  • Abstract
    A fast on-line OSNR measurement technique which uses the downhill simplex algorithm as a minimum finder is proposed and tested in CW signals for different OSNR levels with excellent agreement. The method is shown to be stable after 8 h of uninterrupted operation and is not affected by environmental temperature change during the test.
