The Optical Wavelength Labs WS-MDVST WaveSource 850/1300nm Multimode Optical Light Source with Integrated Visual Fault Locator (ST Connector) offers fiber optic professionals a high quality option for multimode fiber testing in a compact, handheld package. The temperature compensated outputs are calibrated to couple -20dBm of optical power into multimode fiber. The light source comes with 850/1300nm LED sources and a visual fault locator (VFL) installed.

The WaveSource light source is simple to operate with an intuitive four-button interface controlling power, port selection, transmission mode, and wavelength/AUTO selection. LED indicators highlight the selected source port and verify that battery power is sufficient to maintain the calibrated output power. Wavelength is indicated by 7-segment LED display.

The WaveSource has two transmission modes: Continuous Wave (CW) for accurate temperature-stabilized fiber optic tests; and modulated mode. Modulated mode provides for an auto-testing function when used with the Fiber OWL 4, Micro OWL 2, and WaveTester power meters (all sold separately). The AUTO mode allows simultaneous dual-wavelength testing, cutting testing time in half over single-wavelength sources.

The WS-MDVST WaveSource light source comes configured with ST connector ports and integrated VFL, as well as a protective rubber boot, re-chargeable Lithium Polymer battery and charger, NIST-traceable certificate of calibration, and CD-ROM with operations manual.
