Advanced Fiber Solutions, Inc. (AFS), AF-OLK51N-SM, AF-OLK5N NextGen Series Single Mode Fiber Optic Test KitThe AF-OLK5N NextGen series test kits are the latest addition to the AFS product family. This inexpensive optical test kit is the complete solution necessary for the installer to test and trouble shoot both multimode and single mode fiber optic systems. These test kits are designed to allow testing of all parameters of fiber optic networks, including output power levels from the fiber, coupled source power and attenuation loss in a cable.The AF-OLK51N-SM Test Kit combines the AF-OM120N-I optical power meter and the AF-OS430-NU laser light source and is ideally suited for testing long haul and outside plant fiber optic networks with single mode cables. The AF-OM120N-I power meter includes such features as a enlarged screen for optimal viewing, extended battery life (100+ hours), tone detection (270Hz, 330Hz, 1KHz & 2KHz), dBmdBWatts 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 AF-OS430N is a 1310nm /1550nm Laser light source, which comes equipped with interchangeable ST, FC and SC connector adapters).Kit ContentAF-OS430-NUAF-OS420AD-100 (2.5mm Universal Adapter)Product ManualBatteriesAlco wipesMeter Cal Cert.Kit Highlights and Key FeaturesCompact light weight carrying case850nm, 1300nm, 1310nm, 1490nm, 1550nm & 1625nm dBm/W (absolute) + dB (relative) measurement Extended Graphical display for optimal viewing Zero reference with dBm value displayed dBm and Watts displayed simultaneously Set Reference Feature for all calibrated wavelengths 0.1dB/0.01dB Resolution (Selectable) Meter calibration certificate includedDisplay back lightAuto power off (10 or 30 min option) N.I.S.T. traceable Single mode and multimode applications Dynamic range ~+6 to -60dBm.
