Introduction
Congratulations on your purchase of the Extech LED or LASER light source. Light
sources emit light at a certain wavelength in nanometers (nm), which is detected at the
other end of a fiber by a photo detector calibrated to the same wavelength. The center
wavelength of the light source is measured at the point of peak intensity. Light sources
emit a range of wavelengths, not just one. The difference between the lowest and the
highest frequency of light is called the spectral width. For practical purposes, spectral
width is measured at Full Width-Half Maximum (FWHM); the width (Full Width) is
measured at the point exactly halfway between zero power and peak power (Half
Maximum). Careful use of this source will provide years of reliable service.
EXTECH INSTRUMENTS CORPORATION warrants the basic instrument to be free of
defects in parts and workmanship for one year from date of shipment (a six month limited
warranty applies on sensors and cables). If it should become necessary to return the
instrument for service during or beyond the warranty period, contact the Customer
Service Department at (781) 890-7440 EXTENSION 210 for authorization or visit

issued before any product is returned to Extech. The sender is responsible for
shipping charges, freight, insurance and proper packaging to prevent damage in transit.
This warranty does not apply to defects resulting from action of the user such as misuse,
improper wiring, operation outside of specification, improper maintenance or repair, or
unauthorized modification. Extech specifically disclaims any implied warranties or
merchantability or fitness for a specific purpose and will not be liable for any direct,
indirect, incidental or consequential damages. Extech's total liability is limited to repair or

Overview of the 850 and DUAL OWLs
The 850 OWL can test multi-mode fiber links such as premise LAN’s and voice PBX’s.
The 850nm LED provides 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 Dual OWL can be used to perform dual wavelength testing that
conforms to EIA/TIA testing standards TIA/568-A and TIA/526-14A. The 850 OWL is
equipped with either ST (standard) or SC (additional cost) connectors. In addition, a
1310 or 1550 laser source, instead of a 1300nm LED, can be ordered (lasers are
available in ST, SC or FC connector styles).
