How to Use Optical Power Meter for Optical Power Measurement?

How to Use Optical Power Meter for Optical Power Measurement?

FS Official Nov 21, 2016

FS provides several optical power meters with similar functions and buttons, but they may differ in interface types according to the connectors of tested fiber patch cables.

In this video, we’re going to use FS self- developed handheld optical power meter (FOPM-104) to measure the optical power of Cisco compatible 10GBASE-LR SFP+ module installed on Cisco Nexus 9396PX switch. A single-mode LC-FC fiber patch cable is required as 10G-LR SFP+ transceiver is a single-mode transceiver working on wavelength of 1310nm. After connecting the optical power meter to the module, turn on the power button and press λ button to select 1310nm wavelength. At first the power value will change rapidly, then it slows down to be static with the final power value -2.06 shown on the screen. The final value falling in the range of -8.2 to 0.5 demonstrates that this transceiver is functioning well.

The optical power meter adopted owns many practical functions and sends high accuracy in performance. With this OPM, users can easily achieve either absolute optical power measurement or relative loss measurement. For your reference, you can see the video DWDM MUX/DEMUX Insertion Loss Test, which uses this OPM to test the typical insertion loss of our 40-CH DWDM MUX/DEMUX. This test is also done quickly thanks to the self-calibration and reference power setting features.
