The Optical Wavelength Labs ZOOM 2 VFL (ZO-2V) is a highly accurate hand-held optical power meter, capable of measuring optical power and optical loss in a wide range of test environments, including LAN, MAN, WAN, Telco, CATV, Manufacturing, and Laboratory. A 2.5mm universal and 1.25mm universal connector port are included to connect to a wide variety of popular fiber optic connectors, including SC, ST, FC, LC, MU, and other SFF.

The ZOOM 2 VFL is enclosed in high-impact plastic, and a protective rubber boot provides additional shock protection. Its easy-to-read 4-digit LCD display shows optical power in dBm and dB, selected wavelength, and battery power. The ZOOM 2 VFL has an intuitive 2-button interface for controlling power ON/OFF and wavelength selection.

The ZOOM 2 VFL is N.I.S.T. Traceable and is calibrated at four commonly used industry standard wavelengths (850, 1300, 1310, and 1550), which makes it an ideal choice for both multimode and singlemode testing. Additionally, the ZOOM 2 VFL is calibrated at 1490nm, making it an excellent option for measurement of FTTx PON networks.

The ZOOM 2 VFL can store reference values for all of its calibrated wavelengths, and displays optical power as an absolute value in dBm or relative to a user set "zero" reference in dB. It has an intuitive two-button interface, with one button controlling power and wavelength selection, while the other is used to toggle between dBm, dB, and uW, as well as setting the optical reference, or "zero".

The ZOOM 2 VFL has been configured with a precision-coupled visual fault locator that is optimized for fiber optics. Its high-intensity red laser allows for fiber identification up to 1.5 kilometers away.

This VFL port can also be used to check for faults within a few feet of its launch point. When the bright red light encounters a fault, the light is deflected into the jacket, producing a red glow at the point of the fault.
