OPM-M1 & OPM-M2

Optical Power Meter

The OPM-M1 or OPM-M2 Optical Power Meter is mainly used for checking the signal output power of the optical communication equipment in fiber-optic networks. It measures the average power of a continuous light beam which is emitted from the equipment or other optic sources. It measures power in both 850 nm (Multimode) and 1310 nm / 1490 nm / 1550 nm (Single-mode) respectively.

The universal connector can be used for all the most common fiber interfaces such as ST / SC / FC, and it is suitable to test both Single-mode and Multimode cables. With an optical 2.5 mm to 1.25 mm adapter, users can even test for a 1.25 mm fiber interface.

  • Robust, handy design with LED digital readout.
  • Easy to check Multimode 850 nm output power.
  • Easy to check Single-mode 1310 nm / 1490 nm / 1550 nm output power.
  • Universal 2.5 mm to 1.25 mm adaptor for SC / ST / FC to LC or MU
  • 3 Digits resolution and Low Voltage Battery warning LED display.
  • Measuring power in within -40 dBm ~ +5 dBm ranges.
