  • How to test the optical attenuation of a beam splitter

    How to test the optical attenuation of a beam splitter

    First, attach a launch reference cable to the optical light source of the proper wavelength (some splitters are wavelength dependent), and then calibrate the output of the launch reference cable with the optical power meter to set the 0dB reference. Whether an optical splitter is combining signal in the upstream direction or dividing signals in the downstream direction, it still introduces the same attenuation to an optical input signal. Before discussing the details of splitter loss testing, here is a fact that we should know about it. SPLITTER ATTENUATION DEVICE BA-1 B. 77-858 (Accessed February 10, 2025) If you have any questions about this publication or.
