NOVEMBER 28, 2008 -- Telecom Engineering (search for Telecom Engineering) has announced a new DWDM Four Wave Mixing (FWM) software package called F-Intermod. F-Intermod is designed to allow engineers to easily and quickly determine all FWM wavelengths that can interfere with DWDM channels.

FWM occurs in fiber links when two or more DWDM wavelengths interact with each other, creating new wavelengths in the fiber. These new wavelengths can fall onto existing DWDM channel assignments and cause interference in the channels. F-Intermod calculates these new wavelengths and identifies which DWDM wavelengths are mixing together to create them. DWDM channel assignments can then be better planned to reduce interference due to FWM. F-Intermod can determine FWM wavelengths created by up to 1,000 DWDM wavelengths.

F-Intermod is available as a free seven-day trial download from the company's website.
