Arden Photonics’ "ModCon" gets multimode fibre launch conditions under control

15 May 2009

Arden Photonics Ltd announces the ModCon mode control patchcord. It eliminates the problem of incorrect "modal filling", a major cause of inaccuracy in loss measurements on optical fibre premises cabling (50/125µm and 62.5/125µm multimode fibre).

The ModCon is a passive device that ensures standard-compliant modal filling, whatever test equipment you use. Measurements of loss and bandwidth in multimode fibres are known to be highly dependent on the modal condition of the light source used for the measurement. Now there is a way to dramatically improve agreement AND ensure you meet international standards at the same time - the ModCon. The ModCon 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 the Mode Power Distribution (MPD) requirement specified in ISO/IEC 14763-3. Every ModCon is tested using a Modal Explorer to ensure that its output meets the standard regardless of the modal distribution of the input. Simply fit the ModCon between the test set and the Fibre Under Test. Technical Specification
