and evaluate the BER.
  • Develop low cost subsystems to assess the quality of a link at 4Gbits / s ( maximum speed of the FC protocol) , by incorporating electrical switching modules , SPA , error detection and evaluating the BER.
  • Develop submodules with digital performance monitoring analysis for any protocol.
  • Realization of a prototype, using GFP and VCAT, for adding FC or GbE asynchronous channels in a synchronous container STM -64 ( SDH to 10 Gbit / s ).
  • Incorporate the control subsystems of the optical signal quality ( “Optical performace monitoring, OPM ” ) which can feed the layer of control and management of the optical transport network.
  • Develop subsystems for tracking and identification of the channel at any point DWDM optical network, by associating a specific pilot tone joined the channel.
  • Develop embedded subsystems within the optical transmission can evaluate the chromatic dispersion of the optical link , such information can be implemented for each DWDM channel and agile automatic dispersion compensation introduced by the optical fibers.
  • Develop subsystems based on tunable optical amplification and chromatic dispersion compensation in order to implement all-optical links which can cover large distances fiber and pass transparently through several optical nodes.
