Yokogawa Visible Light Source
The AQ1215E-VLS is a visible light source module designed for use with Yokogawa's AQ1215 series optical time domain reflectometers (OTDRs). This module emits visible red light, typically at 650 nm, and is used for visual fault location in optical fibers, allowing technicians to easily identify breaks, bends, or other faults by observing the visible light escaping from damaged points. The AQ1215E-VLS is an official accessory that enhances the troubleshooting capabilities of the AQ1215 OTDR, providing a practical solution for fiber identification and continuity testing in the field.
