Frequently Asked Questions

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 LED Light Source has a compact handheld design, provides stable 85/85% launch conditions for multimode fiber measurements, and comes with a rechargeable Li-Ion battery with 48hr life.

The 85/85% modal launch condition is used specifically in the aerospace industry, and it’s widely used by Airbus for certification of its optical fiber harnesses.

The technical specifications of the ALS LED Light Source include source type (LED), centre wavelength (1300nm or 850nm), spectral width (155nm or 50nm), dimensions (200 x 120 x 35mm), weight (0.5kg), optical power output (-20dBm), optical power stability (± 0.05 dB over 1 hour), optical launch condition (85/85% Limited Phase Space), and connector interface (FC).

The full insertion loss test kit includes an ALS - LED light source, a battery charger, a power meter, and all the power meter leads/patchcords/couplers required.
