1300nm or 850nm LED
For 62.5/125 µm or 50/125 µm fiber
Rechargeable Li-Ion battery with 48hr life
The ALS handheld optical fiber source is used with an Optical Power Meter to measure the loss of multimode
optical fiber systems, in applications which require 85/85% Limited Phase Space modal launch conditions. The
ALS provides excellent stability and ease of use.
The 85/58% modal launch condition is used specifically in the aerospace industry, and it widely used by Airbus for
certification of its optical fiber harnesses.
