Description
The Fiber OWL 4 is a highly accurate hand-held optical power meter, capable of performing a wide range of
functions from simple optical power and loss measurements to standards-based link certification. Its built-
in Link Wizard walks the user through a series of steps, prompting the user to pick the parameters of their
link under test, and sets an optical reference based on these parameters. This optical reference is used as a
point of reference by which a link will PASS or FAIL against the chosen fiber standard. When used with OWL
WaveSource fiber optic light sources, the Fiber OWL 4 provides fiber optic professionals with automatic
wavelength switching so that the meter and light source are always set to the same wavelength, and
automatic dual-wavelength storage cuts down on testing time and human error. Up to 1000 fiber runs can
be stored memory, and can be downloaded into a PC using our free OWL Reporter software via the supplied
serial cable. OWL Reporter displays fiber tests in either a summary or detail view, and prints out
professional-looking certification reports that can be passed along to customers as proof of link certification.
Data can also be saved to hard disk for later retrieval. A 2.5mm universal and 1.25 universal connector port
are included to connect to a wide variety of popular fiber optic connectors, including SC, ST, FC, LC, and
SFF. A filtered detector option is available for high-power applications such as CATV and telco (”C”
versions), and the Fiber OWL 4 BOLT (”B” versions) comes configured with an integrated length tester used
for accurate optical length measurement of a fiber link. The Fiber OWL 4 is enclosed in high-impact plastic,
and a protective rubber boot provides additional shock protection. It’s large backlit display is easy to read,
and the 18-key pad allows for easy data entry. It can be used in many test environments, including LAN,
MAN, WAN, FTTH, Telco, CATV, Manufacturing, and Laboratory.
Applications include:
– Certification Testing – Attenuation Testing – Optical Loss Testing
– Active Equipment Optical Power Testing – FTTH Link Loss Verification – Patch Cord Testing

Test Equipment
The Fiber OWL 4 BOLT uses OWL’s optical length testing technology as a
unique, low-cost alternative for users who need to measure the length of
optical fibers. Fiber installations are increasingly required to have fiber
length measurements to comply with bid requirements. Kits including the
Fiber OWL 4 BOLT fit the bill nicely. The length tester in the Fiber OWL 4
BOLT use a “round-robin” method of measuring fiber length. This is
accomplished by looping back two fibers at one end of the fiber run with a
patch cord. The round trip time that the light takes to travel through both
fibers is converted to length in kilometers, then divided by two to show the
length of the fiber cable. There is no need to measure the length of all the
fibers; the length measurement can be applied to all fibers in the cable. This
method of length testing provides accurate measurements, and saves time
and money. Measuring fiber by the jacket or manual length measurement
are accepted methods of measurement; however, there are many scenarios
where this may not be possible. Length markings may be hard to reach if
they are already terminated in a patch panel, and networks that contain riser
cables may not be accurately measured. Optical measurement of fiber
produces accurate results without the need for jacket markings or manual
length measurement.

NOTE: the Fiber OWL 4 BOLT is not an OTDR-like device. It does not measure distance to a
fault, but measures the total length of a fiber link based on a two-fiber loopback method.
