The ZOOM II is one of the world's most economical and precise fibre optic power meters delivering professional performance and a complete feature set for optical loss testing in both multimode and singlemode networks.

The ZOOM II 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 II is calibrated at 1490nm, making it an excellent option for measurement of FTTx PON networks.

The ZOOM II 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".

Other standard features include a 4-digit, 0.01dB resolution display, battery status indicator, and a 2.5mm Universal detector port that is compatible with FC, ST, SC, DIN, and any other 2.5 mm ferrule connectors!  

The following accessories are included with each ZOOM II: rugged rubber boot, carrying strap, NIST certificate of calibration, and operations manual on CD.

The ZOOM II can also be upgraded to include data storage and a download port to turn it into a full-featured fiber optic link certification power meter.

ZOOM II series test kits are available as multimode, singlemode or quad wavelength. 850nm only multimode kits are also available as a budget solution.
