The ModCon Mode Controller

EF compliant to IEC 62180-4-1

Improves measurement repeatability in multi-mode fiber test

Optimized for 850nm

Works with all multi-mode fiber optic testers

Plug and play Encircled Flux compliance
The Arden Photonics ModCon Mode Controller is a compact and lightweight module that will modify
your LED or VCSEL light source to provide repeatable EF compliant launch conditions.
By simply plugging the ModCon into your light source you will be provided with a stable and consistent
EF compliant output that meets IEC 62180-4-1:2009.

How does it work?
Measurements of loss and bandwidth in multimode fibers are 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.
These widely different modal characteristics between sources used in measuring fiber optic systems
and networks result in a large and source dependent uncertainty in the accuracy of measurements.
When using a ModCon, you launch the same distribution of modes into the fiber regardless of the
source being used and consequently reduce the uncertainty in your measurements due to variation
between sources.
In summary the ModCon increases the accuracy of measurements, gives better agreement between
test data sets and is a simple and certifiable method of complying with international standards.

Standards compliance and certification
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. Additionally we can provide a Certificate of
Conformance or Test Sheet to aid in fulfilling any of your test equipment record keeping obligations.
