One new unused Fluke network controller NFK1-EFLC-SC 62.5Um multimode encircled flux launch controller, 62.5 µm, SC/LC. I have several, and can email each individual units Serial Number if needed for reference.
The controller is a Multimode modal conditioner/controller (ModCon) for use with loss testing instruments. This Modcon apparatus is designed to be attached externally to FNET LED sources currently in the field. Attaching this apparatus to a customer's DTX-MFM2, for example will bring the source launch conditions into encircled flux (EF) compliance per the IEC 61280-4-1 standard thus achieve more accurate test results and better agreement between different test sets
Two Required for DTX-MFM2s for Encircled Flux compliant optical loss length testing Ensure stable launch conditions for multimode fiber measurements Meet Encircled Flux requirements of IEC 61280-4-1. Free Shipping in the US only.
