Name: Optical Fibre Power Meter – NF-900
Rating: 0 (0 reviews)

NF-900 Optical Power Meter is a compact and an easy-to-use testing instrument for optical fiber networks, which can be used for absolute optical power measurements as well as for relative loss measurements in optical fibers. It features ingenious appearance, wide range of power measurement, high accuracy and user self-calibration function with high performance-to-price ratio.

Main functions:

1. Measurement of the power of optical sender (dBm and W).

2. Insertion loss test of optical devices.

3. New REF user-defined.

4. FC/SC/ST general-purpose interface.

5. Wavelength:850/1300/1310/1490/1550/1625nm.

Caution:

1.Don’t connected high voltage lines to avoid buring out the machine.

2.Put into the right place to avoid hurting others,because of the sharp part.

3.Connected the cable to the right port.

4.Read the user manual before use it.
