The Optical Wavelength Labs DO2st Dual OWL 850nm & 1300nm Multimode Optical Light Source (ST Connector) is a compact, handheld light source. The temperature compensated outputs are calibrated to couple -20dBm of optical power into multimode fiber. The light source comes installed with the two most commonly used multimode wavelengths - 850nm and 1300nm.

The source is simple to operate with an intuitive two-button interface for controlling power and port 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 a 7-segment LED display.

The Dual OWL fiber optic light source offers exceptional value at an economical price. The LED-based source provides the fiber optic installer with a stable output when testing multimode fiber optic runs. The Dual OWL combines an 850nm and a 1300nm LED into one light source to provide the widest range of options for multimode optical fiber testing.

The DO2-85st Dual OWL Light Source comes configured with an ST connector port, 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.
