Introduction

The IDEAL FiberMASTER

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.

Product Features

• 850, 1300/1310, 1490 and 1550 wavelength measurement capability

on power meter

• 850/1300/1310/1550nm laser light source (33-931 kit)

• Power measurement in dBm and µW, loss display in dB

• Power meter auto power off

• Operates on standard AAA batteries, three in each unit

• Includes universal adapter for power meter and ST, SC and FC adapters

for light source

• Includes rugged carrying pouch, multimode and single mode SC jumpers

and calibration coupler

ADVICE AND PRECAUTIONS Laser Warning: • Do not look inside the optical fiber 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 fiber 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.

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.

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. 1 2 The power output of the light source will vary slightly during the first five minutes of operation as it warms to operating temperature.

Basic Operation Measuring Optical Power Important: When the power meter is first turned on it self-calibrates to a “no light” condition which is necessary for accurate measurements. THE DUST COVER MUST REMAIN ON THE POWER METER PORT WHEN IT IS FIRST TURNED ON. 1. With the dust cap on the power meter, press the power button. The meter will display ‘null’, indicating that it is ready to measure and is currently receiving no power. Press the wavelength ‘λ’ button to change to the desired wavelength. 2.

Measuring Cabling Loss Loss measurements are performed to certify a cabling link meets certain criteria for attenuation. Loss (dB) can be manually calculated by subtracting the power (dBm) through the cabling under test from the power (dBm) of the light source when connected directly to the meter. To make this process easier FiberMASTER includes a calibration function that stores the light source power level and compares it to future readings and directly displays loss in dB on the LCD panel. 1.

Calibration Procedure Diagrams The following diagrams supplement steps 1–4 on the previous page. Affix the black dust cap to the input of the power meter. Clear dust caps dBm allow ambient light to pass and cannot be used. Turn on the power meter and wait for ‘null’ to be displayed on the LCD. The meter is now ready to use. nm Connect known good reference jumpers between the light source and power meter. In this example two jumpers are used in conjunction with a coupler.
PAGE 8
Press the ‘dB/Cal’ button to store the reference value. The LCD will display ‘0.00dB’. The meter is now measuring loss. nm Repeated pressing of the ‘dB/Cal’ button again will change between the dBm power measurement mode and dB loss measurement mode. Each time the meter enters the dB mode it stores the current power level as a new reference level. Once the calibration value is set, do not toggle out of the dB mode. Otherwise it will be necessary to perform the calibration step again.
