Includes power meter, LED source, and travel case.

The rugged Fiber Optic Power Meter and LED Source Kit from Black Box are designed to precisely measure power loss in fiber optic components under field conditions. The fiber optic power meter and the LED source work together to measure power loss in fiber optic cable, connectors, attenuators, or other passive optical components.

Fiber optic power meter
The fiber optic power meter is calibrated at four wavelengths: 850 nm, 1300 nm, 1310 nm, and 1550 nm. It measures power levels as high as +20 dBm and as low as -60 dBm. It features a true resolution of 0.01 dBm at all power levels so you can trust measurements below -45 dBm.

Our fiber optic power meter provides response time up to five times faster than other units. In fact, at most power levels, readings are instantaneous.

In relative measurement mode, the meter stores the zero reference reading for all four wavelengths independently in nonvolatile memory. This enables you to turn off the meter to save battery life as you move between testing locations. The meter also displays a 1-dB analog-type deviation pointer and an unaveraged mini display for real-time splice tuning.

The meter stores up to 999 test results per wavelength. You can upload these readings to a PC for printing and analysis.

LED source
The LED source supplies the temperature-stabilized light output the fiber optic power meter requires. It provides output wavelengths of 850 nm and 1300 nm through dual LEDs, which can be operated one at a time or simultaneously in CW, 30 Hz, 500 Hz, or 2 kHz modulation.
