Mode controller from Arden Photonics controls LED or VCSEL light
The ModCon mode controller can be used to modify an LED or VCSEL light source to provide repeatable EF-compliant launch conditions. Measurements of loss and bandwidth in multimode fibers depend on the modal condition of the light source used. Plugging this into a light source provides stable and consistent output that meets IEC 62180-4-1.
