OWL ST 1300nm Multimode, NIST traceable, -20dBm

Reference#: 72168
Item#: OW-DO2-13ST


The Dual OWL 1300 is a cost effective, 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 an 1300nm LED source.  The source has an intuitive two-button interface one button for turning the unit ON or OFF and the other for wavelength selection.  LED indicators highlight the selected source and verify that battery power is sufficient to maintain the calibrated output power.  Dual OWL series fiber optic light sources offer exceptional value at an economical price.  These LED-based sources provide the fiber optic installer with a stable output when testing multimode fiber optic runs.  The Dual OWL 1300 offers the fiber optic professional with a simple, yet affordable, option for testing multimode fiber  links at 1300nm, and can be easily upgraded to include an 850nm source.  High intensity LEDs such as the ones in Dual OWL light sources produce intense beams of infrared energy that are invisible to the eye.
