The Optical Wavelength Labs Silicon ZOOM 2 VFL (ZO-2SV) is a highly accurate option for measuring the optical power of multimode fibers at 850nm. The Silicon ZOOM 2 VFL is NIST traceable, and is calibrated 650, 850, and 980nm. Reference values used for optical loss readings are stored for each of these wavelengths.

Its user-friendly interface includes two push-buttons: one for power and wavelength selection, and one for setting references and toggling between dBm (optical power) and dB (optical loss).

The Silicon ZOOM 2 VFL includes a 2.5mm universal connector, which is compatible with many popular fiber connectors, such as ST, SC, and FC. A 1.25mm universal connector port can be purchased separately, allowing for connection to LC, MU, and other SFF connectors.

The Silicon ZOOM 2 VFL is ideal for fiber optic professionals who need to quickly measure the loss in their fiber optic links and do not require data point storage.

The Silicon ZOOM 2 VFL includes a precision-coupled visual fault locator optimized for fiber optics. An optical ball lens placed near the laser output focuses the light for optimum input into fiber optic cables, and special current-limiting electronics prevents laser burnout (a common problem with pen-style laser pointers), increasing the life of the VFL.
