Encircled Flux (EF) is the final piece in the puzzle of reducing measurement uncertainty in multimode optical fiber cable loss measurements. It is potentially the biggest contribution to variations in loss measurements.
Arden Photonics has released new software for its MPX Modal Explorer, a system for checking the launch conditions into multimode fibre using real-time measurement of encircled flux.
The standards-compliant system is applicable to users of both MPX-1 (850nm) and MPX-2 (1300nm) units with a USB 2.0 interface between computer and MPX optical unit.
