Optical networks require faster
compensators
Tomorrow at OFC 2004 in Los Angeles, Siemens ICN will report on potential network failures in WDW systems caused by fast polarisation changes.

Fluorescence filter patent awarded
Semrock, a leading provider of high-performance optical filters, announced today that it has been awarded U.S.Patent No. 6,809,859 for its popular BrightLine series of fluorescence filters.
Polarisation mode dispersion (PMD) contributes a major obstacle for the deployment of already installed fibre for high speed long haul optical transmission using per channel bitrates of 10Gbit/s or above.
Yet PMD is not a static effect but fluctuates due to temperature changes and mechanical vibrations that might be caused by trains going by or technicians working on the associated hardware.
Due to the increasing unregenerated span count of future transparent photonic networks PMD will have a bigger impact on error free transmission than today.
Unlike former observation, PMD or polarisation changes on a microsecond timescale were observed that influence transmission considerably.
Therefore the measurement and correction processes of PMD compensators need to be increased in speed.
The presentation will be held on 27th February at 1115 local time in room 515B of the Los Angeles Convention Centre.
