1.0 GENERAL
MPO light sources are designed for testing 12-fiber MPO/MTP cabling, with versions for multimode @ 850
and/or 1300 nm, and singlemode @ 1310 and/or 1550 nm. Please see the section at the end of this guide for
a complete list of configurations.
MPO light sources can be configured to automatically cycle through all 12 fibers, or manually switch via
intuitive push-buttons.
Thank you for your purchase of an Optical Wavelength Labs (OWL) MPO Series fiber optic light source.
MPO light sources also include a SC port for single fiber power/loss measurement, which is helpful when
testing MPO cabling attached to MPO cassettes.
The various models of MPO light sources contain stabilized multimode and singlemode sources designed for
accurate optical power and loss measurements, as well as polarity, in MPO fiber optic cables and links. Each
MPO light source comes with a protective rubber boot, operations manual on USB flash drive, and a USB
charger and cable.
Typical uses include telecommunications networks, data networks, cable television, and industrial equipment
control.

2.0 FUNCTIONAL DESCRIPTIONS
4. Single-fiber Port Indicator LED - This LED will either be
RED or depending upon which wavelength is selected.GREEN
11. 8 / AUTO button - Pressing this button will toggle the unit between wavelengths in the selected port
when there are two wavelengths in the same port. Holding this button will place the source into AUTO mode,
where the source automatically switches wavelengths for automatic dual-wavelength testing.
8. Next channel button - switches the source to the next
channel.
2.0.1 CONNECTIONS
9. Previous channel button - switches the source to the
previous channel.
1. Single-fiber Port - Enables single-fiber testing.
6. 12-fiber MPO Port B Indicator LED - This LED will either
be or depending upon which wavelength is selected.RED GREEN
10. Power button - Power the unit on or off.
7. Wavelength/channel display - briefly shows the currently
selected output wavelength, AUTO mode, and currently selected
channel. Channel 1-12 refer to the MPO channels, and channel 13
refers to the single-fiber port.

3.1.1 Safety - Exercise caution when working with optical equipment. Most transmission equipment and
light sources use light that is invisible to the human eye. High energy light is potentially dangerous, and can
cause serious, irreparable damage to the eye. Thus, it is recommended to look into the connector NEVER
port of a light source or the end of a fiber.
3.2.1 Cleaning Supplies - It is recommended to clean fiber ferrules before each insertion with 99% or better
isopropyl alcohol and a lint free cloth. A can of compressed air should be available to dry off the connector
after wiping, and to blow out dust from bulkheads.
3.2.2 Patch Cords - Patch cords may be needed to connect the MPO light source to the system under test.
The connector styles on the patch cord must match the type on the MPO light source and the type of the
system under test.
MPO light sources can be used as diagnostic and measurement tools of optical transmission systems and
fiber optic links. These applications can be found in several industries, including premise, LAN, CATV, and
Telco.
3.1 PRECAUTIONS
3.1.2 Operational - In order to ensure accurate and reliable readings, it is vitally important to clean ferrules
containing optical fibers and optical connector ports. If dirt, dust, and oil is allowed to build up inside
connector ports, this may scratch the emitting surface of the light source, producing erroneous results.
Replace dust caps after each use.

3.2 REQUIRED ACCESSORIES
3.2.3 Optical Fiber Adapters - Optical fiber adapters are used to connect two connectorized fibers together,
and may be necessary to adapt your patch cords to the system under test.
3.3 TYPICAL APPLICATIONS
MPO light sources are designed to emit a temperature-stabilized source of light to be used for optical loss
measurement. The MPO light source serves as an optical reference, which is otherwise known as the “zero”
point when a power meter is “zeroed”. Optical loss measurements are useful for measuring the attenuation,
or loss, of a fiber link. The loss value can then be compared to a pre-calculated link budget, which is used to
determine if the fiber link will operate within the parameters of the transmission equipment.
The formula for calculating loss in a fiber link is: L = P - P
a r
where L is the amount of optical loss in dB, P is the absolute power in dbm, and P is the reference power in
a r
dBm.
Optical loss measurements can also be used for fiber optic link certification. Link certification is a process
where optical loss measurements are compared to a link budget calculated using fiber optic cabling
standards.
