OLK51NMM Test Set LED OM120NI/OS420N
The OLK51NMM is a Test kit designed for multimode applications. The OLK51NMM combines the OM120NI optical power meter and OS420N LED sender and is ideally suited for testing fiber optic networks with multimode cables. The OM120NI power meter includes such features as an 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 a Set Reference feature which stores selected wavelengths absolute value to memory. The OS420N is a 850nm /1330nm LED light source, both LED's are potted in fixed ST housings and are individually adjustable.
