MPX Modal Explorer

The MPX Modal Explorer provides real-time measurement of Encircled Flux. Simply connect your source and patchcord to the MPX, and it will measure their Modal Launch Conditions in real-time.

Encircled Flux is now widely accepted as the preferred way to specify modal filling by IEEE, TIA and IEC. Measurement of Encircled Flux is defined in FOTP-203 - the"Modal Explorer" is the most standards-compliant measurement system available today and has been chosen by major standards labs in the USA and Europe as the basis for their critical measurements.


Features and benefits
  • End face mode for precise focus giving better repeatability from operator to operator

  • Power monitor - ideal for optimising light throughput and modal conditions together for production of pig-tailed light sources.

  • Real-time measurement - means for the first time you can adjust modal conditions easily as well as increase productivity

  • Internal LED for use as Encircled Flux reference source - complies with IEEE 802-3 for coherent sources

  • USB2.0 direct connection gives portability - ship the Modal Explorer to distant locations with the optional carrying case plus a laptop computer.


  • Source and patchcord characterization for IEC 11801 LAN testing

  • VCSEL characterisation for Gigabit Ethernet IEEE 802.3

  • Mode-scrambler and mode-filter characterization

  • LRM Encircled Flux measurements

  • Set up fiber coupled sources
