ModCon Mode Controller - OEM
A compact board-mountable mode controller intended for integration inside OEM test instruments, delivering an Encircled Flux compliant launch.
Technical overview
The ModCon is a passive mode controller: a length of specially prepared multimode fiber in a sealed housing that redistributes the modal power of whatever source is connected to it. Because the output modal distribution is set by the device rather than by the source, an LED, VCSEL or FP laser test set all launch the same mode distribution into the fiber under test. Every unit is tested on Arden's MPX Modal Explorer to confirm the output meets the standard irrespective of the input distribution. The OEM version is housed in a small aluminium alloy enclosure with M2.5 or 3 mm mounting holes and short 900 um loose-tube buffered pigtails, so it can be built into a test set rather than used as an external patchcord. Dual-fiber variants carry both 50/125 um and 62.5/125 um fiber in one housing. Modal launch is specified in terms of Encircled Flux.
