OWL ST 1310nm and 1550nm, SingleMode, NIST traceable, -10dBm, Laser Source

Reference#: 72186
Item#: OW-LO2ST


The Laser OWL singlemode laser source provides high output and stability in an economical price.  The laser diodes use temperature compensated  outputs, and are calibrated to couple -10dBm of optical power into  singlemode  fiber .    The source is simple to operate with an intuitive  2-button interface one button to control power and the other to select output wavelength.  LED indicators highlight the selected source and verify that battery power is sufficient to maintain the calibrated output power.  The Laser OWL is a laser-based light  source designed to test singlemode fiber  optic links.  The LED indicator shows whether the unit is ON or OFF, and whether the battery has enough power to maintain its calibrated output power.  Its dual-wavelength 1310 and 1550nm light  sources provide dual wavelength testing that conforms to international testing standards. Lasers such as the ones in Laser OWL light sources produce intense beams of infrared energy that are invisible  to  the  eye.
