Encircled Flux Meter MPX-1A
A benchtop instrument that measures the modal launch condition (Encircled Flux) of a multimode light source and patchcord at 850 nm. It is used to verify that a test source meets the launch requirements of the multimode loss-measurement standards.
Technical overview
The MPX-1A images the near-field output of a connected source onto a CMOS array and derives the Encircled Flux profile in real time. Auto-focus and auto-exposure remove operator dependence, and an integrated 850 nm over-filled reference source allows the launch to be checked against the standard limits. Measurements are reported against TIA-526-14-A, IEC 61280-4-1, TIA/EIA-455-203, IEC 61280-1-4 and IEEE 802.3. The unit connects to a Windows PC over USB 3.0 and offers an optional API for production integration.
