The OM120N-I is a general-purpose power meter suitable for a both premise and outside plant applications. This unit incorporates such features as a enlarged screen for optimal viewing, extended battery life (100+ hours), tone detection (270Hz, 330Hz, 1KHz & 2KHz), dBm\dB\Watts read out and an auto off feature (optional 10 or 30 min). The unit utilizes an InGaAs detector and its calibrated wavelengths include 850/1300/1310/1490/1550 &1625nm. All wavelengths have aSet Reference feature which stores selected wavelengths absolute value to memory.

 This unit is ideal for measurement of optical power and optical loss (attenuation) in a fiber optic network. When paired with an OS400N series source the OM120N-I series meters are ideal for single mode (OS430N laser source) or multimode (OS420N LED source) applications.
