UNIT 1 INTRODUCTION
The FiberMeter is a high accuracy, high resolution, microprocessor controlled, optical power meter. The meter has a wide dynamic
range making it ideal for both single and multi-mode fiber testing.
TM
It has an attractive handheld case made from high impact Valox plastic, a large, backlit, graphic, liquid crystal display, and 18-key
keypad for easy data entry. The universal fiber adapter accepts both ST, SC, and FC connectors. It will operate for over 200 hrs on a
standard 9v battery and has built in auto shutdown.
The FiberMeter includes a built-in link wizard that helps you easily calculate the allowable loss for the fiber runs that you will be
measuring. The meter stores physical fiber information for up to eight links. Link information includes: link name, date, fiber type, fiber
length, connectors, splices, temperature, and calculated or entered reference power values for six wavelengths. In addition the meter
will store up to 900 measured data points with labels. Each value includes the fiber type and link.
The stored information can be selectively viewed, edited (measured again), printed, or deleted. The meter will print formatted reports
of selected stored data directly using the built in serial port, or all of the stored data can be downloaded to a computer spreadsheet or
our free Reporter software to produce professional-looking formatted certification reports.
Description
The FiberMeter can be used for several applications. A listing of these applications and their descriptions follows:
Attenuation Measurements - After a fiber cable has been installed and terminated, it must be tested to determine if the fiber is
installed according to standards and specifications. A comparison of the actual power measurement and the reference value
determines if the installation will PASS or FAIL.
Fiber Network Certification Using Various Cabling Standards - The FiberMeter uses a loss wizard that is used for fiber
certification against several cabling standards. The user is prompted to choose a standard, which allows the FiberMeter to calculate a
certification reference value for that standard and store it in the meter. As the user stores data points in the meter using the loss wizard,
the actual power level of the link is also stored. The data is then downloaded into our Reporter software, where the actual power value
is compared to the reference value. Certification reports can be printed out with details or summaries of the fibers being certified.
Fiber Continuity Testing - Continuity can be measured with the FiberMeter by placing a calibrated light source on one end of the
fiber and the FiberMeter on the other end. This is also a simple way to measure the attenuation of the fiber.
Patch Cord Testing - Fiber links that are producing incorrect results may have bad patch cords. The FiberMeter can be used to test
the attenuation of a patch cord to see if it is usable, or should be thrown out.
Active Equipment Optical Power Measurements - Active equipment needs to be measured periodically for correct power
levels and stability. The transmitters in this equipment have a known power value. The FiberMeter can be directly attached to this
equipment via a patch cord to check whether the transmitter is stable and is within the manufacturer’s specified power range.
