ModCon Mode Controller 12 channel

The ModCon Mode Controller 12 Channel by Arden Photonics is a high-performance passive device designed to provide consistent and repeatable mode conditioning for multimode fiber testing across multiple channels. Ideal for 12-way switching systems, ribbon fiber assemblies, and multi-fiber test environments, the ModCon ensures that optical measurements remain accurate, stable, and compliant with international testing standards regardless of the light source being used.

Multimode fiber measurements are highly sensitive to the modal distribution of the launched light. Different sources such as LEDs, VCSELs, and Fabry-Pérot lasers can excite fiber modes in different ways, often leading to significant variations in measured loss and bandwidth results. The ModCon eliminates this source dependency by conditioning the launched light to produce a controlled and repeatable modal distribution. As a result, test engineers, network installers, and manufacturers can achieve improved measurement consistency, better correlation between test instruments, and greater confidence in test results.

The 12 Channel ModCon is particularly well suited for applications requiring simultaneous testing of multiple fibers. Available in a compact 19-inch, 1U rack-mounted format, it can be configured with MPO-style connectors for high-density fiber connectivity or with individual FC or SC connectors to suit specific test setups. Every unit undergoes rigorous verification using Arden Photonics' advanced modal measurement technology to ensure reliable compliance with industry standards and dependable performance in demanding environments.
