Product Description

Power Meter (850/1300/1310/1550/1625nm)


  • Calibrated wavelength: 850 nm, 1300 nm, 1310 nm, 1550 nm and 1625 nm
  • Detector Type: InGaAs
  • Measurement Range: -70 dBm to 6 dBm
  • Measurement Unit: dB, dBm, uW
  • Power: 2 x AA batteries, optional NiMH

Knowledgebase: The OPM 4-3D optical power meter may be used to measure optical power in Premises, Telco, or Broadband fiber optic networks. When used with an LED or Laser light source, the OPM 4-3D also measures insertion loss of multimode or single-mode cables. The OPM 4 stores optical references for each calibrated wavelength. An easy to read Dual Wavelength LCD display with Backlight shows measured power [dBm or ?W] or insertion loss [dB], calibrated wavelengths, tone signal [Hz], wavelength ID, and the battery charge status. In addition to being powered by two AA alkaline, the OPM 4-3D can be powered by optional rechargeable NiMH battery pack. The OPM 4-3D optical input port accepts Noyes thread-on style adapter caps. Adapter caps are required for operation and must be ordered separately. The OPM 4-3D is fully N.I.S.T. traceable. Rugged, handheld, lightweight. The OPM 4-3D specifications are:

FPM-302X = High-power Ge detector. The FLS-300 or FOT-300 units can transmit with a wavelength-identification digital encrypted protocol, enabling the FPM-300 Power Meter to automatically use the proper calibration parameters. This feature reduces the need for communication between the two technicians and decreases the potential for error.
