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.
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.
Measurements of loss and bandwidth in multimode fibers are known to be highly dependent on the modal condition of the light source used for the measurement. For example, OTDR and LS/PM loss measurements can differ significantly simply because an OTDR uses a laser source and not an LED.
Now there is a way to dramatically improve agreement AND ensure you meet international standards at the same time – the ModCon. The ModCon is a passive device which ensures that the correct launch conditions are achieved independent of the light source used. This results in more accurate measurements, better agreement between different test sets, and compliance with international standards. Every ModCon is rigorously tested using Arden’s MPX Modal Explorer to ensure that its output meets the standard regardless of the modal distribution of the input.
