Tempo OPM520 - Optical Power Meter (+27 to -50dBm)

The OPM520 power meter measures optical power at 850, 1300, 1310, 1490, 1550 and 1625nm between a power range of +27 to -50dBm. The OPM520 is supplied standard with a SC bulkhead adapter with LC, ST and FC adapters optionally available.

The Tempo Communications Optical Power Meters (OPM510/520) are available in standard and high-power versions for the Telco and MSO markets. Absolute and referenced power measurements ensure fast and accurate loss budget and insertion loss measurements. When placing tones on the fiber using a Tempo Communications source provides the optical power meter will definitively identify fiber optic cables.

The ruggedized IP54 compliant package provides test confidence when testing singlemode and multimode networks.

Keypad functions

: Push the power button to turn th OPM on or off. The default setting will turn the OPM off after five minutes of inactivity. Hold the power button for two seconds to place the OPM into a constant on mode. Holding the power button again for two seconds will revert to the auto off mode.

dB/dBm: Press this key to switch the measurement mode between absolute power (dBm) and relative loss (dB). Hold the key until “HELD” is displayed.

Zero: Press the Zero key to zero the OPM with the input port protected from ambient light. A message of “SUCC” will be displayed upon successful zeroing. If an “ERR” message appears check that the input port was in fact covered properly and repeat the zeroing procedure.

REF: Press this key to display the reference value stored in memory. Hold the key down until "HELD" appears in the display. When the OPM is switched to dB mode, the LCD displays the difference in dB between the reference level and the current input signal.

: Press this key to select the desired wavelength. The current wavelength will be displayed on LCD.
