Fiber Optic Testing Kit
Instruction Manual
Introduction
The IDEAL FiberMASTERTM ber optic testing kit allows
the user to measure absolute power and calculate the
loss of ber optic links at several wavelengths. Absolute
power measurements are helpful when trouble shooting
equipment that may not be operating properly. The dB
calibration feature allows the operator to set a reference
level to the light source and directly read the loss of ber
optic links without needing to manually calculate the values. The unique form
factor allows the light source to be docked neatly within the power meter. This
makes the kit compact for easy storage while still allowing full operation of both
the source and meter.

ADVICE AND PRECAUTIONS
Laser Warning:
• Do not look inside the optical ber port when the FiberMASTER is
operating. The emissions can be dangerous and cause permanent
damage to your vision.
• To prevent damage to the lens, do not insert items other than optical
connectors into the port of the FiberMASTER.
• Do not look into the ber if it is connected to an active device. The
wavelength of the light transmitted by the equipment is invisible to
the human eye and may cause permanent vision damage.
• Always assume that a ber optic cable is connected to an active
device that is emitting dangerous, invisible light.
General Operation
FiberMASTER operates in two basic modes; absolute power measurement
and relative power measurement.
Absolute power measurement is the measure of the strength of the light
energy coming into the power meter. This mode is indicated by the dBm
(decibel milliwatt) or µW (microwatt) annunciators in the LCD display. This
mode is helpful when measuring the output of an optical device to determine
if it is operating within its specications. For example, most ber optic
network devices specify their typical output power in dBm. By connecting the
FiberMASTER power meter to the output of a network device the direct power
can be instantly measured to isolate a faulty transmitter.
Relative power measurements are used to calculate the difference in power
between two measurements. This mode is indicated by the dB annunciator
in the LCD panel. This mode is used mostly by installers when measuring
ber optic cabling from end-to-end to determine the link loss of the system.
To use this mode, the power meter must rst be connected to a stable light
source then that power level in stored in the meter’s memory. Then future
measurements are compared to the stored reference value and the difference
is calculated and displayed as dB.

Power Meter Display and Functions
1. Wavelength measurement annunciator.
2. Numeric display for power and loss measurements.
Also displays “null” when power is below detection
level.
3. Decibel toggle button. Press to change between power
measurement mode (dBm) and loss calculation mode
(dB). Changing to dB mode automatically stores the
current input level as the reference for loss calculations.
4. Power button.
5. Unit of measure annunciator, displays either dBm, dB or µW.
6. Wavelength select and dB/µW toggle button. Press and release to
change wavelength between 850/1300/1310/1490/1550nm. Press and
hold for 2 seconds then release to toggle between dBm and µW modes.

Light Source Indicators and Functions
1. Wavelength LEDs. Lights green to indicate active
source. Blinks red when battery is low. At 3.6V unit will
power off after 10 minutes. At 3.3V unit will power off
after 5 seconds.
2. Power button. Press the toggle wavelength, hold to
power off.

The power output of the light source will vary slightly during the rst ve
minutes of operation as it warms to operating temperature. To ensure best
measurement accuracy, allow the light source to operate for ve minutes
before calibrating the meter or making measurements.
