Overview of the 1300 and DUAL OWLs
The 1300 OWL is a perfect match for The Fiber OWL II or Micro OWL optical power
meters. It is a fiber optic light source designed to test multimode fiber links such as data
LAN's and voice PBX's. The 1300nm LED provides power meters with a stable -20dBm
output source. The LED indicator confirms that the source is ON and that the battery has
enough power to maintain its calibrated output power. The 1300 OWL can be upgraded
to a Dual OWL by adding an 850nm LED light source. The Dual OWL can be used to
perform dual wavelength testing conforming to EIA/TIA testing standards TIA/568-A and
TIA/526-14A. The 1300 OWL is equipped with either ST (standard) or SC (additional
cost) connectors. Also, one additional laser source instead of an 850nm LED can be
obtained for the 1300 OWL. Select from the 1310 or the 1550 laser light source to fill the
empty DUAL OWL port. Lasers are available in ST, SC or FC connector styles.
Overview of the 1310, 1550, and Laser OWLs
The 1310, 1550 and Laser OWLs are laser-based light sources designed to test single
mode fiber optic links. They provide power meters with a stable –10dBm output.
Communications devices that use single mode laser light at 1310nm minimize chromatic
dispersion. Note that most glass optical fibers have minimal chromatic dispersion
characteristics near 1310nm. Communications devices that use single mode laser light
at 1550nm minimize optical attenuation.
The Fiber OWL II or Micro OWL optical power meters are ideal for use with the 1310,
1550 and Laser OWLs. The front panel LEDs indicate whether the unit is ON or OFF,
and whether the battery has enough power to maintain its calibrated output power. The
1310 OWL (or 1550 OWL) can be upgraded to a LASER OWL (combo of 1310 and 1550
OWLs) by adding a 1550nm (or 1310nm for the 1550 OWL) laser light source. The
LASER OWL can be used to perform dual wavelength testing that conforms to EIA/TIA
testing standards TIA/568-A and TIA/526-14A. The 1310, 1550, and Laser OWLs are
equipped with FC connectors (standard) or SC, ST connectors (additional cost).

Basic Operation

The selector switch on the top of the unit is used to select the desired wavelength (move
switch to the left or right). Return the switch to the center position to shut down the unit.
Note that if the indicator light on the selected wavelength is dim, replace the battery.
Caution: Never look directly into a powered light source.
