Versatile Handheld Optical Light Sources
MULTIWAVELENGTH CAPABILITY
Excellent stability & High measurement accuracy
Description
Versatile light sources include a dual-wavelength multi-mode (850/1300nm) or single-mode (1310/1550nm) light source (others specify on requests, Max wavelength is 5 in one main body) with w/ Auto-wavelength/Tone Generation/Recognition (Dedicated Digital Encrypted Protocol)*, Premium SC & FC Switchable Adapters and Alkaline Battery (3xAA, 1.5V) & AC Power Supply Adapter. When used with the power meter, together they provide accurate test solutions for fiber optic networks. Switchable adapters allow flexibility with reference cords.
*Note: Dedicated Digital Encrypted Protocol means it cannot comply with power meters of another brand because every company has its own protocol to achieve that.
