The TREND Networks 33-928 is a FiberMASTER – MM/SM power meter with MM 850nm light source allowing the user to measure absolute power and calculate the loss of fiber 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 fiber 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.
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 mW (milliwatt) 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 specifications. For example, most fiber 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 fiber optic cabling from end-to-end to determine the link loss of the system. To use this mode, the power meter must first 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
- Wavelength measurement annunciator.
- Numeric display for power and loss measurements. Also displays “null” when power is below detection level.
- Decibel toggle button. Press to change between power measurement mode (dBm) and loss calculation mode (dB). Changing to dB mode automatically stores the cur- rent input level as the reference for loss calculations.
- Power button.
- Unit of measure annunciator, displays either dBm, dB or mW.
- Wavelength select and dB/mW toggle button. Press and release to change wavelength between 850/1310/1490/1550nm. Press and hold for 2 seconds then release to toggle between dBm and mW modes.
Light Source Indicators and Functions
The power output of the light source will vary slightly during the first five minutes of operation as it warms to operating temperature. To ensure best measurement accuracy, allow the light source to operate for five minutes before calibrating the meter or making measurements.
- Power LED. Lights green when light source is active.
- Power button.
- Low Battery LED. 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.
