In the past, fiber optic power meter and fiber optic light source are two different type of fiber optic test equipment; they are usually used together to form the pair in the fiber optic test work. Fiber optic multi meter is a combo of the two, it combines the function of fiber optic power meter and fiber optic light source and the user can easily switch to choose the multi meter function by press the simple control buttons.

The fiber optic multimeter test range is classified by -70dBm to +6dBm and -50dBm to +26dBm as two types. Typical working wavelength for this multimeter is 850nm, 980nm, 1300nm, 1310nm and 1550nm in each single unit. Its fiber optic interface is FC Universal 2.5mm adaptor. Ouput power at -7dBm, spectral Width less than 10nm,Output Stability ±0.05dB/15mins; ±0.1dB/ 8hours
Modulation Frequencies is 270Hz, 1KHz, 2KHz. using the Rechargeable Battery + Battery Charger, it can work continuously for 6 hours under both power meter and light source function or work continuously for 26 hours for only power meter function. It is designed with an auto-off function and it can cut off the power if not work for more than 10 minutes.

This fiber optic multimeter is small in weight (net 300g) and measurement. (180mmx90mmx36.5mm) And is a useful tool for fiber optic network maintenance and testing.
