FPM300 Series intelligent Optical Power Meter

Auto-wavelengths Recognition, Referencing Function, Computer Supported, used with FLS300 series Laser/Light Source.

General Details

FPM300 Series Optical Power Meter is a functional and intelligent OPM series. It could be used under the situation of laboratory, LANs, WANs and CATV as well as long distance optical networks. The FPM300 OPM with advanced features as follow:

Auto-wavelengths Recognition:
FLS300 Optical Laser Source can transmit with an encrypted wavelength identification digital protocol, enabling FPM300 Series Optical Power Meter to automatically switch to the proper calibration wavelength. This feature reduces the need for communication between the two technicians and decreases the possibility of making mistakes.

Referencing Function:
Signal encrypting can also give the receiving end information on the power to be used as reference, helping ensure efficient referencing, even when the two units are far apart.

Data Storage Supported:
Memory capacity of 1,000 data items; enables data transfer to a PC via USB connection. With the software, the test result can be saved as excel .xls file, notepad .txt file, and print out directly.

Testing Range:
Maximum testing range up to 150km (when using FLS300 Optical Laser Source).
