For source independent mode control fit the ModCon to your light source and

• Improve measurement accuracy
• Ensure stable launch conditions for multimode fiber measurements
• Meet EF requirements of IEC 61280-4-1 OR 85/85 launch conditions required in some aerospace applications.

The ModCon Mode Controller is designed to ensure that whatever source you use to test the loss and bandwidth of your multimode optical fiber network, LED, Laser, OTDR or white light, you launch the same distribution of modes into the fiber. As a result you can eliminate the variations due to the widely different modal characteristics of the sources commonly used in fiber optic measurements and networks.
